Hello Tim, I agree with Jukka on the topic. (Open-)Jump is measureless, which means it simply shows/projects the values (x,y) in the window. It does not know about projections how to interpret a specific measurement. I wrote an extension which reprojects coordinates of data. But still _you_ have to know what the original cs is, because Jump does not know a way to find out.
Solution: Reproject the Shapefile (the data must hold the new coordinates) before you edit it in Jump. Or. Try to reproject in Jump. Whether use the mentioned extension or a connection to GIS enabled DBMS and reproject use the dbms capabilities. Extensions to load/save data from/to a dbms are available. Both options might proof more difficult than use your commercial GIS software for the purpose. Regards ede -- > Hi, > > I wonder why OpenJUMP shows you lat/long coordinates.
