I need to export a ESRI basemap (or anyone with high resolution) image as a raster to perform a posterior classification. I need to differentiate trees from ground soil to obtain the proportion and use it as L factor in the Soil Adapted Vegetation Index. I wanna do it because I am working with Sentinel-2 data and it will be a great improvement to calculate VI.
I know that it is possible to do that by the export map option and save it as a jpg. The problem is that the extent of my study area gives me an output with low resolution doing the previous process. And the image is not georeferenced as well.
It is possible to export high resolution basemap imagery in a georeferenced format using ArcGIS Desktop 10.5.1?
