Re: [talk-ph] intro to Kaart initiative in PH

[Erwin Olario]

Glen, thank you for sharing.

Road surface types, and lanes, is one of the attributes we hope to collect
and add into the the OSM database. The challenge of "how" to collect these,
is another matter altogether. We have limited street-level imagery (and
that's one way of doing that), and in many urban areas, users can use
aerial imagery to distinguish paved and unpaved roads.

Re: [talk-ph] Mayon Volcano Eruption Jan 2018

The objective of the area I created was to include evacuation centers I
mapped before that were used by APDRRMO in 2014 [0] for the phreatic
eruption event plus covering the pyroclastic flow and lahar flow hazard
area released by PHIVOLCS [1]. Might be a good idea in the future to map it
for navigation to the evac centers and escape routes too.

Ervin,

Thanks, this is so much bigger than the EDZ [0].  I feel its too much
too big AOI for mapping.
If we can have detailed poly that identifies at risk areas, that's much better.

I can't find my poly to geojson coverter right now, can you share
geojson or shapefile?

Thanks everyone for finishing the task really quick!  We have 100%
mapped and 57% validated as of this time.
Also thanks to the mappers before us who already mapped a lot before this event.

We created a new task to include the expanded danger zone [0],
reference material [1].
Compared to the previous task, this needs more effort since these
areas are more populated than the permanent danger zone.

This continues to be a local response, but anyone is welcome to participate

Re: [talk-ph] intro to Kaart initiative in PH

[Glen Scott]

Nothing to offer by my own personal experiences

I'm a regular user of GPS for navigation at home (Australia) in urban and
country environments.  I've noted in OSM (Philippines - specifically N-W
Pangasinan) two things that are undefined in 99% of roads, but used by the
routing engine - road surface and speed limit. With 99% of roads undefined
for surface and speed limit the route chosen by the GPS will be a lottery
as far as driving experience goes.  I guess the most critical would be the
ability to chose to avoid unpaved roads?  I've had a number of Garmin GPSs
and they always assume 80 km/h where the map has no defined limit.  Maybe
10+ years ago I had some experiences where the GPS would attempt to take me
on "short-cuts" over long-unused dirt tracks (in preference to the
highway!).  I guess this is the potential result of not defining the
surface at the very least.  Hard to tell the speed limit from satellite
imagery!

In the urban environment the most common and frustrating errors (Garmin
maps) would be undefined one-way streets.

My one attempt to navigate in the Philippines on OSM (~2008-2009) led me
into a military camp and some interested military personnel who directed me
back out the way I came in!  Gates are important but no always so easy to
see from space

Cheers
Glen
