naming Roads

Sean Burlington
The new key value stuff has immediately made it possible to produce
useful maps of my area :-)

Of course I now have some feature requests ...

Some roads have been put in that don't seem to relate well to the GPS
tracks -

presumably this is sometimes when they have been entered based on one
set of tracks only - and subsequent tracks have made the line clearer

but sometimes it just seems random - relating neither to the tracks nor
to my knowledge of the real roads.

Currently it's hard to decide what to do with these paths - it would be
easier if I could

* turn off the roads (or make them semi transparent)

* undo deletions if I make a mistake
(or add a save button so changes don't get made till I'm done)

Also some areas have been *very* well traversed by GPS carriers - and it
seems that the GPS tracks are only shown if there are less than 5000? of
them in the display area - this means that I can only see tracks if
zoomed in really close.

e.g. - no GPS tracks
http://www.openstreetmap.org/edit/edit-map.html?lat=51.52&lon=-0.05&scale=4e-05

* Would it be possible to show tracks at least for the central area when
editing

The Roadmap and Ideas pages on the wiki...
http://www.openstreetmap.org/wiki/index.php/Roadmap_For_Version_1.0

...states that there is no plan to include places of interest as
polygons - but there are a lot of routes shown that go through parks
(and there are parks that are almost covered in yellow GPS dots) - it
would make the map much clearer if these areas could be shown.

Finally - I was looking at OSMApplett which refers to

 processing.core.PApplet;
 processing.core.PImage;
 processing.core.PFont;

which I couldn't find - are these in svn?

good idea, added as a bug

http://www.openstreetmap.org/bugzilla/show_bug.cgi?id=44

This one is more tricky. On the one hand we want the applet to be as
simple as possible, on the other hand people want lots of functionality.
Maybe this is better as a JOSM feature?

5k or 50k points is the limit. Something like that. Simply because much
more takes far too long to render and ship to the browser.

I can up the limit. Again, this is a balance between different use
cases. How do the guys in Birmingham feel about it?

Sure, you'll be able to do this with polys

Yes, but they're wrapped up in core.jar which is nabbed directly from
processing. Tom knows more.

have fun,

I just thought it might be easy to store changes in the applet for a
while and 'save' to the server on request - if it's tricky it doesn't
matter that much.

Is there a quick way to get the number of tracks in a given area?

if so I was thinking there might be a way of getting speed and
functionality by showing tracks for the whole display if under 5000 -
then try again for a smaller area - and maybe trying again once or twise.

Part of the problem was that I didn't understand at first *why* no
tracks were appearing - some message might be useful.

I was looking for the source ...

When viewing these streets outside the java applet (I'm unable to use
the applet, long story), no street manes appear.  Should they appear
on

Yeah, just to clarify - Roadmap for Version 1.0 was our way to get the
project focused over the summer (and it's mostly done).  It doesn't
match up with the API version numbers - by the time those hit 1.0
you'd better hope there are polys in OpenStreetMap :)

Full subversion browser, bug tracking and javadocs are at
http://dev.processing.org - it's not a very java-y way of writing
Java, but some things are super easy. It's designed for teaching and
prototyping, the latter being why I used it.  Full list of functions
available inside PApplet is at http://www.processing.org/reference/

Current core.jar is from processing 0095.  Any particular questions,
just ask me, I'm reasonably familiar with the source and I don't want
to bother the Processing guys with OpenStreetMap problems unless it's
their bug (like one of the current problems with text entry is).

Tom.

Yes they should but I havn't written the code yet.

I'm more or less happy with the current limit. I can't speak for anyone
else of course.

I would love to be able to turn off specific tracks (ie don't draw
trackpoints from track-20051023.gpx.gz, or all tracks uploaded within a
date range). However that would complicate the applet somewhat.

In general, I log at a comparitively high rate (1 trkpt/sec). Does this
cause problems for anyone, or is a high rate preferred?

Alex

RE: naming Roads

ANDY ROBINSON-2
Sorry I missed the original request for a response from the Birmingham
contingent on this!

Personally I don't see the need to up the points limit. The majority of my
mapping like Alex's is done with 1 sec interval track points so we get a
swathe of yellow up close when editing. Yes it means there is not much track
to see when zoomed out (just the most recent segment) but that's irrelevant
when editing has to be done close in anyway for urban areas.

I still think we should be aiming, like Alex says, at having at least some
filtering or selection basis on track points. Otherwise the problem is only
going to get worse.

Just out of interest, what map scale are others editing at? I'm generally at

1.4e-05 for the residential streets and perhaps 2e-05 for the distance
routes. I guess perhaps with the greater node "snap" capability some are
editing farther out?, in which case the amount of points rendered may become
an issue.
