I have files with the u resp v components of regularly spaced wind vectors (ASCII arrays). How can I construct flow vectors.
There is no direct ASCII grid reader in the IDV, but it is on our list of things to do. The big problem is deciding on a format. The underlying VisAD library has a method for reading ASCII grids and we are looking at using that as well as a netCDF-Java IOSP. There are a couple of options: - use the VisAD text reader and then try to display the resulting data structure using the Any Field formula and selecting a flow display. - use the GEON-IDV ASCII->netCDF converter described at: http://geon.unavco.org/unavco/IDV_for_GEON_data_converters.html Stu Wier might want to chime in on this since he's the one who developed it. Can you send a sample file to support-idv? Don ************************************************************* Don Murray UCAR Unidata Program dmurray@xxxxxxxxxxxxxxxx P.O.
