I have two different datasets: 1) seal occurence (point data) 2) fishing boat tracks (line data)
First, I need to create two density maps, i.e. one for each dataset. For the seal map, I want each cell on my output raster to be assigned a value 0-1 according to the probability of occurence of seals in this cell. I tried Kernel Density but it didn't give me probabilities. Any idea of what I should do?? For the fishing effort map, it is exactly the same question.
Second, as soon as I manage to create my probability map for seal data, I will need to test for the overlap between fishing effort and probability of seal occurence. To do this, I need each cell of my output raster to be given a value based on the following equation:
with the values in the denominator being the sum of all the cells accross my study area,i.e. all cells of the raster.
