[OSM-talk] Easy to use system for countryside surveying

[Gert Gremmen]

The phones with built in GPS have 
inferior performance to a GPS mouse.
This is VERY visible in town, and visible
outside towns. 

I use a N81 with whereami and a BT mouse
 currently ,this is the only solution that comes close 
to your proposal
with good track accuracy (and not by averaging)
and enough reliability to survive more
then 5 minutes ( 3-4 hours is no problem)
without crash. I have tried most available solutions
but none functions reliable. 
Phones with built-in
GPS will do nice in a autoroute application but will
Fail dramatically in accuracy if you have to actually draw roads.


I have bad experiences with N95 E90 (nokia) and HP 6500 series.

Onderwerp: [OSM-talk] Easy to use system for countryside surveying

Hello everyone,

Have thought of an approach to make countryside OSM mapping using phones

with inbuilt GPS (N95, etc) easy to the end user.

A user could survey their walk using an N95 or similar, and then, using
a 
very simple interface, select whether they are on a footpath, bridleway,

unclassified road, track, etc every time the type of path or road they
are 
on changes. So if they're on a road, then turn off down a footpath, they

could select "footpath". Then if the footpath merges into a bridleway, 
they could select "bridleway".  The result would be a GPS track with 
sections "tagged" with footpath, bridleway etc.

A track simplification algorithm could be applied and ways generated
from 
the GPS trace automiatically. This could then be uploaded to OSM for a 
more expert user (who could subscribe to an RSS feed to inform them of 
such uploads in their area) to refine the way, i.e. remove extraneous 
points and connect the auto-generated way to existing ways.

Any thoughts?

Nick
