Using ArcGIS API for Python to List Offline Map Areas

Jan Tschada

In this blog post, we will look at how to use ArcGIS API for Python to list all offline map areas and their related items in all web maps of a specific ArcGIS Online account.<\/P>

Introduction<\/H2>The ArcGIS API for Python is a powerful library that supports ArcGIS Enterprise and ArcGIS Online and provides a consistent programming experience for scripting and automating across the entire ArcGIS product suite.<\/P>Python Script<\/H2>Here is the Python script we will use:<\/P> <\/P> <\/P>from arcgis.gis import GIS
from arcgis.mapping import WebMap

gis = GIS(username='<developer>')

webmap_items = gis.content.search(query="type:'Web Map'")

for webmap_item in webmap_items:
webmap = WebMap(webmap_item)
map_area_items = webmap.offline_areas.list()
for map_area_item in map_area_items:
header = f"'{webmap_item.title}' has an offline map area named '{map_area_item.title}' sharing the 'Area2Package' relationship with:"
print(header)
for rel_item in map_area_item.related_items('Area2Package', 'forward'):
print(f'\t{rel_item.title}\n\t\t{gis.url}\/home\/item.html?id={rel_item.id}\n\t\t{rel_item.type}')
print('\n')<\/code><\/pre>'Bonn WebMap' has an offline map area named 'Bonn WebMap_MapArea' sharing the 'Area2Package' relationship with: Vector-8795e9d21ed7456c90e332c7a363bfdd https:\/\/<organization>.maps.arcgis.com\/home\/item.html?id=422affa753fc4a378f9dea691d5f3047 Vector Tile Package<\/code><\/pre> <\/P> <\/P>Script Explanation<\/H2>This script iterates through all web maps and lists for each map all offline map areas and their related portal items. The 'Area2Package' relationship indicates that the map area was exported as a package for offline use. The related portal items were created as packages from the map areas.<\/P>Conclusion<\/H2>ArcGIS API for Python enables the automation of complex tasks such as listing offline map areas and their related portal items. With a little Python, we can leverage this API to make our work with ArcGIS more efficient and effective.<\/P>I hope this blog post was helpful!
