Most people around openstreetmap are software / geography people, so |
21 |
they mostly use what's readilly awailable (GPS loggers, JavaME phones |
22 |
some time ago, smartphones now). I've seen hardware projects on the |
23 |
level "how to make a bike holder for XYZ" or "how to get a PDA and |
24 |
logger work together and with a large battery". There's a hardware page |
25 |
on the wiki [1] (if you haven't found it already), but it seem pretty |
26 |
outdated. As osm is opensource centered, there are/were people playing |
27 |
with open hardware / technologies stuff (openmoko phones, beagle/panda |
28 |
board with a gps receiver etc...) |
29 |
|
30 |
There's also a foss-gps mailing list [2], though IIRC there are mostly |
31 |
software guys who talk about how to work with lower level GPS data. |

There are basically two distinct activities in OSM: the collection of |
39 |
GPS logs/tracks and then the creation of the map/database itself based |
40 |
either on those logs or any other freely available sources. For land |
41 |
based information the elevation doesn't really get entered into the |
42 |
database, mostly because it would be realy sparse and there is SRTM data |
43 |
that's much better. I remeber some talk about an initiative to somehow |
44 |
process the elevation data from the logs, but I'm not sure where it |
45 |
ended. |
46 |
|
47 |
Anyway I guess it would be different for marine data, which might be |
48 |
more usefull... I guess you have to get in contact with people from |
49 |
openstreet map interested in that. The OpenSeaMap page on osm wiki [3] |
50 |
mentions even some mailing lists... |
