This notebook

This notebook is part two of a series of Jupyter notebooks exploring how to computationally access, retrieve, and analyze cartographic collections on loc.gov.

This noteobok demonstrates methods to:

• retrieve metadata associated with files downloaded in Querying and downloading cartographic material from loc.gov

• retrieve metadata associated with the Sanborn collection

• analyze and visualize metadata

1. Required Prep: Install and import all of the Python modules we’ll need

Most of the modules we’ll be using in this notebook come pre-packaged with Anaconda. If you installed Jupyter Notebook using Anaconda, you’ll have all of the required packages except one: plotly. You’ll need to install plotly if it isn’t already installed. To install it, open a terminal window (outside of this notebook) and install plotly. One of the easiest ways of installing Python modules is by using pip, as in this tutorial from W3C: https://www.w3schools.com/python/python_pip.asp. If you have a preferred package manager, you may use that instead.

If you run the cell below and encounter any errors, be sure to check that all the packages are installed.

If you can’t install plotly and you are planning to skip those sections of this notebook, you can simply comment out the plotly import by adding a hash at the beginning of the line:

#import plotly.express as px 

Run the next cell to:

import modules.

↓ ↓ ↓ ↓ ↓ ↓

import time
import re
import json
from urllib.request import urlopen
import requests
import pandas as pd
import matplotlib.pyplot as plt
import plotly.express as px

2. Query for list of records

If you’d just finished the previous notebook, Querying and downloading cartographic material from loc.gov , then you’ve just downloaded a set of GIF images. These images represent all of the Sanborn Fire Insurance maps for 19th century towns named “Springfield”. If you haven’t completed the previous notebook, that’s ok. It’s not required.

Let’s retrieve the metadata associated with these files, such as titles, publication dates, and locations. We’ll save it as a CSV alongside your downloaded files, so you can refer back to it later.

If you were writing your own code, you would probably want to get the metadata at the same time you download the files, to minimize API requests and save time. But for the purposes of our demo, we’ll make new API requests to get the metadata.

If you remember, our search query was saved into the searchURL variable as https://www.loc.gov/collections/sanborn-maps/?dates=1800/1899&fa=location:springfield. Let’s recreate that.

We also created a get_item_ids function, to get the IDs of our query results. Let’s recreate that as well.

Run the next cell to:

create the get_item_ids function.

↓ ↓ ↓ ↓ ↓ ↓

def get_item_ids(url, items=[], conditional='True'):
    # Check that the query URL is not an item or resource link.
    exclude = ["loc.gov/item","loc.gov/resource"]
    if any(string in url for string in exclude):
        raise NameError('Your URL points directly to an item or '
                        'resource page (you can tell because "item" '
                        'or "resource" is in the URL). Please use '
                        'a search URL instead. For example, instead ' 
                        'of \"https://www.loc.gov/item/2009581123/\", '
                        'try \"https://www.loc.gov/maps/?q=2009581123\". ') 
    
    # Request pages of 100 results at a time
    params = {"fo": "json", "c": 100, "at": "results,pagination"}
    call = requests.get(url, params=params)
    # Check that the API request was successful
    if (call.status_code==200) & ('json' in call.headers.get('content-type')):
        data = call.json()
        results = data['results']
        for result in results:
            # Filter out anything that's a colletion or web page
            filter_out = ("collection" in result.get("original_format")) \
                    and ("web page" in result.get("original_format")) \
                    and (eval(conditional)==False)
            if not filter_out:
                # Get the link to the item record
                if result.get("id"):
                    item = result.get("id")
                    # Filter out links to Catalog or other platforms
                    if item.startswith("http://www.loc.gov/item"):
                        items.append(item)
        # Repeat the loop on the next page, unless we're on the last page. 
        if data["pagination"]["next"] is not None: 
            next_url = data["pagination"]["next"]
            get_item_ids(next_url, items, conditional)

        return items
    else:
        print('There was a problem. Try running the cell again, or check your searchURL.')

When we run a search query, we get a significant amount of metadata about each of the results. However, it’s not the full metadata about each item. For example, it doesn’t include location metadata. To get the full metadata, after we run our query we must then request each of the results’ item records.

We’ll run the get_item_ids function above, which runs our initial search query. It will save a list of item ids to the ids variable. Later, we’ll get the full item records and metadata for each atlas.

Run the next cell to:

generate a list of Springfield atlas records, and save their IDs to the variable ids. The cell will print out the number of results. This is the number of atlases downloaded in the last Jupyter notebook, and it is the number of rows our metadata CSV spreadsheet will have. We can use the len function to tell us the length of ids.

If you’d like to try a different query, update the URL in the searchURL variable.

↓ ↓ ↓ ↓ ↓ ↓

searchURL = 'https://www.loc.gov/collections/sanborn-maps/?dates=1800/1899&fa=location:springfield'

ids = get_item_ids(searchURL, items=[])
len(ids)

22

3. Harvest the metadata

Now we’ll write a function to request the full item record for each of our 22 search results. This function will fetch each item record as JSON, and retrieve selected fields we specify. For this example, let’s say that we want the following metadata fields:

• title

• notes

• location

• date

• item ID

In order to know how to write the function, we’ll need to understand how an item record is structured.

Run the next cell to:

look at how the metadata in an item record is structured, by looking at the first item in ids.

↓ ↓ ↓ ↓ ↓ ↓

# Get the id of the first item in our list
first_result = ids[0]
# Make the API call.
item = requests.get(first_result, params = {"fo": "json"})
# Tell Python to read the result as JSON.
item_json = item.json()
# Get the "item" section of the JSON record.
item_metadata = item_json['item']

print('---Metadata for the query\'s first result----\n')
print('Title: ')
print(item_metadata['title'])
print('\nNotes: ')
print(item_metadata['notes'])
print('\nLocation: ')
print(item_metadata['location'])
print('\nDate: ')
print(item_metadata['date'])
print('\nItem ID (URL): ')
print(item_metadata['id'])
print('\nView item record json in your web browser: ')
print(item_metadata['id']+'?fo=json')

---Metadata for the query's first result----

Title: 
Sanborn Fire Insurance Map from Springfield, Sangamon County, Illinois.

Notes: 
[' Feb 1884. ', ' 15. ']

Location: 
[{'illinois': 'https://www.loc.gov/search/?fa=location:illinois&fo=json'}, {'sangamon county': 'https://www.loc.gov/search/?fa=location:sangamon+county&fo=json'}, {'springfield': 'https://www.loc.gov/search/?fa=location:springfield&fo=json'}]

Date: 
1884-02

Item ID (URL): 
http://www.loc.gov/item/sanborn02163_001/

View item record json in your web browser: 
http://www.loc.gov/item/sanborn02163_001/?fo=json

Tip

Most web browsers have built-in JSON viewers. Try copying the link above labelled “View item record json in your web browser” into various browsers, to see how they each visualize JSON.

You can also view the full JSON item record in this Jupyter notebook by running item_metadata or print(item_metadata).

How is the metadata structured?

Notice in the output above that the Notes and Location values are in square brackets:

Notes: 
[' Feb 1884. ', ' 15. ']

Location: 
[{'illinois': 'https://www.loc.gov/search/?fa=location:illinois&fo=json'}, {'sangamon county': 'https://www.loc.gov/search/?fa=location:sangamon+county&fo=json'}, {'springfield': 'https://www.loc.gov/search/?fa=location:springfield&fo=json'}]

This indicates that these values are Python lists, containing multiple values. Each value in the list is separated by a comma. In Notes, there are two values in the list, and each is surrounded by single quotes.

In loc.gov, Notes is a general field that can contain a range of information. For Sanborns, it is used to hold publication date and number of sheets. In this example, the 15 indicates 15 sheets in this particular Sanborn atlas.

The structure of the Location field is a little more complicated. It’s a list, but each item in the list is a Python dictionary. The example Location above is a list of three dictionaries. The first dictionary in the list looks like this:

{'illinois': 'https://www.loc.gov/search/?fa=location:illinois&fo=json'}

Curly brackets are used around dictionaries; square brackets are around lists. This dictionary has a single “key:value” pair. The key is “illinois”. The value is a URL.

The URL isn’t useful for our purposes. For this example item, Location has three dictionaries, and their keys are: “illinois”, “sangamon county”, and “springfield”. This tells us that the atlas is in Springfield, Sangamon County, Illinois. Notice that the metadata itself doesn’t indicate any hierarchy between the locations.

When we harvest our metadata, we’re going to save it into a CSV file. For this CSV, any fields that contain lists will be split into muiltple columns. For location, we’ll get the keys (like “illinois”, “sangamon county”, “springfield”) and we’ll ignore the URLs.

Let's create a function that will harvest item record metadata into a CSV.

The function will:

• take our list of items (ids)

• use the API to request each item record as JSON

• extract the metadata fields we want from each record

• add those fields to something Python calls a “dataframe”

• save the dataframe as a CSV file

The functions in this notebook are large and do many things. In the real world, best practice for Python functions is usually to break them up into multiple small functions, where each function does one thing.

Run the next cell to:

create function get_metadata_from_ids for harvesting and saving our metadata to a CSV file.

↓ ↓ ↓ ↓ ↓ ↓

def get_metadata_from_ids(ids):
    # List the fields we want.
    fields = ['title', 'notes','location','date']
    # Create a blank dataframe
    metadata_dataframe = pd.DataFrame()
    # Iterate through the IDs in our list
    for id_url in ids:
        print('Getting metadata for: '+id_url)
        # Create a blank dictionary for each ID. 
        item_dictnry = {}
        # Add the item ID to the dictionary.
        item_dictnry['id'] = id_url
        params = {"fo": "json"}
        try:
            # Make the API call for item record
            item = requests.get(id_url, params=params)
            item_json = item.json()
            item_metadata = item_json['item']
            # Get the number of pages
            try:
                pages = len(item_json['resources'][0]['files'])
            except:
                pages = None
            item_dictnry['page_count'] = pages
            # Iterate through our list of desired fields
            for field in fields:
                # Check if the field is a list
                field_type = type(item_metadata[field])
                # If the field is a list, get all values from it
                if field_type==list:
                    # Check how long the list is
                    number_cols = len(item_metadata[field])
                    # Make a numerical list from the length
                    number_range = range(number_cols)
                    # For each place in the list:
                    for i in number_range:
                        # Get the place number as a string
                        i_str = str(i)
                        # If field is location, get keys from the dictionary
                        if field == 'location':
                            try:
                                placename = item_metadata[field][i].keys()
                                item_dictnry[field+i_str] = list(placename)[0]
                            except:
                                item_dictnry[field+i_str] = None       
                        # If the field isn't location, just get the list values
                        else:
                            try:
                                item_dictnry[field+i_str] = \
                                    item_metadata[field][i]
                            except:
                                item_dictnry[field+i_str] = None  
                #If the field isn't a list, get the field's value. 
                else:

                    except:
                        item_dictnry[field] = None                      

        #If anything goes wrong, make a CSV row of None values.
        except:
            for field in fields:
                item_dictnry[field] = None
        # Parse out the last section of the id URL
        item_dictnry['id_simplified'] = item_dictnry['id'].split('/')[-2]

        # Pause before making an API call for the next item.
        time.sleep(5)
    # Function output is the dataframe.
    return metadata_dataframe

Let's run the function above.

The function will create a Python dataframe of our metadata. A dataframe is like a super-powered table for data calculation and analysis. We’ll save that dataframe to a CSV file. The CSV file will be saved in the saveTo folder that you specify below. The filename will be metadata.csv.

Run the next cell to:

run the function get_metadata_from_ids and save the results to a CSV named metadata.csv into the folder you specify in the saveTo variable.

Be sure to edit saveTo to point to a folder on your computer.

saveTo = 'C:/Users/rtrent/jupyter-notebooks/sanborn-images/'

metadata_dataframe = get_metadata_from_ids(ids)

Tip

When the cell above finishes running, scroll down to the bottom where you will see the metadata_dataframe displayed. Dataframes display like spreadsheets.

4. Basic metadata analysis

Now you have a CSV spreadsheet of metadata. If you completed the previous Jupyter notebook, you also have image files for these atlases downloaded to your computer (we’ll assume for our purposes that you completed that notebook, but it’s ok if you haven’t).

All of the information in that CSV is also at hand in this Jupyter notebook, in what’s called a “dataframe”. Dataframes come with the “Pandas” Python library, and you can do lots of things with dataframes that you can’t easily do with dictionaries or lists.

In the last notebook, each of your image files was downloaded into a folder on your computer. These folders are named according to the ID of each item.

For example, you might have a folder called “sanborn02163_001”, containing a GIF image file for each page. These images belong to a Sanborn atlas with the id “sanborn02163_001”, which can be found online at https://loc.gov/item/sanborn02163_001

Using our dataframe of metadata, we can quickly pull up basic metadata about the atlas in the sanborn02163_001 folder, like location and date. We’ll do this by looking for the string ‘sanborn02163_001’ in the id_simplified column.

Run the next cell to:

look for metadata about the downloaded atlas sanborn02163_001. You can change “sanborn02163_001” below for any other atlas id (aka, folder) that you’ve just downloaded.

↓ ↓ ↓ ↓ ↓ ↓

item_id = 'sanborn02163_001'
metadata_dataframe[metadata_dataframe['id_simplified']==item_id]

	date	id	id_simplified	location0	location1	location2	notes0	notes1	page_count	title	notes2	location3
0	1884-02	http://www.loc.gov/item/sanborn02163_001/	sanborn02163_001	illinois	sangamon county	springfield	Feb 1884.	15.	15.0	Sanborn Fire Insurance Map from Springfield, S...	NaN	NaN

---

Found!

We can see that “sanborn02163_001” is a map of Springfield in Sangamon County, Illinois from February 1884. It has 15 sheets. (The number of sheets is in the notes field. We’ve also calculated it from the number of files in the JSON’s resource field, and saved this to the page_count column.)

Did we download any other atlases from the same Springfield in Sangamon County?

Let’s see. We’ll look in our dataframe for rows where the strings ‘illinois’, ‘sangamon county’, and ‘springfield’ appear in any of the location columns (alternatively, we could also search using the title field, but we’ll stick with the location field for now.)

Run the next cell to:

look for any other atlases we’ve downloaded for Springfield, Sangamon County, Illinois

↓ ↓ ↓ ↓ ↓ ↓

#List of location terms we want to find
look_for = ['illinois','sangamon county','springfield']
#List of columns to look in
look_in = ['location0','location1','location2']
# Create a new dataframe by looking at the values in all of the
# "look_in" columns and extracting all rows where that value is 
# in the list of "look_for" terms.

search_metadata = metadata_dataframe[
    metadata_dataframe[look_in].isin(look_for).all(axis=1)
]

	date	id	id_simplified	location0	location1	location2	notes0	notes1	page_count	title	notes2	location3

What if we want to analyze our overall results?

For example, what is the average number of pages in the atlases we downloaded?

Pandas and Numpy (another Python module) offer many functions for running calculations on data in dataframes. Here, we’ll use a simple one built into Pandas: the .describe() function. Used on the page_count column, .describe() can give us information such as:

• the average number of pages in the Sanborn map atlases we’ve downloaded

• the largest number of pages in any atlas we’ve downloaded

• the smallest number of pages in any atlas we’ve downloaded

• standard deviation of page counts

Run the next cell to:

get a summary of the number of pages in the atlases we’ve downloaded (min, max, and mean).

↓ ↓ ↓ ↓ ↓ ↓

print('Smallest number of pages of a downloaded Sanborn atlas:')
print(metadata_dataframe.page_count.describe()['min'])
print('Largest number of pages of a downloaded Sanborn atlas:')
print(metadata_dataframe.page_count.describe()['max'])
print('Average number of pages (mean) of the downloaded Sanborn atlases:')      
print(metadata_dataframe.page_count.describe()['mean'])

Smallest number of pages of a downloaded Sanborn atlas:
2.0
Largest number of pages of a downloaded Sanborn atlas:
93.0
Average number of pages (mean) of the downloaded Sanborn atlases:
21.681818181818183

5. Metadata charts

We can also visualize our results.

For example, we can analyze dates.

Using a Python module called matplotlib, we can chart the frequency of atlases published, by year.

Run the next cell to:

chart the downloaded atlases by publication year.

↓ ↓ ↓ ↓ ↓ ↓

#Create a column from "date" that only includes the year.
metadata_dataframe['year'] = metadata_dataframe['date'].str[:4]
#Tell python to interpret that column as a datetime.
metadata_dataframe['year'] = metadata_dataframe['year']\
    .astype("datetime64[ns]")
#Create the display
visualize = metadata_dataframe.year.groupby(
        metadata_dataframe['year'].dt.year
    ).count()
visualize.plot(kind="bar")
plt.title('Downloaded Sanborn Atlases, by Publication Year')
plt.xlabel('Publication Year')
plt.ylabel('No. of Atlases')
plt.show()

Or we could chart how many pages are in each atlas

Run the next cell to:

chart the downloaded atlases by number of pages per atlas.

↓ ↓ ↓ ↓ ↓ ↓

#Ignore any rows where page count is blank
page_count = metadata_dataframe[
        metadata_dataframe['page_count'].notnull()
    ].copy()
#Create the display
visualize = metadata_dataframe.page_count.groupby(
        page_count['page_count']
    ).count()
visualize.plot(kind="bar")
plt.title('Downloaded Sanborn Atlases, by Page Count')
plt.xlabel('No. of Pages')
plt.ylabel('No. of Atlases')
plt.show()

6. Metadata maps and Wikidata

Let's get a larger set of metadata, and visualize it with a choropleth map and timeline map.

Python has many visualization modules that build on Matplotlib. Here, we’ll use one called plotly. Let’s use it to visualize information about Sanborn mapping of Illinois counties over time.

To do this, we’ll need to get some extra metadata from Wikidata, about the counties’ locations.

Specifically, we’ll:

1. get metadata from loc.gov for all of the Illinois Sanborn atlases online

2. get location information from Wikidata for each Illinois county

3. map the atlases, by county and publication year

To combine the loc.gov data with Wikidata data, we’ll use something called a SPARQL query. This is how data is retrieved from Wikidata, using SPARQL.

First, let's write a new function that gets metadata about Illinois Sanborns from loc.gov.

For our location metadata, we need to get county names. In order to minimize the number of API requests we’ll make, let’s parse the county names from the title field rather than from the location metadata field. This will allow us to get all our information from our query results, without having to reach atlas’s individual item records. The location field is in the item records, but isn’t in the query result records.

The county metadata is a little messy. We’ll need to account for various types of “counties”, as in these examples:

• “Belle Glade, Palm Beach County, Florida” (standard pattern)

• “Cape Girardeau, Cape Girardeau, Missouri” (counties missing the word “County”)

• “Mankato, Blue Earth And Nicollet Counties, Minnesota” (two counties)

• “Kansas City, Jackson, Clay, And Platte Counties, Missouri” (three or more counties)

• “Saint Louis, Independent City, Missouri” (cities without counties)

• “New Orleans, Orleans Parish, Louisiana” (county-like entities)

• “Juneau, Juneau Census Division, Alaska” (county-like entities whose status has changed over time)

We’ll tackle this inside our function, with a series of regular expressions. More details are in the comments within the function.

Run the next cell to:

define the get_Sanborn_counties function, which creates a dataframe of atlases based on an API query. Any atlas that is labelled with more than one county (or county-like entity) will have a row for each county.

Great!

Now we have a dataframe of all the Illinois Sanborn atlases, split up so that there is one row per county per atlas.

In order to map data, mapping tools needs access to information about the counties’ locations. There are lots of ways to get this information, and different types of location information we can get.

For one of our maps, we’ll use a geojson file from Plotly that matches counties’ “FIPS” codes with polygons (county borders). FIPS codes are used by the Census Bureau and other U.S. federal agencies to uniquely identify counties and county-like entities. For another map, we’ll use coordinates for counties’ center points.

We’ll go to Wikidata to get the necessary data:

• county FIPS code

• county coordinates, which contains the center point latitude and longitude

First, we need to reorganize our dataframe so that we have one row per county. To do this, we can use the Pandas function .groupby().

Run the next cell to:

reorganize the atlases_df dataframe into a dataframe of counties, with one county per row, and save the new dataframe to counties_df. The count column will be the total count of atlases for that county.

The cell below will print the first 5 counties.

↓ ↓ ↓ ↓ ↓ ↓

counties_df = atlases_df.groupby(['county', 'state']).agg({'count': 'sum'})
counties_df.reset_index(inplace=True)
counties_df.head(5)

	county	state	count
0	Adams	Illinois	14
1	Alexander	Illinois	8
2	Bond	Illinois	9
3	Boone	Illinois	6
4	Brown	Illinois	7

Next, we’ll want to define a function to pull the FIPS codes and coordinates from Wikidata. We’ll want to feed our county column to the function, and get three new columns in return:

1. fips - fips code

2. lat - latitude

3. long - longitude

Our function will use a SPARQL query to get this information from Wikidata.

SPARQL queries

A good starting point to learn about Wikidata SPARQL queries is the Wikidata:SPARQL tutorial. SPARQL is an RDF query language broadly used for linked open data.

Run the next cell to:

define the get_fips_coords function, which retrieves counties’ FIPS codes and coordinates from Wikidata.

Clean up the data and map it!

Now we have the FIPS codes and coordinates from Wikidata.

Scroll to the bottom of the results above to look at the dataframe table.

Notice Cook county high on the list? Chicago is in Cook County, which explains why the county_bycounty value (123) is so high. county_bycounty is the total number of online atlase volumes for Cook county across all years.

Our data is ready for mapping.

First, let’s make what’s called a choropleth map, where Illinois’s counties are colored according to how many atlas volumes are online for that county. This visualization relies on the FIPS codes we pulled from Wikidata.

Run the next cell to:

generate a choropleth map of all Illinois Sanborn atlases online at loc.gov, by county.

(Tip: zoom in to get a closer look at Illinois!)

↓ ↓ ↓ ↓ ↓ ↓

#Retrieve Plotly's geojson file, which matches county FIPS codes with county polygons
geojson = 'https://raw.githubusercontent.com/plotly/datasets/master/geojson-counties-fips.json'
with urlopen(geojson) as response:
    counties = json.load(response)
    
fig = px.choropleth(
        counties_df, 
        title = 'Sanborn atlas volumes online, by County (Illinois)',
        hover_name='county', hover_data=['state', 'count'],
        geojson=counties, locations='fips', 
        color='count',
        color_continuous_scale=['#e6eff7','#005fa8'],
        range_color=(0, 100),
        scope="usa",
        labels={'count':'Atlas count'}
      )
fig.update_layout(margin={"r":0,"t":100,"l":0,"b":0})
fig.show()

Next, let's make a proportional dot map, with a timeline at the bottom.

This visualization relies on the coordinates we pulled from Wikidata.

Run the next cell to:

generate a timeline map showing the number of Illinois Sanborn atlases online at loc.gov, by county and year.

↓ ↓ ↓ ↓ ↓ ↓

#Customize the figure 
fig = px.scatter_mapbox(
        counties_by_year, 
        title = 'Sanborn atlas volumes online, by County and Year (Illinois)',
        lat='lat', lon='long', 
        hover_name='county', hover_data=['state', 'count'],
        size='count',
        color_discrete_sequence=["fuchsia"],
        animation_frame='year',
        height=440, zoom=4,
        center = {'lat':40,'lon':-88.8}
    )
#Use OpenStreetMap as the base layer
fig.update_layout(mapbox_style="open-street-map")
fig.update_layout(margin={"r":0,"t":100,"l":0,"b":0})
fig.show()

Tip

Press play on the timeline, or pull the timeline to see atlases published by year.

Atlases with publication dates in the mid-20th century are usually atlases originally published earlier, with updates later added.
