I am working on or should say struggling to create new data layers for
environmental variable to run MaxEnt.
I am using both ArcPro and ArcMap 10.8.
Neither seem to be able to create the necessary grid files needed.
None of the "tool Box" tools seem to work for this.
I have polygons that are distances from key ecologically important
features. These include caves, water bodies and rivers.
All distance SHP files were created by buffering the features in 200 m
increments from 0 to 10 km.
When trying to convert to any raster format TIF or GRD the conversions
either fail or display only a single 10 km distance.
I have not tried converting from SHP polys to ASCII directly, not even
sure that works.
All climate and altitude data as well as the to "habitat" layers which
are categorical data have worked fine.
However the distances are key predictor variables I need to include.
Species data is all parsed and fine.
I will then need to convert the resulting prediction maps from MaxEnt to
SHP files to create maps for my new book
Any suggestions welcome.
