I'm sure I've read a thread somewhere on PPrune about a little app that converts GPS/map co-ords, but can I find it ? It was a freebie written by a bloke that does many GPS related aplpets.
Anybody any idea where I've seen it ?
Cheers,
Giz

Not an App, but this site might help.

This (http://www.russ-hore.co.uk/osgb/index.php)will convert OSGB to Lat Long, any use

Many thanks for the responses chaps, but the sites mentioned are not what I found previously. In fact, I'm not even looking for myself, it's for a mate, and I promised him I could point him in the right direction...:ugh:
Best I keep looking...

What are you/your mate trying to convert from-to.
do a search for oziexplorer, a maping program. it will accept co-ords in one method, and by dhanging the config setting will display in another.

If it's British National grid to lat/long and vice versa, try:
National GPS Network - Coordinate transformer (http://gps.ordnancesurvey.co.uk/convert.asp)
...and more:
OSNet - spreadsheet for coordinate calculations (http://www.ordnancesurvey.co.uk/oswebsite/gps/osnetfreeservices/furtherinfo/spreadsheet.html)
Key question: convert what to what?
I wrote an Excel routine some years ago to translate NGR to Lat/Long and vice-versa. Happy to provide a copy.
Or is this GPS Lat/Long to "conventional" Lat/Long?

Conventional lat/long to decimal lat/long and vice-versa.

Convert Latitude / Longitude in Degrees/Minutes/Seconds to/from Decimal (FCC) USA (http://www.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html)

The US National Geospatial-Intelligence Agency (NGA) probably produces the world-wide gold standard for coordinate transformations. Software - GEOTRANS 2.4.2 available here -

Probably best not to rely on transformation software from someone who dabbles with coordinate software - you may find yourself somewhere you don't want to be!
Also, if you are converting ellipsoidal GPS coords into geodetic lat/longs be aware that some software does not work properly and may have errors of 100meters plus.
Good luck, Tanimbar
