We use Collector to gather data on trees on our land. As well as the tree information collected there are various other layers to provide contextual information to the field worker. These contextual layers, which are supplied by third parties, need be available office, which means they need sync functionality and I believe this means they need Global IDs.
The issue I have is that these datasets are from third parties and are updated. This is done by truncating the table and adding the new data in resulting in new Global IDs being created. When Collector next syncs, will it just remove all the features and add the new ones back in, or will it add the offline data to the data in our database, or something different? We find Collector quite unstable with syncing anyway so don't want to do anything that would make this worse!
