I am relatively new to ArcGIS, and am creating a map for the water/sewer utility that I work for. I have a geodatabase created, but need to add my raster. This map is going on our Windows mobile device that does not have internet access, so I can't just use a Basemap from ESRI. I have 120 individual mosaic Sid tiles that I would like to add. What would be the best way to go about this? I didn't know if I should create a raster dataset with the toolbox, or create a layer package from the Table of Contents... or something completely different.
