PHOTOMOD software family comprises a wide range of products for photogrammetric processing of the remote
sensing data which allow to extract geometrically accurate spatial information from almost any commercially
available type of imagery obtained either with film or digital cameras, high resolution satellite scanners or
synthetic aperture radars.
The first license of PHOTOMOD was sold in 1995.
Since that time the system has
been continually improved to adopt the requirements and wishes of customers. It has thus evolved from a set of
tools for a single stereo pair processing to a complete digital photogrammetric system able to produce all
significant kinds of photogrammetric data such as DTMs, orthomosaics and vector maps.
All necessary
photogrammetric operations such as block triangulation and adjustment, automatic creation and manual editing of
DTMs, 2D and 3D feature extraction, orthorectification and mosaicking can be implemented within a uniform
PHOTOMOD software environment without utilizing of any third party products.
At the same time special
modules StereoLink and StereoVectOr can be used to help the users to work seamlessly with
MicroStation.
While most of PHOTOMOD users still apply it to process aerial images, the number of clients
utilizing satellite images in their projects is steadily increasing.
When processing satellite images,
rigorous sensors’ models are applied where it is possible (SPOT, ASTER, EROS, Cartosat-2) or RPC (QuickBird,
IKONOS, OrbView, Cartosat-1). If such information is unavailable more general Direct Linear Transformation
(DLT) algorithm is used.
The presentation describes also the newest improvements in PHOTOMOD 4.2 including
advanced capabilities of satellite scanner imagery processing and support of airborne digital cameras data.
