I apologize in advance if this is posted to the wrong section of the forum, please migrate as needed- this is my first post, I'm a long-time lurker.
I'm working on calculating exponential distance decay from a source input raster. I already have a Euclidean Distance raster with a maximum distance of 100 meters that I generated using that source input raster. Using this raster as my input, and applying a "resistance value" (of 6 in this case), the value should diminish from 6 (at the source raster) to 0 (at 100 m) . The formula that I've determined to do this for linear distance decay is:
((100 - "input_raster")/ 100)*6
Question: How I can I modify this formula for exponential distance decay- that is, to decrease exponentially from the maximum value (6) at the source, to the minimum value (0) at 100 m?
Thank you in advance for the input!
