What is the primary purpose of "Field Calculations" in ArcGIS Pro?

The primary purpose of "Field Calculations" in ArcGIS Pro is to automate data entry or manipulate existing values. This feature allows users to perform calculations on attribute values within a dataset, which is essential for various tasks in GIS analysis.

Field calculations can be applied to update multiple records simultaneously, enabling users to efficiently manage data. For instance, if you need to calculate the area of polygons from their shape geometry, you can automate this process rather than entering values manually for each feature. Additionally, you can use expressions to derive new values based on existing field data, allowing for dynamic adjustments to your datasets.

Field calculations streamline the editing process, ensure consistency, and significantly save time for GIS professionals when managing and analyzing spatial information.
