Grab is messing up OpenStreetMap data in Southeast Asia

I guess it depends on the sat image source which leads to costs.

I'm sure you can use the newest/best data for your company because you can pass on the costs to your clients.

We indeed pass the cost of imagery to customers, but it's flexible. I.e. given the location and customer requirements we have a decision tree that picks the best image source from multiple providers based on freshness, spatial resolution, cost, and some other factors.

How does that tree approximately look? Which providers are there?

In the "high spatial resolution" - i.e. 50 cm per pixel or less the well-known providers everyone is using are Digital Globe, Airbus or Nearmap. Above 50 cm it starts to get hard to confidently see enough detail.

Google maps terms of service actually prohibits using satellite imagery for feature extraction ( https://cloud.google.com/maps-platform/terms/ ).

Bing is the best on the cheap end. Actually, Bing donated imagery for OSM mapping purposes ( https://wiki.openstreetmap.org/wiki/Bing_Maps#Bing_Aerial_Im... ).
