Transform from local to WGS84 howto

Aug 2, 2008 at 11:30 PM
Hi all,

what is the fastest way to transform points from Belge 1972 or Netherlands RD New to WGS84?

EPSG 31300 to 4326
EPSG 28992 to 4326

My dataset is a local coordinate polygon shapefile which i'd like to store as WKT in WGS84.

Also, I understood that on the fly rendering goes fine, but when using vertices it is still in the original coordinatesystem.

Hope anyone can help me out here,...

Hi, I have same problem transform from my personalized proyection to UTM, I only change the proyection with Oracle (I think is posible with PostGis but not try too), Oracle change "really" the values from yoou proyection. After you can "save as" with a software like Kosmos or gvSIG to use this data on a ShapeFile. I try to change every coordinate with program but can´t write to SHP file after modify the data.

Thanks for the info.

However that is not an option in my case as the data is from user input too.

I hope anyone has some info on this matter,...?
