Plugin Offline Editing

For data collection, it is a common situation to work with a laptop or a cell phone offline in the field. Upon returning to the network, the changes need to be synchronized with the master datasource (e.g., a PostGIS database). If several persons are working simultaneously on the same datasets, it is difficult to merge the edits by hand, even if people don’t change the same features.

The offlineEditingCopyOffline Editing Plugin automates the synchronisation by copying the content of a datasource (usually PostGIS or WFS-T) to a SpatiaLite database and storing the offline edits to dedicated tables. After being connected to the network again, it is possible to apply the offline edits to the master dataset.

Utilizzo del plugin

  • Open some vector layers (e.g., from a PostGIS or WFS-T datasource).
  • Save it as a project.
  • Go to Database ‣ Offline Editing ‣ offlineEditingCopyConvert to offline project and select the layers to save. The content of the layers is saved to SpatiaLite tables.
  • Modificare il layer in modalità non in linea.

  • After being connected again, upload the changes using Database ‣ Offline Editing ‣ offlineEditingSync Synchronize.
