Non-DSS data can be provided to HEC-MetVue in a variety of formats. These include ESRI ASCII, NetCDF, GRIB, and GeoTIFF. Regardless of the input file format, Non-DSS data is assumed to have a single image per file (see NCGribExtractor for handling NetCDF/GRIB files with multiple images per file). This assumption allows for a generalized Non-DSS Data Selector, and Reading by Drag and Drop.
