get latitude and longitude for every point in a path

[Naumanpak]

Experts,

I am working on tracking and navigation.


I want to get latitude and longitude after every 10-15 meters for a path.

Since its going to hard roaming entire city getting points with a GPS, I need suggestions on how to get latitude and longitude from google maps for every point.

When I move cursor on google earth, I can see the Lats and long changing at the bottom. Obviously, its going to be much harder noting them out.

I need to know if there is a simpler way.


Need help....

thanks

Maths is not my strong point, but if it is a straight path, could you not fine the start and end lat/long then divide the difference by how many points you need. I am probably missing something here, just a thought. Also some maps like aviation charts are marked round the edges with positions and you would just draw an intersecting line, not sure about smaller scale maps for this, maybe worth checking.

Hm.. looks like the right way to start

Should be OK for straight paths but I roads are messy out here.

Isn't there any tool that can extract data files from google earth?



thank you GrandAlf!

You should certainly be able to mathmatically derive data for straight line or great circle navigation. But as to following winding roads, I cannot see any real way of doing it other that zooming in and taking readings every so often or drivig the rout and storing the track like you can in some GPS'es. Also I cannot think any sort of tools could help you unless later versions of autoroute show lat/long, I know it can be interfaced to GPS though. Sorry I cannot be more helpful, a bit out of my field here.

GrandAlf, I have tried one thing and it may turn worthy.

I added paths on google earth by taking points, one click and one reading for lat and long.


Saved the path as .kml and then was able to retrieve lats and long for the points.

Still tough though but useful..

helped!

thanks again for reviewing!
cheers
