# Measures Functions
[Data Observatory Measures](/dataobservatory/overview/#measures-methods) allow you to access geospatial measures for analysis workflows. Measures are used by sending an identifier or a geometry (Point or Polygon) and receiving back a measure or absolute value for that location. Every measure contained in the [Data Catalog](https://cartodb.github.io/bigmetadata/observatory.pdf) can be accessed through the CartoDB Editor.
