[talk-ph] Grab in conflict with Thailand OSM community

[grab osm]

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.

Thanks Lavanya
