Hello,
I want to make a map using the Bobolink abundance raster data downloaded from eBird (https://science.ebird.org/en/status-and-trends/species/boboli/abundance-map?week=1&season=breeding). I was able to download this file as a .tif and upload it to ArcGIS Pro (3.5.3). However, I am having trouble projecting this data into the correct coordinate system and cannot figure out what coordinate system I should use. My map is in WGS 1984 Web Mercator (auxiliary sphere). When I upload the file, I get an unknown coordinate system warning, and the file is clearly not in the same projection as the map (see screenshot). I have tried to define the coordinate system and project raster tools, but since I do not know the original coordinate system, these tools do not solve the problem. How do I determine what coordinate system to use?
I am not terribly familiar with managing coordinate systems or with using raster data, so any advice is appreciated.
Thank you in advance!
Anna
