DIGITAL PHOTOGRAMMETRIC WORKSTATION

 DPS-DELTA

Provides creation and/or revision of digital maps and orthophotos from raster images.   The software support video modes from 1024x768HiColor to 1600x1200TrueColor and better.  The station provides a fixed cursor and scrollable images on a standard PC.

Hardware:

  • The photogrammetric station is based on a standard Intel-compatible computer working on Windows 98/ME/2000/XP system. The software supports video modes from 1024x768xHiColor to 1600x1200xTrueColor.

  • Can work with stereoscope (split screen mode) or OpenGL 3D-shutters (page flipping mode)

  • The station provides a fixed floating mark and scrollable images in split-screen mode; this functionality does not require any special hardware support.

  • Users can move the floating mark with a classic handwheels / footdisk combination and/or with the mouse.

  • Stereoscope or stereo shutter glasses can be used for observation.

Orientation program:

  • Provides management of camera and ground point lists

  • Semiautomatic orientation of single photos or stereo models

  • Full error control and correction on each orientation stage

  • Works with aerial and satellite images of central and panoramic projection

  • Imports absolute orientation elements from different formats

Mapping software:

  • Works both with stereo models and with single photos using a DEM

  • Data collection over a stereo model or single photo

  • Can be used for digitalization of orthophotos or scanned maps

  • Three-dimensional superimposition of vector data on raster images

  • Automatic and semiautomatic DEM extraction, building and interpolation of contourlines

  • Fully customized layers, symbols, object parameters and other map attributes

  • Collection using templates of standard object types, automatic creation and addition of polygons

  • Automatic snap to points/lines of existing objects in collection mode

  • Works with black-and-white and color raster images up to 4Gb large on standard computers

  • Supports popular vector formats: DXF+DBF, MID/MIF, ASCII

  • Online coordinate exchange with other programs via TCP/IP or COM-port.

DPS DELTA SOFTWARE

Supports full photogrammetric production started from triangulation / adjustment to final symbolized map/ortho output. Based on the Digitals mapping engine with stereo-plotting possibilities.  Allows to create nice-looking digital maps and orthophotos from areal or satellite images.  Works in stereo mode with stereoscope or OpenGL shutters, works in mono/mono+ mode without an additional hardware. Optionally uses handwheels/footdisk equipment:

 Orthophoto mosaicking:

  • Creation of mosaic from any number of arbitrary raster polygons located in different photographs

  • Automatic DEM extraction for orthophoto creation and building contourlines

  • DEM-grid editing using shutter glasses or stereoscope

  • Import of DEM data from ASCII text or DXF format as spot-heights and/or contours

  • Image correction can be done separately for different portions of image of any shape

  • Creation of raster/vector orthophoto maps with geodetic grid and legend using any fonts and symbols

  • Printing or saving maps into raster files

  • Possibility to enrich with cartographic symbols, color attributes, etc. digital maps created in other systems

  • Editable libraries of symbols of all types

  • Creating arbitrary types of frames and legends with automatic insertion them into maps

  • Creating different map templates

Automatic triangulation:

  • Contains own rigorous bundle adjustment engine BlockMSG for on-line adjustment and control;

  • Quick correlation algorithm for automatic point transfer;

  • Full quality control using correlation, parallaxes and tie-point errors;

  • Automatic and semiautomatic modes of measurement;

  • Filtering measured points using various criteria;

  • Convenient tools for block analysis and error detection, sorting models and points by any parameters.

  • Uses 3D-mode for accurate ground points measurements

Terrain related functions:

  • Creation of a regular DEM-grids and TINs based on spot-heights and/or contour lines

  • Building contour-lines using DEM or a TIN

  • Contour-line interpolation

  • Assign of height to every map object according to spot-heights and contour-lines

  • Creation of profiles and sections, volume calculation

Other mapping functions:

  • Operates both with stereo models and with single photos (using DEM)

  • Three-dimensional superimposition of vector data on raster images

  • Can be used for vectorization of orthophots and scanned maps

  • Allows to customize layers, symbols, object parameters and other map attributes

  • Uses templates of standard objects types to simplify data collecting

  • The panel of favorite most used layers

  • Automatic 2D/3D snap at points and lines with indication

  • Automatic and semi-automatic DEM extraction, building and interpolation of contour-lines

  • Raster maps and photos in TIFF (including JPEG and ZIP compressed), RAW, JPEG and BMP formats can be used

  • Operates with huge black-and-white and color raster images on a standard computer

  • Supports popular vector formats: DXF+DBF, Shape, DGN, MID/MIF, ASCII, etc.

  • Real-time coordinates exchange with other programs via TCP/IP, OLE and COM-port.
