# Extract from geo column[¶](https://doc.dataiku.com/dss/latest/preparation/processors/geo-info-extractor.html#extract-from-geo-column "Permalink to this headline")

This processor extracts data from a geometry column.

Extracts:

* Centroid point

* Length (if input is not a point)

* Area (if input is a polygon)

Warning: Length and area are expressed in the unit of the CRS, so often in degrees instead of meters.
