---------- Forwarded message ---------- From: [email protected] <[email protected]> Date: Sun, Jan 24, 2010 at 1:12 PM Subject: please help transform of coords for Prishtina DXF To: [email protected], [email protected], "PROJ.4 and general Projections Discussions" <[email protected]> I have here a dxf file of Prishtina in high quality. http://www.archive.org/details/PrishtinaStreets I have been able to convert it to lat/lon like this cs2cs +proj=utm +zone=34T +ellps=WGS84 +datum=WGS84 +units=m -f \"%.7f\" Problem is that most of the points are in relative position, there is a grid. I have pushed a version of two nickels that can process alot of this : To [email protected]:h4ck3rm1k3/TwoNickels.git c8e4009..41f23f1 master -> master It produces osm files with data in three groups : 1. points that are exact on the mark, (few) 2. points on the equator (0,0) relative to something 3. points that seem to be shifted over from utm34T 720496.25, 506444.9375 -> 22.987450699423831679, 4.5791053696411907481 I have created averages of good points versus the shifted ones and came up with these constant shifts: $n -= 187380; $e += 4228672; They are still 15km off of prishtina.. So I would like one of you to please help with the autocad and transform all coordinates into some single form so I can convert them. Or please advice on these points. thanks, mike
