Buffer

This node generates a buffer with the given distance for each geometric object.

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

Options

Geometry column

Select the geometry column to use.

Distance

The buffer distance for the input geometry.

Distance unit

Choose the distance unit to use.

Available options:

  • Use unit from input CRS: Do not re-project but use the unit of the input CRS.
  • Meter: Use the default projection with meter as unit. The projection is the UTM CRS for the UTM zone in which the centroid of the input geometries lies. This projection works well for most latitudes but may not work for some extreme northern locations like Svalbard or far northern Norway in which case you might want to use your own projection prior using this node.
  • Kilometer: Use the default projection with kilometer as unit. The projection is the UTM CRS for the UTM zone in which the centroid of the input geometries lies. This projection works well for most latitudes but may not work for some extreme northern locations like Svalbard or far northern Norway in which case you might want to use your own projection prior using this node.
  • Miles: Use the default projection with miles as unit. The projection is the UTM CRS for the UTM zone in which the centroid of the input geometries lies. This projection works well for most latitudes but may not work for some extreme northern locations like Svalbard or far northern Norway in which case you might want to use your own projection prior using this node.
  • Degree: Use the epsg:4326 with degree as unit.
Keep CRS from input table

If checked the CRS of the input table is retained even if a re-projection was necessary for the selected distance unit.

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

Table with geometry column.

Output Ports

Icon

Table with transformed geodata
