Level 1b HRPT/LAC is high resolution (1 km) data which can be obtained via the World Wide Web. The Level 1b designation indicates that this data is an enhanced form of raw HRPT data. Level 1b data contains extra information such as Earth location values in lat/long. This Earth location data is used to form a grid of up to 255 GCPs, which are stored in a GCP segment when FIMPORT is applied to Level 1b data. FIMPORT will also create a text segment which contains information such as the satellite name, date/time of image capture, orbital (ephemeris) element values, and some calibration data.
For the Level 1b HRPT/LAC format, FIMPORT also creates a binary orbit segment containing per-scanline quality, calibration, and timing information.
