TatukGIS Editor 4 with Raster/Vector Layer Rectification

Gdynia, Poland
June 06, 2012

The TatukGIS Editor version 4 has been released with features for rectifying, georeferencing, and mosaicing raster and vector map layers. The vector support is ideal for rectifying CAD drawings (with an unknown coordinate system) to a selected coordinate system or correcting old vector layers to match a new orthophoto.
  • Rectification is performed on-the-fly (similar to on-the-fly reprojection of map layers between coordinate systems), so the rectified result is instantaneously visible.
  • Rectification reflects the Editor's state-of-the-art coordinate system support with 3,000 pre-defined coordinate systems.
  • The rectification/georeferencing/mosaicing functionality can be customized with scripts, such as to create labor saving routines for repetitive procedures.
The rectification calculation reflects 1st, 2nd, and 3rd order polynomial transformations. The 1st order transformation uses information from 3 ground control points to scale and rotate the layer. The 2nd and 3rd order transformations use information from 6 or 10 ground control points to perform nonlinear transformations to correct more complex distortions. An Editor 4 product update will later add an alternative “rubber sheeting” rectification method.

The Editor 4 upgrade is available for free to customers with active license maintenance. Other Editor customers may renew their license maintenance via the Shop/My Shop page of the TatukGIS web site. An Editor 4 trial version download is available for evaluators.

Customers of the now discontinued TatukGIS Aerial Imagery Corrector (AIC) product may cross-upgrade to the Editor as explained in AIC Merged into the TatukGIS Editor. The cross-upgrade offer expires August 31, 2012.
