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.

Il plugin offline_editing_copy Offline Editing permette di automatizzare l’attività di sincronizzazione, copiando il contenuto della banca dati principale (solitamente un database PostGIS o un WFS-T) in un database Spatialite e memorizzando le modifiche non in linea in tabelle dedicate: le modifiche, poi, vengono sincronizzate una volta riconnessi alla rete.

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 ‣ offline_editing_copyConvert 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 ‣ offline_editing_sync Synchronize.
