Hi Laurent
For one cave in the Dordogne, I used cs UTM31
The co-ordinates to fix the entrance were then read off from a UTM grid
overlay on the digital (CD) version of the IGN map
You may find this site helps http://www.geoportail.gouv.fr/accueil,
though I seem to only be getting lat-Long or L
You need to know the coordinate system you are using, then maybe these links
will help

Hi all,
I try to put my cave centerline on google maps, I generated the kml
file without issue.
But I don't know the espg code for google maps, I tried a lot of them,
but I'm always on the sea, I try to convert to an other system, always

For example my
When I did this in the UK most of the time we do not use the full
co-ordinates, just the final few. So to get over this I had to use
calibrate [ ]
