Using ArcGIS 10, I have a Feature Class which I converted from a Raster (GRID) (Raster To Polygon Tool).
- There are approx. 180,000 polygons.
- The attribute table contains a [grid_code] field which I need to preserve.
- If one or more polygons are contiguous with corners touching AND they have the same [grid_code] value, then I'd like to group them (a dissolve basically) into one polygon (record).
- Then I need to calculate the grouped polygon's area.
Using the Select By Location Tool, I'm able to successfully select the polygons that I need to group, but how do I then convert them into ONE polygon, while preserving the [grid_code] ?
