The Overpass API is a read-only API that provides specially selected sections of OSM map data. It is possible to visualize the selected data on the map with the Overpass API menu in the BlueGIS.

Step 1: Overpass API

The overpass API panel can be accessed via the ‘Overpass API’ option in the "Data Library" on the left menu.

Step 2: Overpass API Panel

The layer name to be registered is entered in the Overpass API panel. The layer will appear with this name in the layer box. After naming the layer, the data requested to filter will be selected.

NOTE: Any number of filters can be added, but a bigger data size will cause failure.
