The dialog finds the layer, I click 'Add', the layer appears in the table of contents, although there appear to be no features (e.g. adding the layer through 'Add Data from ArcGIS Online'.adding the GeoService url (full and many shortened versions) through both 'Add ArcGIS Server' and 'Add WMS Server' in 'Add Data'.I have seen other ArcGIS Open Data pages that also include a url in the API section for OGC WMS ( example), so it may be a conscious decision to not serve data in a format consumable by ArcMap, but I'm not familiar enough with web service protocols to be certain. Is there any way to consume the data from either a GeoJSON or GeoService API url from an ArcGIS Open Data Portal page, into ArcMap (using v. Is there documentation regarding this 'trick', or can someone explain why this works? It is 1.1-1.3x lighter in file size compared to shapefiles.EDIT: I was able to add the layer in the example below by using the GeoService url, removing 'rest/', after much trial and error. Geopackages are lightweight and compatible across environments specially in mobile devices.A Geopackage stores both raster and vector files whereas, shapefiles can store only vector files.A shapefile can handle maximum size of 2 GB and cannot export a vector layer with more features. In a geopackage, there is no limit on the file size and can handle large number of features in a smaller file size.Several tools and websites let you view and create maps, perform analysis and download our spatial data.GIS ResourcesMap DirectThis public mapping application lets anyone create, print and share custom maps with DEP program data. Geopackages run faster on algorithm outputs compared to shapefiles. The departments mapping and spatial data library are managed through Geographic Information Systems (GIS).A shapefile can only have 10 characters to define the column header. Compared to shapefiles, the column headers in a geopackage can be full names and right by providing the correct context for each column.Whereas, Geopackages includes all the information of the layer in a file and is easier to transfer or share. Sharing a shapefile with someone would be complicated as all the other files attached will also have to be shared. vices in the disaster management domain and present a suitable Geo Web Service. Shapefile is a multi-file format with minimum of 3 files and several other attached files with different extensions. better real-time collaborative post-disaster management tools are needed.Why choose Geopackages and not Shapefiles?
