I thought this was an FAQ, but couldn't find any answer from someone
at Google. The Wikipedia page on Google Map Maker states:
"The project is similar to OpenStreetMap, but unlike OSM
which provides its map data under a Creative Commons
license, any maps created by users of Google Map Maker
are the intellectual property of Google."
OpenStreetMaps is free, more open, already in place, has extensive
coverage, and lots of mechanisms to improve maps: software that parse
GPS tracks and uploads the data to OSM, browser-based map editor, and
even an Android GPS navigation app that maps unknown places as you
drive through them (AndNav2). OSM lets us in the USA, UK, Australia
and other "well-mapped commercially" countries update the map with
punctual local knowledge which the big commercial guys don't bother
with (new or temporarily closed roads, location of post boxes etc.).
Wikimapia is also completely open, CC-licensed, and has identified of
some of the most obscure buildings you'd want.
Therefore, I have a few questions:
In the context of OSM, what is the purpose of Google Map Maker?
How is Map Maker / Map Your World better than Open Street Maps?
Can't GMM simply slurp all the data from OSM, then build off that?
How will the GMM data be available? For example, 3rd navigation
software is not allowed to use Google Maps for turn-by-turn direction
(that's why AndNav2 exists - AndNav1 uses Google Maps, but could not
give directions turn-by-turn).
I'm not saying GMM is a bad idea (I personally prefer the openness of
OSM); competition will hopefully improve both products. It would be
interesting to contrast the two system and find out the rationale for
creating GMM and reasons why I'd use it over OSM.
