Is there a way to create map series and print the series of maps in pdf within ArcGIS online?

Question

We have a situation that is described below. We are trying to show the competitor information. The map has three layers.

* Layer 1: 100 points representing 100 Starbuck Coffee store locations (example)
* Layer 2: all the competitors’ coffee shops within 10 km of those 100 Starbuck coffee stores in layer1
* We will create a summary layer that describe how many competitors within 10 km of each Starbuck coffee store.

We would like to print each 10KM circle area, the main Starbuck Coffee Store and the competitor coffee shops to one pdf. We will get 100 pdfs for the 100 stores. The sample is like below:

Is there a way that we can quickly create 100 maps with circles and corresponding information?

We are using ArcGIS online. Thank you in advance.

Hm, good question. I don't typically work with basemaps when I'm plotting in GeoPandas, but I'm sure it's possible.

Thank you so so much!

In your code,

layer1 = requests.get('your-service-url/query?', layer1_params)

layer2 = requests.get('other-service-url/query?', layer2_params)

I guess the url is the published map's URL which is shared.  All these have nothing to do with ArcGIS api. I can write the script on my local machine and grab the data, plot it, and print out. Will the base map information and points be the same as they are in ArcGIS?

I will try the solution. Thank you!!!

Believe it or not, but I think you'd be better served using something like GeoPandas for this. I say that because while the ArcGIS Python API has extensive "mapping" capabilities, it is entirely focused on interactive map "widgets", and does not do as well with exporting nice-looking static images.

GeoPandas, on the other hand, can work seamlessly with MapPlotLib to make really nice maps, which you can then include in a PDF.

import geopandas as gp
import requests

layer1_params = {
    'where': '1=1',
    'outFields': 'some, field, names',
    'f': 'geojson'
}

layer1 = requests.get('your-service-url/query?', layer1_params)

df1 = gp.read_file(layer1.text)

circ = df1.buffer(10000) # this assumes input df1 is in meters. this is dependent upon the spatial reference your layer is in. you can optionally request the parameter 'outSR' to change this at the request level

layer2_params = {
    'where':'1=1'
}

layer2 = requests.get('other-service-url/query?', layer2_params)

df2 = gp.read_file(layer2.text)

n = 0

# iterate over features in first layer
while n < len(df1):
    # get shape of feature
    shp = df1.loc[n, 'geometry']

# plot the shape
    m = shp.boundary.plot()

# subset second layer for features in circle, add to plot
    df2[df2.within(shp)==True].plot(ax=m)

n += 1

For the PDF portion, I don't have a handy example, but this post looks pretty useful: https://datatofish.com/export-matplotlib-pdf/

It's just a start, but you'll find plotting in GeoPandas very easy to configure.
