SPOT High Resolution Visible and Near Infrared Image Data from SSC Satellitbildin Kiruna, Sweden

The high resolution sensor HRV operates in two modes: panchromatic (0.51-0.73
micrometer) with 10 meter resolution and multispectral (0.50-0.59, 0.61-0.68,
and 0.79-0.89 micrometer) with 20 meter resolution. Each scene is normally
60x60 km.

More than 700 000 SPOT images (over 100 000 per year) from all parts of the
world are archived at SSC Satellitbild. About 40% of the total number is from
the onboard recorder of the satellite.
The ratio between multispectral and panchromatic data is 40/60.
Approximately 3000 scenes per year are processed and equally many films
produced.

The different processing levels include various radiometric and geometric
corrections, precision correction using group control points, with or without
digital terrain model, and output in any standard map projection.

The data is produced as digital data or as a variety of photographic products.
A unique product at Satellitbild is the Satellite Image Map which, as a
complement to the scene format, is imagery in map sheet format. Another product
is digital terrain models from SPOT data.

The most common digital distribution media is magnetic tape at 1600 or 6250 bpi.
The production system is able to read and produce all of the most frequently
used formats for satellite imagery, i.e. CRIS-format, SPOT IMAGE-format,
LTWG-format, FAST-format, ERDAS-format, etc.

For input to ARC/INFO GIS system, the GISIMAGE format is available. GISIMAGE
is an ERDAS image format delivered on 1/4 inch cassettes or CCTs for input
on both SUN and VAX stations. The GISIMAGE is ideal as a background image for
integrated raster/vector updating of map information.
