2 Geospatial databases need to stay in synchronization automatically to provide decision makers updated information for better decision in flooding emergency
situation. Different schema may be involved. The schema mapping needs to be done while the updating can be properly done.
3 Internet connections or wireless connections may be an issue during flooding disasters due to infrastructure damage. Inspections and update need to be better
supported with proper data management. Information needs to stay synchronized as fast as the available internetwireless connection allows if updating is required.
The solutions to these issues are respectively proposed and tested as follows. 1 Change request to the transaction service of WFS to support management of
imagery features as attributes to geographic feature. 2 Semantic matching and mapping of different schemas needs to be developed and
adopted to support fast and robust updating of geospatial databases. 3 GeoPackage is used to efficiently manage complex geospatial databases that
allow information to be better managed when offline. Synchronization of GeoPackages is developed and tested. The method for synchronization at the
GeoPackage level is found to be an efficient mechanism to support complex information maintenance.
