DIVA-GIS

Good Afternoon,

I am currently working on a model of an invasive species that is primarily limited to the banks of rivers/lakes/streams/etc. I was curious if there was a way that I could use climate data and known occurrences to create an niche model that will more or less buffer these hydrological areas, rather than the blanket out?

I know I could do this in Arc, using masks and transparent layers to isolate the waterways, but I am having an issue projecting the grid file.

Any advice on how to do this in DIVA?

Thanks in advance.
