Questions and ideas that might help:
How dense is your point data-set? What is the spatial resolution your
aiming at? Could latitude be your criterion in eliminating (somehow)
points? It's an important factor in estimating solar irradiation.
Maybe take ideas from existing maps (10km seems to be a high
resolution value for solar irradiance mapping).
Thanks, Nikos.
We are trying to model habitat for a plant species that appears to
prefer particular slope positions, often in steep ravines. So we need a
very high resolution to capture shading from surrounding topography.
20m-sq cells is the resolution of our DEM, and biologically we can't use
a coarser resolution. The data set is fairly dense, such that I can't
see any obvious ways to simply block out areas within the larger map. I
may try the scripting approach that Vaclav suggested instead.
Best,
Tyler
