How to make raster background transparent in AGO map viewer
We have some drone imagery in TIFF format that we published to Enterprise from Pro and then shared to ArcGIS Online through a distributed collaboration. In the map viewer, the zero-value areas around the periphery of the drone imagery display as solid black areas.
In Pro, we can make the map display the zero values in the raster as transparent so that we can see the underlying basemap. Is it possible to do this in ArcGIS Online as well?
Thanks in advance!
Hi Judith,
Adding the raster to the map, displaying zero values as transparent, and then publishing it to Enterprise from the table of contents in Pro works (right click on image layer > Sharing > Share as web layer). You would choose the Tile option under "Copy all data," as suggested above by @Katie_Clark (see screenshot below). In the configuration tab of the Share as Web Layer pane, I've been having good results selecting the ArcGIS Online/Bing Maps/Google Maps tiling scheme and then adjusting the level of detail to meet my needs.
Note that the publishing may be fairly quick, but building the tile cache can take a long time. Don't judge your final result until that tile cache building process is complete. Good luck!
