I'm having trouble creating a station-based rainfall distribution (grid codes)dfs2 or (polygons)shape file to give input for 'precipitation rate' in climate parameters. I have rainfall series data for different stations in excel format. I tried converting it into dfs0 time series format, but I wasn't able to do so. Fed up with that issue, I have created a new dfs0 file myself using my data. Now, how do I convert this dfs0 into dfs2 file format, so that I can give it as input for station-based (grid codes)dfs2 file. If not, how to create a (polygons)shp file for my input? Please help me.
