Description
Expected behaviour
Resulted isochrone geometries could be ordered by isochrone_distance (in descending our). This would benefit the user as the largest isochrone geometries (the most far-reaching isochrones) would stay below the smaller ones (the isochrone geometries with the smallest time-based or road-based distance to the destinations). This would be expected behaviour:
Current behaviour
The current behaviour visualizes the geometries as follows:
Additional context
To see the expected output, first, you have to export the output layer generated by the Catchment plugin as a GeoPackage or to a new GeoPackage. This enables you to run SQL and order the geometries by the isochrone_distance-column. In QGIS, you can execute SQL on your GeoPackage-files e.g. as follows:
Modify accordingly (layer name) the following SQL query and execute the query:
SELECT * FROM "zones_30_min" ORDER BY isochrone_distance DESC
Without any transparency and visualized in a graduated (by the isochrone_distance-column) mode, the output visualization would be the following:
