ISTAR (Imagerie STereo Appliquee au Relief or, in english, Stereo
Imagery Applied to Relief) is a company specialising ... in DEM production
by automatic correlation techniques. It makes use of aerial
photographs or satellite imagery and markets two products ranges,
namely AERIAL and SPOT. The DEM-derived products include orthoimages,
area features by automatic extraction, linear features by
semi-automatic extraction, computed contours lines and image maps.
DEM production may also be based on digitized contour maps.
Since 1986, ISTAR has produced a total area of 1 million sq.km. from
SPOT images at different resolutions (typical pixel size: 40m for XS,
20m for PA; typical Z standard deviation: 1/2 pixel).
ISTAR can meet very large capacity requirements (1 to 20 GB) of
complex databases including standard components (DEMs, Orthoimages,
Land Cover and Vectors Files, Scanned Maps) at different scales and
formats. All products and their references are contained in a price
list and are described in technical documentation.
