Search for Web Maps which contain a specific basemap

Daniel_Hardwick

Hello,

I am trying to do something quite trivial, but I am relatively new to Notebooks so wondered if someone could help.

Essentially all I want to do is find web maps which contain a specific basemap. I have used Notebook previously to do things like find web maps which contain a keyword, such as Planning, using:

webmap_search = gis.content.search("Planning", item_type="Web Map")
webmap_search

And I have searched through particular groups to find content within, but I don't know how to search for web maps which contain a certain basemap, for example OS_Open_Carto. Is this possible?

Thanks

@Daniel_Hardwick Yes! Here is how we can only show web maps that are shared publicly and owned by a specific user. Please let me know if this works for you!

items_from_search = gis.content.search(query="owner:<AGOL username>", item_type="Web Map", outside_org=False, max_items=1000)

for item in items_from_search:

try:

if (WebMap(item).basemap.title=="GB Light Grey")&(item.access=='public'):

display(item)

except Exception as e:

print("Unable to check basemap for '{}': {}".format(item.title, e))

Thank you for this post and these examples. It aided in developing this notebook. I wanted to share in case it was useful. ArcGIS Online Basemap Replacement Notebook Update

I have submitted an enhancement idea at the following URL to allow all of us to do this sort of operation without any coding. If you like it, please give it a kudos and maybe make a comment:

Thanks @xlt208 , that's fantastic.

I have the code now setup as follows:

items_from_search = gis.content.search(query="", item_type="Web Map",outside_org=False , max_items=1000)

for item in items_from_search:

try:

if WebMap(item).basemap.title=="GB Light Grey":

display(item)

except Exception as e:

print("Unable to check basemap for '{}': {}".format(item.title, e))

And it works. Is there a way to amend this further to only show webmaps which are shared publicly? Also by Map owner? If there is a some sort of guide with the list of available methods then please feel free to point me towards it 🙂 As I have tried a few with trial and error but can't quite get what I want in terms of only publicly available maps create by a certain user.

Thanks

Hello Daniel!

We can loop through the items in the search result and use WebMap.basemap to check their basemaps.

In the code snippet below, if the basemap of a web map item matches the basemap we are looking for ("Topographic"), we will display the item in the cell output.

from arcgis.gis import GIS

from arcgis.mapping import WebMap

gis = GIS("home")

items_from_search = gis.content.search(query="Redlands", item_type="Web Map", max_items=15, outside_org=True)

for item in items_from_search:

try:

if WebMap(item).basemap.title=="Topographic":

display(item)

except Exception as e:

print("Unable to check basemap for '{}': {}".format(item.title, e))

I hope this is helpful! Please let me know if you have any questions about this.

Thanks,

Lingtao
