Join Adam Wilbert for an in-depth discussion in this video Merging rasters, part of ArcGIS Essential Training.
- Because of their increased file size…over vector datasets, raster imagery…often only covers a limited bit of ground.…Typically, lots of separate files will be needed…in order to cover an area of interest.…In the United States, a common system…is to split the raster data up according to…USGS topographic map quadrants…that cover the entire country.…For a very high-resolution data,…these areas can even be split into…four smaller zones, called quarter quadrants.…After finding the quadrants that cover your study area,…you might want to merge them back together again…in order to make it easier to work with them in ArcMap.…Here, inside of ArcMap,…I've started a new Blank Map Document.…
I've also pinned the Catalog window open.…Let's go ahead and browse into our Folder Connections…under ExerciseFiles, Chapter_09,…and Chapter_09 Data.…Inside of that, we'll find our Digital Elevation Models.…Let's go ahead and drag one of these into our new map.…Now, if you're prompted to build pyramids,…go ahead and just say Yes to that window.…
