Count Objects

Counts the number of vector objects.


A processing block that computes the number of geometry features and geometry types (Point, LineString, Polygon etc.) extracted by other processing blocks such as:

See this block on the marketplace.

How it works

This block has no configurable JSON parameters.

The output is a JSON file count_objects.json containing the number of occurrences per geometry type:

[Counter({'LineString': 2621, 'Polygon': 46}), Counter({'Polygon': 5, 'MultiPolygon': 1}), Counter({'Polygon': 4087, 'MultiPolygon': 93})]
