OpenStreetMap
hi-res imagery for Leyte and problems with OSM :(
Posted by backpacking philippines on 28 June 2012 in English.i visited bato, leyte a few weeks ago and there was still no hi-res imagery for this area when I checked and OSM has just the major roads
now there’s satt image and a mapper beat me to it. I don’t agree with the road tags with most set to secondary and tertiary though. most of them are residential with just the main highway as primary plus the road to the port of bato
also noticed another mapper is changing the road tags for Surigao del Sur changed main roads of some towns from secondary to residential. entire towns were enclosed with land use tagged as residential areas oblivious of the fact that there are commercial areas on major roads :(
the problem with Open Source :(

You could try sending a polite message to those other mappers pointing out why you think what they have done is not fully correct. That would be better than just adjusting tags, as otherwise they will continue in the same way.

There’s a big probability that the mapper(s) who uploaded the roads are just armchair mappers. If you check their history and see edits all over the world, or a lot of edits far away from where you live, you can just change the tags to the values you like. You live there, so you have the right to do so.
They probably think initial data is better than no data, and that’s true.
I also added some streets in Nigeria (after a call here), I’m sure some tags are wrong, but at least the tracing is done, changing tags is easier than tracing.
If it’s not an armchair mapper, try to contact him/her and come to a resolution. Point to documentation here: http://wiki.openstreetmap.org/wiki/Philippines or create new documentation when there isn’t enough.
For changing values, you should certainly contact the mapper.

(If this is a double post, sorry, but the first reply didn’t seem to come through)

If you click on the Bing Aerial (Labeled) layer in this link: http://tools.openstreetmap.org.ph/imagery_coverage/#10.3271,124.791324,17
The closed source data is even worst. Unfortunately, I cannot edit it. The problem with closed/proprietary. :)
Perhaps we can also discuss this in the PH mailinglist so that other mappers can help and standardize the tags.

thanks for all replies…have yet to act on this one
maning, BONG missed Ormoc, of all cities there :( have an upcoming trip to Palompon and explore calanggaman island
the good and bad of open/closed source
perhaps we can issue standards/guidelines on street tagging plus the reasons why. it’s more of map zooming and routing priority for me :P
