When I uploaded my maxent output file in ArcMap (it's in ASCII format, a distribution map of a country) it showed me the the spatial reference is unknown. I will create binary maps later (suitable, unsuitable habitat) and calculate the area. So I have to make the file ultimately in a UTM coordinate since its unit in meters. I'm confused which approach of the following is accurate, shall I use Define Projection tool to define it to WGS84 (DD unit) first -which is the original coordinate system of the data I entered into maxent- then use Project tool to change to a projected coordinate system (UTM, meters unit)? Or I can immediately from the define tool choose a UTM coordinate?
If the first approach is the accurate one. I did tried it but when I reach the project tool step it doesn't recognize the file in the input. I tried exporting the file to a tiff the same issue. When I saved the file as a layer (*lyr) it did recognize it but showed me this: ERROR 000840 The value is not a Feature Layer. ERROR 000840: The value is not a Feature Dataset.
