Area

This node will add a new column named 'area' to the input data with the calculated area of each geometry in the units of the CRS. Area may be invalid for a geographic CRS using degrees as units. Use the Projection node to project geometries to a planar CRS before using this node. This operation is planar, i.e. the potential third dimension is not taken into account.

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

Options

Geometry column

Select the geometry column to compute the area.

Output

Group of settings that define the format of the result table.

Output column

Choose where to place the result column:

Available options:

  • Replace: Replace the selected input column with the result.
  • Append: Append a new column with the name provided below.
New column name

The name of the new column that is appended if 'Append' is selected.

Input Ports

Icon

Input table with a geospatial column to compute the 'area' for.

Output Ports

Icon

Geo input table with additional 'area' column containing the area of each input geometry in the units of the CRS.
