I have a script that allows me to process a text file of latitude longitudes (stations) and I'm trying to output area averages of a particular file based on the points generated from the text file.<br>
<br>
I'm basically calculating the grid point spatially associated with a specific station.
<br>
<br>
So far it works to give me the x1, x2, y1, y2 but I can't make it loop over all the points for area average of the gridded file.<br>
<br>
My version of grads: Config: v2.0.a9.oga.1 little-endian readline printim grib2 netcdf hdf4-sds hdf5 opendap-grids,stn athena geotiff shapefile<br>
<br>
Here is the script (some of the material is likely obsolete as I got the code from an earlier project):<br>
<br>
function main(arg)<br>
<br>
file = subwrd(arg,1)<br>
size = subwrd(arg,2)<br>
color = subwrd(arg,3)<br>
<br>
record = read(file)<br>
<br>
record = sublin(record,2)<br>
<br>
i = 0<br>
<br>
counter = record<br>
<br>
while(i < counter)<br>
<br>
record = read(file)<br>
<br>
record = sublin(record,2)<br>
<br>
ilat0 = subwrd(record,2)<br>
ilon0 = subwrd(record,1)<br>
ilon1 = subwrd(record,3)<br>
ilat1 = subwrd(record,4)<br>
<br>
<br>
*say ilon0 ilat0 ilon1 ilat1<br>
<br>
linia(ilat0,ilon0,ilon1,ilat1,size,color)<br>
<br>
i = i + 1<br>
<br>
endwhile<br>
<br>
return<br>
<br>
function linia(lon0,lat0,lon1,lat1,size,color)<br>
