[mapserver-users] GPS to GIS

2008-08-07 Thread Peter Falk 

Hi David,

Yes I know i was a bit vague. What I need is a simple function, that can turn a 
point in GPS - a lattitude and a logitude value - into a point in GIS.

I.e. I got these coordinate:
GPS: N: 54.9809  E: 8.86707

that applies to

GIS: X: 491055.41Y: 6092507.928

What I need is the correlation between the two.

Regards
Peter

Hi Guys,

Thanks for your input. It's been a great help. The fact that I'm now 
aware of the translation - from WGS84 to UTM Zone 32 - has narrowed the 
problem down.

Hi Peter,

What do you mean with 'GIS' coordinates ?

For me, GIS means Geographic Information System and is a very common 
term.
Looking at your 'GIS' coordinates I would say that your GIS coordinate 
system is a UTM 32 coordinate system.


And in your case, you could use cs2cs 
(http://proj.maptools.org/man_cs2cs.html) in order to make the 
translation.


cs2cs.exe +proj=latlong +datum=WGS84 +to +proj=utm +zone=32 
+datum=WGS84 -r

input : 54.9808N 8.86707E
output : 491492.61   6092662.95 0.00

The results are not exactly accurate with yours but they are close 
enough to me (by what ? 600 meters ? ^^).


I hope it will help.

Regards,
Benoît Andrieu

[mapserver-users] GPS to GIS

2008-08-06 Thread Peter Falk 

Hi,

I have a table of GPS-coordinates that I want to use as POI. I've tried 
to find an algoritm to convert GPS-coordinates to GIS-coordinates but 
without luck.


It would be a great help if anyone could tell me how to do this 
translation. Thanks!
