Step 1: Add New Layer
The results of the Overpass API query are added to an active layer on the map. Therefore, a new layer must be created.
Note: You can easily create the layer with the quick layer creation button.
Step 2: Services 🡪 Overpass API
The Overpass API is a read-only API that provides specially selected sections of OSM map data.
The data selected via the "Overpass API" menu in GISLayer can be visualized on the map.
Click the Overpass API button on the Services tab.
NOTE: The Overpass API query is performed within the boundaries of the map displayed on the screen. Zoom in on the map where you want to get information. To get results, the map scale should be 1:500 in meters or more.
Step 3: Overpass Query Panel
There are 3 options in the Overpass query panel.
- The layer on which the query is to be saved must be selected.
- The query to be applied must be selected.
- If you want to add additional queries, this option should be checked. (Described in Section 3.2.)
