Processing Steps
- Images were obtained from [GloVis]
- Once the images were imported into ArcMap, they were georeferenced by hand using distinct features in the landscape
- After being placed in approximately the appropriate location, the images were rectified and the borders of images were clipped using the "Extract by Mask" tool and a polygon shapefile
- The extracted images were added to the ArcMap project and used to create the final product
Alternate versions
- None
