Hi to all Georg maybe your should also ask in the pywps mailing list. I don't have any GRASS examples "at hand". In the wiki there's just some small notes concerning openlayers http://wiki.rsg.pml.ac.uk/pywps/OpenLayers Maybe in a few weeks I'll have something, again better to ask in the pywps mailing list Jorge On 15/08/11 12:06, Saber Razmjooei wrote: > http://pywps.wald.intevation.org/documentation/process.html > > We are working on some demos.

Re: [GRASS-user] Rainfall interpolation for a time series
Hi Hanlie, I've this before with 11 gauge stations, also using TRMM data. You'll probably want to write a script and use r.mask to mask the interpolation map to your grid cell, then do r.sum on your masked area. After that just divide by the area to get the average rainfall. Given the small area and limited number of gauges this shouldn't take very long to compute for 2 years of data. You should be able to fairly easily output your desired time series to a text file.

[GRASS-user] Rainfall interpolation for a time series
Hi, I have rainfall measurements from 6 gauges that I want to interpolate to an areal value (a 'surface'), so that I can compare the the interpolated gauge values to a satellite rainfall estimate that covers a grid cell of 28kmx28km. Two of the gauges are outside, but close to the border of the grid cell. Therefore, I also need to clip the interpolated surface to the grid cell and to get the average of the surface value in this clipped surface. A search on Google revealed that v.vol.rst is probably a good choice for interpolating the rainfall because it takes elevation into account. However, for each rain gauge I have 730 values representing a daily measurement over two years. As output from GRASS, I need a text file with the interpolated rainfall values for each day in my time series. So, I was wondering if there is an 'easy' way to get my output without creating 730 vectors and rasters?
