Hi
I am new to ArcGIS so please forgive my ignorance.
I believe my problem is quite simple. I have a land cover raster (Corine, 100m pixel), and I have created a Species Richness raster (number of vascular plant species) , w/ same pixel and extent as the land cover raster, based on local data. Now I would like to investigate on the relationship between land cover and number of species. My questions:
a) is there a way to make some sort of spatial join, so that I would know the land cover type AND species richness for EACH pixel?
So I would have a table like:
ROWID | VALUE(LandCover) | VALUE (SppRichness)
b) or must I convert all this to vector in order to make such a join?
c) or, better yet, is there another way to get the comparison I'm looking for between the rasters? My idea is to try and find some sort of correlation - ideally, an average number of species richness per land cover type (a good estimate, with standard deviation).
Thanks in advance

Check the Combine Tool in the Spatial Analyst extension assuming you have it and your data meets the conditions
