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?
