Re: [talk-ph] Grab in conflict with Thailand OSM community
Hello All, Just wanted to quickly clarify on our usage of images. We do not stick with any one default imagery to map a city. We do a random check to find the best suitable imagery basis ground truth alignment and strava heat maps and use it as default imagery. However we do refer to all available images to cross check our edits accuracy before uploading them live to osm. We might end up making some edits which might be in line with ground reality, and that's where we seek guidance and feedback from local team.

Re: [talk-ph] Grab in conflict with Thailand OSM community
Is it a concern that they keep referring to Bing imagery "We will also use Bing imagery to ensure there are no missing roads". In the parts I've looked at, some roads on Bing just don't exist any more! Bing is good for coastline where there has been no human development, but not good for anything else. Using Bing imagery to check for roads will create the classic GPS nav problem - OLD DATA = WRONG WAY!

Re: [talk-ph] Grab in conflict with Thailand OSM community
Hi JP, Grab/Global Logic's mapping team have reached out to the OSMPH community to inform and coordinate with us their mapping efforts for the Metro Manila[1][2], San Fernando[3], Binalonan[4] and Metro Cebu[5] areas. They have also participated in the OSMPH and OSM Asia Telegram group chats to ask quick questions. Based on spot checking of their work in the Philippines, it seems that they are doing a good enough job with the mapping of the road network.
