Asset Synchronization from GIS is Version Based

Ongoing data synchronization of GIS features into the system relies on Esri’s Geodatabase versioning capability. The latter allows for various long-running edits and designs to use designated copies of the data concurrently with the current default version.

The ongoing data synchronization process leverages this capability as follows:

  • The current default version represents features as built.

  • Initially, all eligible features in the default version are synchronized into the system and a “WAM” version is created to represent the already synchronized version of the data.

  • The next ongoing synchronization process compares between the default version and the “WAM” version to detect delta changes made in the default version since the last synchronization.

  • The result of the comparison is a list of previously synchronized features that were since deleted or updated as well as newly added features that are eligible for synchronization.

  • Based on this list, new assets are added to the system and changes are applied to corresponding existing assets using the predefined GIS to WAM Sync Mapping rules.

  • With each ongoing synchronization process a new “WAM” version is created to represent the most recently synchronized version of the data.
