Photogrammetry

Key Features

Allows collection areas to be user-definable and range in size from an entire stereo model to any smaller portion of the stereo model defined by the user
Defines geomorphic features, such as breaklines, ridge lines, drain lines, vertical faults, and elevation points, in a feature table to any level, color, weight, and line style
Allows planimetric features that also represent geomorphic changes in the terrain, such as drainage, retaining walls, and road edges, to be input into ISDC and used as geomorphic features
Handles arcs, curves, and line fillets as breaklines
Performs DTM collection from stereo satellite imagery
Checks Z ranges of DTM points
Full model modification and manipulation, and fence editing, as well as feature tag and attribute editing
Allows the user to select areas where no DTM collection or contour generation is desired by using an obscure area definition
Excludes zones, such as defined buildings or areas of tree canopy, from being correlated by ImageStation Automatic Elevation (ISAE)
Allows the user to view contours over the collected area while still in the model, using on-line triangle and contour generation
Shows the user the effect of edits in real-time by the dynamic editing of triangles and contours
Allows for overlay ISAE batch DTM extraction on the stereo model for editing and the detection of trouble areas
Includes a queue processor to drive the user to suspect points detected by ISAE
Imports and exports various DTM file types into ISDC
