[Openstreetmap] Re: Attributes gathering, saving data

Thu Apr 7 16:05:10 BST 2005

You will find if you build a large database you may
want to re-import data due to conflation errors so you
should save everything. The attributes you decide to
keep is based on the type of map you want to produce.
All topography has a value to some-one, which does
your project consider to be of primary importance?
Routable streets if you are focused on vehicular
navigation I suppose. Destination points and landmarks
for destination routing would then also be of
importance eventually. Do you plan to include lkes,
rivers and coastlines? Then you may want to hand
vectorize from ortho rectified imagery as well. land
designation would fit more with polygon modeling.
Traffic direction can  
be critical for routing. A desktop cam with a good
sony type chip out the window can be good for
capturing exit and routing signage that may be too
dense to dictate to tape. 
Hope that wasn't overly repetetive.
The question I had is how do I view my data that I
uploaded online to update the file or add new
attribution or edit my/your tracks?
