Flexible data import for McIDAS-V
The primary mechanisms used in McIDAS-V to import satellite data are through the VisAD file adapters and McIDAS-X Abstract Data Distribution Environment (ADDE) servers, which retrieve data from remote servers or local files. This works well for specific data types and file formats for which servers or file adapters have been written. To address more generic formats, two areas are being investigated:
1. The ability to read in flat files (binary or text) and picture files (for example, GIF and JPEG) and assigning geolocation through a projection specification or tables of latitude/longitude. ENVI or McIDAS-X AXFORM header files facilitates the ease of importing the data.
2. The use of Unidata's network Common Data Form (netCDF) version 4 along with netCDF Markup Language (NcML) files to more easily handle a variety of Hierarchical Data Format (HDF) version 4 and 5 files. This is being applied to simulated imager and sounder data for the upcoming National Polar-orbiting Operational Environmental Satellite System (NPOESS) mission.
The status of these efforts and future plans will be presented.
