Using the Ortho Mapping tool in ArcGIS pro is very easy and effective if you have some geotagged drone data! I show you how to use the basic features of the Ortho Mapping module with a subset of data over Heron Reef. The quality of the resultant mosaic is incredible! If you would like to try it out using some sample data, check out http://www.geonadir.com/ and you can download from there
