Folks:
I would LOVE to see someone take over development on starspan -- I
did submit a OSGEO application but it came back denied, more or less,
because of lack of community support. There are a lot of bugs and user
interface issues still remaining that would be nice to get cleaned up,
but I'm not a C programmer and, while I developed the algorithm itself,
I was not the coder.
If anyone is interested in working on the development, please email
me! If you all are not sure what STARSPAN does, it is a flexible way to
get raster data (raw or summarized) associated with vector coverages
(similar to Arc's zonalstats, although with more output types). E.g.,
if you want to get the average pixel values from a SET of raster images
underlying a single vector coverage, starspan will spit out a CSV
containing the vector's original database, along with a column for the
average pixel value for that polygon. The algorithm tends to be very
fast, especially in cases where the polygon coverage is a fraction of
the raster coverage (which tends to be the case in many problems).

Jonathan + all,
please excuse my ignorance if I ask something that I shouldn't: could
you imagine starspan as part of GRASS? Something like "v.starspan" ?
