ucar.nc2.iosp.dmsp.DMSPiosp
public class DMSPiosp
This ucar.nc2.iosp.IOServiceProvider provides access to DMSP satellite data in the NOAA/NGDC DMSP archive format. Currently only data from the OLS instrument is supported, in particular only NOAA/NGDC DMSP OIS (OLS Integrated Smooth) data files. The OIS data is visible and thermal imagery at 2.7km resolution. The DMSP satellites are polar orbiting satellites crossing the equator, depending on the satellite, at either dawn/dusk or noon/midnight. More information is available at http://dmsp.ngdc.noaa.gov/.
