OpenStreetMap
In India, MapMyIndia is one of the biggest aggregators of commercial map data, including running their own fleet of mapping cars, so it was quite interesting to find OSM data in their map for areas i’m familiar with and have mapped on the ground.
Its not all OSM though, will need to dig more into how they mix the data.

“Dig more” - for what exact purpose?

To find where OSM ends and propriety data begins, or if everything is just mixed.

That’s pretty much obvious. But what’s the final goal - just to know that?

How could I access the MapMyIndia map? From their main website it didn’t seem obvious. Is it paywalled? I’d be interested in checking some of the areas I mapped, to see how they compare.

@keithonearth, they have modern fancy navigation that only looks good but is quite counter-intuitive. Here is a direct link to MapMyIndia map.

Try MMI. From comparing the Himalayan village I fieldmapped Rakkar, I think the OSM data in MMI dates back to sometime in 2013. The changes I made in 2014 are not there.

Wouldn’t have been this a case for https://wiki.openstreetmap.org/wiki/Lacking_proper_attribution ?
