Hi, I’m the Summer of Code participant. My name is Jan Jezek and I’m working on project focused on improvement for coordinate systems transformations. The project is mentored by Jesse Eicher. The new tools to be implemented are: -Transformations parameters calculator – the tool for calculating the transformation parameters for several transformation methods (affine, linear, position vector or bursa wolf =7 parameter transformation, bilinear interpolated triangulation). Parameters should be calculated from coordinates of identical point specified by user (using least square Method for errors between target points and source points after transformation).
- Transform tool – the tool to apply calculated transformation. - Rubber Sheet Transformation– The new mathematical transformation that can convert one data file to another with zero deltas on identical points. These functions should be added into the geotools at first and after that there will be uDig plugin developed. Nowadays the RubberSheet transformation seems to be working. Because of this transformation there has been also delaunay triangulation implemented. The calculator for Affine and Bursa wolf transformation parameters is also almost done. The uDig transform plugin still needs to be done. The code can be seen here: http://svn.geotools.org/udig/community/jan/2.2.x/ext/transformations/ Cheers, Jan. ------------------------------------------------------------------------- Using Tomcat but need to do more?
