Powerful Imaging Software

Take a look at the powerful imaging software utilised by Survey Graphics. Survey Graphics are the exclusive agents for the Geo-system DPS softcopy suite of products in Australia, Indonesia and the Pacific Region.

Deltascan Colour Photogrammetric Scanner Software

The scanning software package is a set of applications working in windows 9x/2000/XP on an Intel-compatible computer. The software supports scanning both colour and black-and-white films at various resolutions. Quick pre-scan computes an image histogram and then automatically suggests the optimal settings for further scanning: exposition, contrast and gamma for every colour channel.

Users can set scanning parameters manually by clicking on a summary histogram or histogram of any colour channel. The software immediately reflects the changes on the image. The program can compute histograms of areas defined by the user and perform image correction, based on these histograms.

Software Capabilities

Automatic detecting the optimal scan settings for whole film or specified images
Manual adjustments of scanning parameters and transformation tables for each separate channel
Scanning in tiled TIFF (with or without JPEG), plain TIFF, RAW and BMP formats
Density linear mode provides maximum detailing and uniform distribution of image intensity
Scanning positive and negative films in direct and mirror modes
The use of digital filters when scanning to reduce the noise of the image
Geometric calibration and accuracy control by measuring scanned control grid plate
Improved radiometric calibration and dust and scratch removal.
Masking of colour channels and saving colour channels in separate files
Optional automatic creation of zoom pyramid for every scanned image
Logging every scanning process allows users to view settings of previous scans and restore if necessary.

Post-processing software capabilities

Image analysis with histograms
Image correction by applying a selection of filters to groups of raster files.
Re-sampling images to any pixel size
Merging/splitting colour channels from/into separate files
Fast processing raster files up to 4GB in size.

Mapping and Cartography Software

The mapping software is designed for creation/revision of topographic maps as well as special purpose maps, such as urban cadastre and land management schemes.

Detailed & Accurate

Multimedia maps containing vector, raster and OLE data.
Support for high resolution satellite images and orthophotos.
Unlimited list of layers that define the appearance of objects; line and fill attributes, associated cartographic symbols and other properties.
Automatic and semi automatic DEM extraction.
Editable libraries that contain ordinal, linear, linear-orientated, linear-scaleable and areal symbols.
WYSIWYG mode: the map is displayed on the screen just as it will be output to a printer, plotter or bmp file.
Saving maps along with its attributes in a single file.
Processing of stereo or single photos
Automatic and semi automatic DEM extraction
3D superimposition of vector data on raster images
Fully customised layers, symbols, object parameters and map attributes

Multi-document interface with support for standard copy, cut and paste operations; within a window or between multiple windows. Abilities include group selection/search of objects by any combination of parameters and performing any operations on the all selected objects. Possibility to enrich digital maps created in other systems with cartographic symbols, colour attributes, etc. Support for DXF+DBF, DGN, Shape, MID/MIF, ASCII, etc formats. Creation of arbitrary frames and legends, with automatic insertion of them into the maps. Creation and usage of different map templates.

Orthophoto Mosaic

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

Automatic DEM extraction for orthophoto processing and building of contours.

DEM-grid editing using shutter glasses or stereoscope viewing systems. Import of DEM data from ASCII text or DXF format as spot-heights and/or contours; Image correction can be processed individually for any shape of any portion of a single image.

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

Printing or saving maps into raster files.
Able to enrich with cartographic symbols and colour attributes of digital maps created in other systems.
Compilation of map borders and legends with automatic insertion into completed maps.
Compilation of varied map templates.
