How can I load a geopackage (.gpkg) file from the portal into ESRI's ArcGis 10.x software?
A Geopackage (.gpkg) file is a SQLite database, which allows storing and sharing spatial, vector and raster data. This facilitates the distribution of geographic information in an open and standardized format.
ArcGIS 10.X (including ArcMap and ArcCatalog) recognizes GeoPackage files as if they were geodatabases, which means that it is possible to access, view and work with the layers contained in a .gpkg file in a similar way to other ArcGIS-compatible geospatial formats.
However, ArcGIS 10.X does not support special characters in layer names, such as accents, the letter "ñ" or symbols. If the GeoPackage file contains layers with names that include these characters, the layer names must be modified before attempting to load the layers for display.
