Hi, In order to show your imagery and vectors together you must reproject either of them, that's clear. Also, JUMP cannot do reprojection for you but you need to use external tools. It may be possible to reproject PostGIS data directly into JUMP, but I have not ever tried it. But it might be worth trying what happens if you use "Run database query" option and feed that with a query like: SELECT transform(geom, 4326) from my_table_in_Lambert
If that does not work you can create a new table inside PostGIS using SRID 4326 with a query and read that new table to JUMP above your image. But if you want to keep your vector data in the original projection you must reproject the image. There are good free tools for that, for example gdalwarp if you prefer command line, or OSSIM if you like interactive application better. -Jukka Rahkonen- -----Alkuperäinen viesti----- Lähettäjä: [EMAIL PROTECTED] puolesta: Stefan Steiniger Lähetetty: to 3.4.2008 19:02 Vastaanottaja: JUMP Users Discussion Aihe: Re: [jump-users] Adding Tiff -- displays fine, can't project/ overlayon vector data from Postgis Hei, ok.. if you have a world file Jump should do the transformations as far as the coordinate systems of your shape files and raster files are in the same system (i.e. both in Lambert). What it does not do is a real transformation between coordinate systems. But As far as I know twf files do not have information on the projection (e.g. Lambert, UTM, ...) only on their position within the system. Does it look better in QGIS?
