matrix of distance between points with ecological barriers and other parameters

Discussion created by cecilen2 on Apr 11, 2013
Dear all,

I'm trying for several days now to do something on ArcGIS that seems very very simple in theory but I do not succeed.
here is my problem:
I have a shape file with points representing the location of animals. I want to have a matrix of distance between all my points. However, I also don't want to have an simple euclidean distance, I need this distance to be weighted according to ecological parameters. For instance, the animals will be less likely to climb mountains, will not cross rivers etc... With these parameters, I have make a "cost raster".
I would therefore need to have a distance matrix between all points that takes into account the landscape and this costs raster that I have made.
So far I have tried the "distance between points", but there is no cost raster that can be used. OD would be interesting but I do not need any network as my animal can go where they want, etc...
I hope I am clear enough!
Thanks a lot for anyone that can help
