What are polygon grids? (Production Mapping)

This topic applies to ArcGIS for Desktop Advanced only.

Polygon grids are grids that are created over a specified extent and stored in a polygon feature class. The grid divides the specified extent into cells so that you can systematically review a large dataset. In the polygon grid, individual grid cells are polygon features that can be attributed and selected. This type of grid can be used with applications such as Data Reviewer to divide large extents into more manageable sections and define areas of interest for map series.

These grids can be used during Reviewer sessions to manage both visual and automated quality control. With Data Reviewer, the polygon grid can be associated with the Reviewer table and the grid information associated with individual records. Cells that contain features that have been recorded as records in the Reviewer table have the QC_GRID field populated with polygon grid information.

There are three major steps when creating a polygon grid:
