Save FLO-2D Project

Save FLO-2D Project#

In the current FLO-2D Plugin version, the QGIS Project file (*.qgz) is saved inside the GeoPackage. This new method has many advantages in terms of portability, styling the symbology, and reducing potential path errors. It is also allowed to save external user layers to the GeoPackage.

Save a new FLO-2D Project#

  1. Click this button to save the FLO-2D Project.

Note

This save method is different from the New and Open FLO-2D Project buttons. This is the native QGIS save button, located at the top left of QGIS.

  1. If no error was found and no external layers were added to the project, the following message will appear on QGIS toolbar showing that the project was correctly saved.

  1. Select Yes will open the GeoPackage Manager. To protect a layer and keep it with the project. Move the layer to the left window. This will commit the layer to the geopackage and disconnect it from the external file.

  2. If the layer is only needed once consider keeping it on the right side and then remove it from the project once it is no longer required.

  3. Things like Google Maps, Server Connected Layers, MapCrafter Layers are not allowed on the left. Leave them on the right.

  1. If No is selected, all layers will be saved as paths. If this method is used and a project is moved to another location or computer, the file paths must be reconnected and the external files may need to be moved too.

  2. Layers such as Google Maps, MapCrafter layers will not become part of the GeoPackage. They will be saved to the QGZ system.

The current version only supports vectors and rasters to be saved to the geopackage. CSV files and basemaps are not allowed. If a basemap or other file is loaded, it may still be able to save in the QGZ storage table that is packaged in the GeoPackage.
