As part of my work at Technical University of Budapest, I developed the website of Department of Geodesy. Within that site, I've started a section for free GIS software.
Available software research and text writing, simple HTML.

about me
Exisitng editors for text data DjVu files are quite limited, like for example DjVuSmooth. So I've implemented a new editor in JavaScript, that allows editing both the strucutre of the text (paragraphs, lines, words,...) and the coordinates of the text boxes by simply dragging with the mouse, features like create, delete, merge are also available.
