[mapserver-users] GPS to GIS
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.

Re: [mapserver-users] GPS to GIS
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.

Re: [mapserver-users] GPS to GIS
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.

[mapserver-users] GPS to GIS
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!

Re: [mapserver-users] GPS to GIS
I've used GPSBabel (http://www.gpsbabel.org) to download data from my GPS and get them into more usable formats. It can also convert between formats. I'm not sure what you mean by converting between GPS and GIS coordinates. If you have a delimited table of coordinates you should be able to import it into a GIS to create, for example, a shapefile.

RE: [mapserver-users] GPS to GIS
I think that the way that you phrased your questions was a little confusing. 'GPS coordinates' and 'GIS coordinates' are really the same thing. It sounds more like you want to convert the format that the coordinates are stored in from the one used by your GPS to one that works in a GIS or with MapServer. I hacked up a python function to read .gpx files. I will send it to you off-list. You could then use it in conjunction with the OGR python module to write a shape file.

My intension was to convert CPS-coords to GIS-coords on the fly and for that purpose I needed a piece of scripting (an algorithm). But if GPSBabel can convert data between these formats, I'll go for that.
