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
, and 3rd
order polynomial transformations. The 1st
order transformation uses information from 3 ground control points to scale and rotate the layer. The 2nd
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.
