Hi,<br>
<br>
I'm fairly new to postgis and spatial databases but have been very
pleased with the results I'm getting from postgis to date. One of my
projects is using postgis to load weather data from a 0.5 x 0.5 degree
lat/long grid. I'm looking to interpolate data values that fall
between that grid point I have values for. A bit of googling has
revealed a number of applications that interface to postgis and can do
what I need (eg GRASS), but I don't need their full functionality or
the overhead of interfacing with them. My project needs simply to
return interpolated values to a web page and I would rather just have a
pl/pgsql procedure that gives me interpolated values for a given point.
My initial thoughts are to feed the necessary point data from my
database into a custom pl/R function and get R to interpolate the data
for my point. However, that is going to involve a fair amount of
custom code and for me to learn more about R. I don't want to reinvent
the wheel, so I'd be grateful for any thoughts on solutions that meet
my needs?<br>

PS In my googling I also saw references to PGRaster, but it looks like
that's still under consideration for development in postgis?
