Hi guys, Ed recently pointed to OSRM (Kaybiang Tunnel thread) and I noticed that the OSRM map includes MapBox satellite imagery as a selectable background layer. I checked it out and found out that there are plenty of places where there is high-resolution satellite imagery for at least zoom level 14, including places where there is no Bing satellite imagery. Most places are in B&W.
Some places with high-resolution imagery in MapBox but not in Bing: - Pag-asa Island, Palawan (colored, pixellated though) - eastern Catarman - western Siquijor - Dipolog - eastern Surigao City - central northwestern Bohol - southern Negros Oriental - eastern Kalibo - downtown Calapan (very cloudy though) - Baler, Aurora - practically all of Batanes (colored!) - central-western Marinduque (colored) (not including Boac) - Cagbalete Island, Quezon (colored) - 90% of Patnanungan, Quezon (colored) - Science City of Muñoz and San Jose, Nueva Ecija (colored) - Atimonan, Quezon (colored) - western Guimaras The question is, is this available for tracing in OSM? Based on the latest info from MapBox, they intend that their satellite imagery is traceable (but only) for OSM: http://support.mapbox.com/discussions/general-questions/16348-satellite-openstreetmap-tile-servers-and-other-goodies In fact, you can select "MapBox Satellite" as one of the default background layers in JOSM as well as the new OSM editor, iD. However, this default layer shows nothing in the Philippines (and most of the world outside US) except Landsat imagery (low zoom layers only) in both iD and JOSM. But when I grabbed the tile mapping service (TMS) URL used by OSRM, I get access to the high-resolution tiles: JOSM: http://{switch:a,b,c}. tiles.mapbox.com/v3/dennisl.map-inp5al1s/{zoom}/{x}/{y}.png iD: http://a.tiles.mapbox.com/v3/dennisl.map-inp5al1s/{z}/{x}/{y}.png Potlatch 2: http://${a|b|c}. tiles.mapbox.com/v3/dennisl.map-inp5al1s/$z/$x/$y.png Go ahead and try these URLs. BUT PLEASE DO NOT TRACE YET!!! I am mystified by why there seems to be two types of MapBox satellite imagery layers. One, that is available by default in iD and JOSM but shows nothing, and another that has plenty of high-resolution imagery available. I am guessing there are licensing issues that exists. I will ask the MapBox people first. Hopefully they can provide a proper TMS URL that we can use. :-) Eugene
