Edit Features in a Geospatial Feature Source
Connect to geospatial feature sources to display the features in your map. You can then check out a feature, edit its geometry and data, and check it back in to update the feature source with your changes.
NoteThe coordinate system
for the map will automatically match your database. You don't need
to assign a coordinate system to the map itself, unless you want
to transform the data to a different coordinate system. Generally,
you should edit in the same coordinate system as your database.
If the data is in different coordinate systems, edit one layer at
a time so you are always editing in a coordinate system that matches
your data.
