Caution: When editing the geometry in a third party tool like QGIS, theocbase will not be aware of the changes when cloud syncing. In order to upload the changes you need to mark the territories as edited e.g. add a blank in the remark field. In QGIS you can also export the territories into a KML file and import this file in theocbase.
territories: for viewing and analizing the territories
Add the layers by clicking on the OK button.
