To generate a grid that excludes tessellation features that do not intersect features in another dataset, use the Select Layer By Location tool to select output polygons that contain the source features, and use the Copy Features tool to make a permanent copy of the selected output features to a new feature class. For example, select all features in column A with GRID_ID like 'A-%', or select all features in row 1 with GRID_ID like '%-1'. This allows for easy selection of rows and columns using queries in the Select Layer By Attribute tool. The format for the IDs is A-1, A-2, B-1, B-2, and so on. The GRID_ID field provides a unique ID for each feature in the output feature class. The output features contain a GRID_ID field. This occurs because the edges of the tessellated grid will not always be straight lines, and gaps would be present if the grid was limited by the input extent. To ensure that the entire input extent is covered by the tessellated grid, the output features purposely extend beyond the input extent.
