Generate and overlay a pre-defined grid with a raster

Discussion created by sblsbrm2 on Jun 27, 2012

I have a raster with a resolution for 30 m and pre-defined grid coordinates. I had two questions: -
1. How can i generate a grid if I have the projection, origin, number of rows and columns and size of a grid? I have used the Coordinate System option in main data frame properties window where I can define the projection, datum and grid size but not the number of rows and columns.
2. How can I overlay this grid with the raster? I have to compute number of units of different elements in the grid.
