Dissolve

This node aggregate geometries based on group id (string column) and only keep the two column with GeoDataFrame.dissolve, which only dissolve geometries here. For grouping attribute values of other than geometry, the GroupBy node in KNIME is a complementary tool.

The node is based on the GeoPandas project and uses the following related information and function:

• GeoDataFrame.dissolve

Input ports

1. Type: Table
   Geo table

   Table with geometry column.

Output ports

1. Type: Table
   Transformed geo table

   Table with transformed geometry column.
