Merging GRID files in ArcMap

Introduction
This procedure outlines steps to merge Digital Elevation Model data into a single file using ArcMap 9.1. The following steps assume the raw data has been prepared to the point of being functional within the ArcMap environment. If there are issues opening the digital elevation data, please see the various procedures available from http://www.brocku.ca/maplibrary/procedures/procedures.htm This procedure uses DEM data from the Ministry of Natural Resources.

Step One: Adding data to a View

Step Two: Working with Spatial Analyst

Step Four: Customizing the DEM Properties

To view a DEM in 3D you must use ArcScene. Follow the directions outlined at http://www.brocku.ca/maplibrary/procedures/3d_view/3dview.htm
