Hi, cs2cs is a part of proj http://trac.osgeo.org/proj/ Transforms from one projection to another.
I think it's just a matter of getting the projection parameters right. Maybe this tool can help you, I just googled it (via http://gis.stackexchange.com/questions/7608/shapefile-prj-to-postgis-srid-lookup-table): http://prj2epsg.org/search kind regards Jørn-Vegard Røsnes ----- Original Message ----- > From: "Murat Beyhan" <bey...@deprem.gov.tr> > To: "Jørn Vegard Røsnes" <j...@spacetec.no> > Cc: "mapserver-users" <mapserver-users@lists.osgeo.org> > Sent: Monday, 21 May, 2012 9:57:53 AM > Subject: Re: [mapserver-users] convert projection from UTM to WGS84 using proj > > > Hi, > > is cs2cs a tool for converting shape data and > are there any example for this purpose > actually I added +x_0=500000. to ogr2ogr command but doesn't cahaged > the > result :( > > > On Fri, 2012-05-18 at 14:00 +0200, Jørn Vegard Røsnes wrote: > > Hi, > > > > I lost your previous email, so this is just by memory. > > I'm not an projection expert, but here we go :-) > > > > Regarding 3dg offset: > > In your .prj file there is an false easting=500000, so maybe it > > helps adding +x_0=500000. > > http://proj.maptools.org/gen_parms.html > > Se also +towgs84 in the same link and .prj file, and adjust > > accordingly. > > > > Maybe a shot in the dark because 3dg = 333958,33m (40 075,017km / > > 360dg). > > I think you're near the solution. > > > > See also > > http://spatialreference.org/ > > http://spatialreference.org/ref/epsg/4230/ > > > > kind regards > > Jørn-Vegard Røsnes > > > > ----- Original Message ----- > > > From: "Jørn Vegard Røsnes" <j...@spacetec.no> > > > To: "Murat Beyhan" <bey...@deprem.gov.tr> > > > Cc: "mapserver-users" <mapserver-users@lists.osgeo.org> > > > Sent: Wednesday, 16 May, 2012 11:21:22 AM > > > Subject: Re: [mapserver-users] convert projection from UTM to > > > WGS84 using proj > > > > > > Hi, > > > maybe something like this: > > > > > > ogr2ogr -s_srs epsg:4230 -t_srs epsg:4326 <dest shapefile> > > > <source > > > shapefile> > > > > > > http://www.gdal.org/ogr2ogr.html > > > > > > kind regards > > > Jørn-Vegard Røsnes > > > > > > ----- Original Message ----- > > > > From: "Murat Beyhan" <bey...@deprem.gov.tr> > > > > To: "mapserver-users" <mapserver-users@lists.osgeo.org> > > > > Sent: Wednesday, 16 May, 2012 10:41:39 AM > > > > Subject: [mapserver-users] convert projection from UTM to WGS84 > > > > using proj > > > > > > > > Dear friends, > > > > I'm sorry, I'm not good at GIS applications but I wondering > > > > about > > > > conversion between various projection or datum of the data > > > > files. > > > > > > > > data.shp data.shx data.dbf and data.prj files are available. > > > > > > > > shpdump data.shp gives following > > > > > > > > Shape:0 (ArcZ) nVertices=4, nParts=1 > > > > Bounds:( 513275.786, 4006041.761, 0, 0) > > > > to ( 513345.812, 4006078.182, 0, 0) > > > > ( 513275.786, 4006078.182, 0, 0) Ring > > > > ( 513301.130, 4006064.906, 0, 0) > > > > ( 513321.636, 4006053.249, 0, 0) > > > > ( 513345.812, 4006041.761, 0, 0) > > > > ... > > > > > > > > > > > > > > > > > > > > > > > > data.prj as follows > > > > > > > > PROJCS["(UTM)Universal Transvers Merkator 3�",GEOGCS["EUROPEAN > > > > 1950",DATUM["European_Datum_1950",SPHEROID["International",6378388.00000000,297.00000000], > > > > TOWGS84[-87.00000000,-98.00000000,-121.00000000,0.00000000,0.00000000,0.00000000,0.00000000]], > > > > PRIMEM["Greenwich",0.00000000],UNIT["Degree",0.01745329],AUTHORITY["EPSG","4230"]],PROJECTION["TRANSVERSE_MERCATOR"], > > > > PARAMETER["SCALE_FACTOR",1.00000000],PARAMETER["CENTRAL_MERIDIAN",36.00000000],PARAMETER["LATITUDE_OF_ORIGIN",0.00000000], > > > > PARAMETER["FALSE_EASTING",500000.00000000],PARAMETER["FALSE_NORTHING",0.00000000],UNIT["meter",1.00000000]] > > > > > > > > > > > > using these data How to convert a file which is created using > > > > european_datum_1950 to WGS84 (World Geodetic System 1984) > > > > or where I have to start to understand these method of > > > > applications > > > > using PROJ4. > > > > Thanks > > > > muratB > > > > > > > > > > > > -- > > > > This message has been scanned for viruses and > > > > dangerous content by MailScanner, and is > > > > believed to be clean. > > > > > > > > _______________________________________________ > > > > mapserver-users mailing list > > > > mapserver-users@lists.osgeo.org > > > > http://lists.osgeo.org/mailman/listinfo/mapserver-users > > > > > > > > > > > CONFIDENTIALITY > > This e-mail and any attachment contain KONGSBERG information which > > may be > > proprietary, confidential or subject to export regulations, and is > > only meant > > for the intended recipient(s).
