A long time ago I used a tutorial for the community basemap to create vegetation polygons from lasdsat ir data. I'm trying to repeat the process but the old tutorial links no longer work. Is there a wy to access this info still? The old link was help.arcgis.com/en/communitybasemap/10.0/help/index.html#/Vegetation/01010000000m000000/
I've seen this article How to Create NDVI Maps in ArcGIS - GIS Geography but was unable to download imagery from the usgs that had nir band. I also found the ndvi data on arcgis online but cant figure out how to get the bands to just display 1 or -1 which I think is step then turn in to a grid then polygon... does anyone else remember this process?
