I wanted to say thanks very much to Jim Potemra and Isilda da Cunha Menezes for their help and patience with the station plotting problem I was having.<br><br>However, the solution has not created another issue. It appears as though the largest radius of influence you can use is 50; what are the units on that by the way? The data I have is somewhat sparse though so I end up with little circles contoured and a good amount of empty space. Is there any way to change the maximum radius, or anything else for that matter, so that the entire area of interest can be shaded/contoured without having to modify the source code?
<br><br>I did find the spot in the source code (gafunc.c) to increase the maximum radius however I seem to be having issues building GrADS from the source (without any modifications) results in the error below. Anyone have any ideas on either issue?:

Hello Matt!<br>You must have the ctl file that specifie the stations data, you should<br>also have a binary file of an unitary grid that cover the whole area of<br>the stations and a ctl where it specifies this grid. Attention that the
<br>date from both ctls has to be the same ones. After running the command<br>stnmap (I use the stnmap -1) you should open both ctls in the grads and<br>not to forget defining "set dfile 2" for the open file in second place.
<br>Then display the data with the command oacres( grid variable, stations<br>variable).<br><br>Best regards<br>Isilda<br><br><br><br>> Good Afternoon,<br>><br>> I am attempting to convert station data into gridded such that it can be
<br>> contoured and not just appear as regular station plots but I am not quite<br>> sure how to do that. I already have my data in a grads readable format<br>> and<br>> can display it as a station model, however I seem to be having some

<br>> how<br>> to deal with this. Do we have to have another file open that contains<br>> gridded data that GrADS will interpolate to? I have attached the sample<br>> station data file I am working with in case it might help; I am looking to
