I wrote a short item about raster rectification issues a month ago. The projective method mentioned at the very end of the article was designated as problematic in Autodesk Raster Design environment so I took some time to clear theoretical things behind that (since I work with Agisoft Photoscan for some time). pokračuj / entry »

The goal of this short entry is to throw some light on one peculiar part of terrain stratification units, namely the structure (and more specifically “the wall”). pokračuj / entry »
AutoCAD Raster Design – raster rectification overview
May 12th, 2013 komentáre: 1
Among other interesting functions, AutoCAD Raster Design has some possibilities to rectify raster images through well-known function Rubbersheet that enables two basic methods of rectification (triangular and polynomial). As far as I remember from my photogrammetry courses there are also other methods to do these things and there is general misunderstanding of theoretical background of two above mentioned as well. So the question is:
- how do these methods work; what are they useful for?
- where do they belong in the wide field of raster data processing?
Videotutoriál – tlač v AutoCADe

Krátky videotutoriál k bazálnej tlači v prostredí AutoCADu. Pozdravujem Tibora Lieskovského a ospravedlnenie – spomenul som si na našu debatu v septembri až teraz, takže postujem s polročným oneskorením…
ArcGIS Desktop – polygónová topológia z jednoduchých línií
October 11th, 2012 komentáre: 0
Vytvorenie polygonov z hraničných čiar je jednoduchou záležitosťou. Je žiadané hlavne vtedy, keď potrebujem polygonovú topológiu, ale samotné kreslenie je výhodnejšie realizovať bázickými linkami. pokračuj / entry »
