FYI. This rendering is very useful for rural areas and perhaps to monitor DPWH road projects. ;) ---------- Forwarded message ---------- From: "Jean-Guilhem Cailton" <j...@arkemie.com> Date: Dec 20, 2011 11:12 PM Subject: [HOT] "OpenUnpavedStreetMap", "South continents", Colombia, soon Philippines To: "HOT" <h...@openstreetmap.org>
Hi, Knowing whether a road is paved or not is an important information for a driver, especially in countries where many roads are unpaved. This information can be entered in the OSM database with the surface tag [1], but it is not currently rendered in the main maps available on osm.org [2]. Seeing it rendered on a map would likely be an incentive for mappers to use it, especially beginners. A map with a rendering for this, OpenUnpavedStreetMap, is now available for Africa, Central and South America, Australia-Oceania (according to Geofabrik's definition, which includes Indonesia and Malaysia), and soon several Asian countries, including the Philippines (actually the countries available as extracts from GeoFabrik, China, India, Pakistan, Vietnam, etc.except Japan - considering dataset size). Surfaces tagged as "compacted", "gravel", "sand", "dirt", "earth", "ground", "grass", "mud"... are also considered as "unpaved", following the wiki page. Examples from areas that may be of interest on this list: - Port-au-Prince, Haiti: http://osm.arkemie.org/haiti/?zoom=17&lat=18.60871&lon=-72.28598&layers=B0 - Kigali, Rwanda: http://osm.arkemie.org/ousm/?zoom=16&lat=-1.95416&lon=30.08243&layers=B000F - one of the examples given by Douglas, in Kampala, Uganda: http://osm.arkemie.org/ousm/?lat=0.38093&lon=32.55812&zoom=18&layers=00B0T - A page for Colombia, with markers for the GeoRSS feed from la Sala de Situación Humanitaria Colombia: http://osm.arkemie.org/ousm/colombia/ Following Humberto's suggestion, flood_prone areas are also rendered ("flood_prone=yes" or "flood_prone=label"): http://osm.arkemie.org/ousm/colombia/?zoom=16&lat=10.39717&lon=-75.15048&layers=B000FT Following a suggestion from Federico, and a need that had also appeared for Haiti, next step should be rendering of POIs relevant for emergencies, such as health facilities, at lower zoom levels. The global URL is: http://osm.arkemie.org/ousm/ OSM.org Mapnik layer is in the menu for easy comparison on the current area. A "hybrid map for mappers" - and for soon-to-be mappers who can see what might be missing on the map ;) - is available by overlaying a transparent version of OpenUnpavedStreetMap with Bing aerial imagery. Google satellite imagery is also available as a reminder, by comparing imageries location, that it is often advised to adjust Bing offset before tracing. The database is updated at least daily, and minutely for the next days, after the new coverage will have been imported. Tiles are available from http://osm.arkemie.org/ousm_tiles/${z}/${x}/${y}.png http://osm.arkemie.org/ousm_transparent_tiles/${z}/${x}/${y}.png The current bandwidth is limited, but if you are interested, let me know. Let me know what you think, and if there are features that would be interesting for a custom rendering.
