Rapidly Making Colorful Landsat-8 Imagery Composite with Free Advanced Image Stretching and Pan-sharpening Software from GeoSage - See more at: http://www.gisuser.com/content/view/30197/2/#sthash.36sxzlnJ.dpuf
The TatukGIS Editor version 4 has been released with features to rectify, georeference, and mosaic 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.
TatukGIS PixelStore (SQL) format support for huge raster mosaics.
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 control points to perform nonlinear transformations to correct more complex distortions. An Editor 4 product update will add an alternative “rubber sheeting” rectification method that uses an unlimited number of control points to perform the rectification calculation.
The Editor 4 upgrade is available for free to customers with active license maintenance. A trial version for evaluators is available from the TatukGIS web site.
The TatukGIS Editor is a general purpose desktop GIS application and is both powerful and user friendly. The default user interface and features are fully customizable with built-in scripting tools which expose an extensive object API.
