Update Basemap Layers using another Web Map

mpboyle — Tue, 21 Mar 2023 14:38:12 GMT

Is it possible to use the Python API to update the basemap layers of an existing web map to those of another web map?

For example, I have a template web map that has the base map configured as desired, and I'd like to use the Python API to iterate over several existing web maps and update the base map using the template web map.

Below is the code I've tried, but doesn't seem to do anything to the target web map:

import arcgis # set web map ids wmIDTarget = '...id1...' wmIDTemplate = '...id2...' # connect to portal p = arcgis.GIS('https://www.arcgis.com/', 'user_name', 'user_password') # create web map items wmItemTarget = arcgis.mapping.WebMap(p.content.get(wmIDTarget)) wmItemTemplate = arcgis.mapping.WebMap(p.content.get(wmIDTemplate)) # get template base map layer information templateBase = wmItemTemplate.basemap.get('baseMapLayers') # update target web map base map layers wmItemTarget.basemap.update({'baseMapLayers':templateBase}) wmItemTarget.basemap.update({'title':'Basemap Updated'})

Hi @mpboyle

See code below, let me know if any issues.

from arcgis import GIS ## connect to the AGOL/Portal instance p = arcgis.GIS('https://www.arcgis.com/', 'user_name', 'user_password') ## the id for the webmap to update wmIDTarget = "...id1..." ## the id to for the webmap to get the basemap info from wmIDTemplate = '...id2...' ## get as content items wmTargetItem = p.content.get(wmIDTarget) wmTemplateItem = p.content.get(wmIDTemplate) ## get basemap info from template basemap_data = wmTemplateItem.get_data()["baseMap"] ## apply to target target_data = wmTargetItem.get_data() target_data["baseMap"] = basemap_data ## update target webamp item_properties = {"text":target_data} wmTargetItem.update(item_properties=item_properties)

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
