Nearly a year ago I posted my gripe regarding the inaccuracy of Google Maps road data for Manila, voicing out my concern and hoping Google will do something about the situation.
Last night, Google announced the answer to my prayers: earlier Google formally launched Google Map Maker here in the Philippines, allowing ordinary users to populate map data which will later be pushed into Google Maps.
While the service has yet to be reflected in Google Maps, the map data has so far been promising, and is a far cry from the map data that is currently available in Google Maps:

The data in these maps are not yet perfect: there are roads which have inaccurate names, and a lot of location data for banks, gas stations, schools and the like are not yet there. Also, while Metro Manila street data is fairly extensive, there are still some gaping holes and missing roads in several areas. Rural road data likewise tends to be more sparse.
If you have intimate knowledge of provincial roads and city streets as well as establishments outside of NCR, or even just of the streets and establishments around your neighborhood, Google Map Maker needs you to make the maps more accurate, informative, and consequently, useful. You would only need to have a Google account to sign in.
