Re: [HOT] Experienced road network mappers - Salima District, Malawi

The problem with using imagery is it depends when it was taken.  Just after
the rainy season all the unpaved highways will be narrower. Realistically
if we map the highways connecting settlements as something such as
highway=unclassified surface unpaved then let the locals clean up that
probably is the best.

Re: [HOT] Experienced road network mappers - Salima District, Malawi

Hi all,

Just to follow up, here's a MapCSS file:
https://github.com/bjohas/JOSM-MapCSS-styles

The readme describes the colour codes used. For example, it adjusts the
style for residential, so that it's distinct from unclassified. Colouring
is added depending on surface, or for missing surface.

Hope it's useful!

Re: [HOT] Experienced road network mappers - Salima District, Malawi

Hi Rebecca,

Thanks for posting this!

A few suggestions below - let me say up front that I am really happy to
work on these together with others - but I think it does need a steer from
others as well, maybe some experienced validators? Here goes.

I'm aware of https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa (and
pictures at street level), but it would be really helpful to have some
actual satellite images with the typology overlaid as well. E.g.

   - an image of a section with "highway=tertiary". Comment: You can see
   the paved road surface, it's a wide road - definitely tertiary. Most likely
   these should all be marked already.
   - an image of a section with "highway=tertiary". Comment: You can see
   it's unpaved, but it's quite wide (two vehicles can pass), and connects
   several major settlements - still use tertiary
   - an image of a section with "highway=unclassified". Comment: You can
   see it's unpaved, and looks quite narrow (two vehicles cannot pass easily),
   but it's usable by 4x4. Use unclassified.
   - an image of a section with "highway=unclassified". Comment: You can
   see it's unpaved, and looks quite narrow, but it's usable by 4x4. Although
   it only goes to one settlement, use unclassified.
   - an image of a section with "highway=residential". Comment: Short roads
   between buildings.

Other comments that would be useful (if they can be made):

   - If you are not sure what to use: Use unclassfied over residential (or
   other way round).
   - Use path over track (etc).
   - (http://www.openstreetmap.org/user/Johnwhelan's suggestion) If you can
   see a road going to a house with metal roof, that road is most likely
   passable by vehicle: use unclassified, rather than track/path.

MapCSS:

   - highway=residential and unclassified look the same in JOSM. Would be
   good to have an adjusted MapCSS (Africa.css) that distinguishes those, and
   (ultimately) gives more prominence to the features we are interested in.

Final suggestion: Wiki page
https://wiki.openstreetmap.org/wiki/Building_Tag_Africa. I saw a
presentation somewhere (Ralph?) with images of buildings (round huts,
square houses). It would be good to set up a new wiki page with those, to
help in mapping buildings.

As I said above, I'm very happy to help with all of these. E.g. if some of
the validators would be happy to pass images to me (maybe as they are
validating and re-tagging or extending road networks), which I would be
very happy to collate, post to the wiki, and write text. Or start putting a
MapCSS together and check it into git, etc...

Any takers?
Bjoern

Re: [HOT] Buildings and residential areas: Buldings as nodes (Q1)

2017-05-20 Thread Vao Matua 
My opinion is that buildings should be mapped as areas.
In un-mapped areas it would be best to create landuse=residential areas
first rather than quickly tagging buildings with single nodes. When it
comes time to trace buildings it is troublesome to convert single nodes to
polygons.
For existing single node areas they could be cleaned up on an as-needed
basis.

Dear both, dear all,

If we're agreed that it's better to map buildings as areas - should we try
to re-map node-buildings from previous campaigns as areas? Or shall we just
leave it?

Many thanks,

[HOT] Validate this task if you consider that the work is complete.

2017-05-20 Thread Daniel Specht 
Using the task manager for validation, a speech bubble comes up saying
"Validate
this task if you consider that the work is complete."  The bubble blocks my
view of the comment I'm writing. If there are many previous contributors,I
can just scroll the comment box down, but this doesn't work  for the first
few contributors. Would it be possible to hide the bubble when the user
mouses over it?
