The internet search giant is planning to bring out 3-D maps of Indian cities soon. According to Androidos report, Delhi will be the first city to get a 3-D mapping from Google. Google had launched a free-turn-by-turn -voice navigation last year.
It is also seen that Google Maps on Android phones already show a few colonies of Delhi in 3-D. The work is in its beta stages and for now only a few colonies in the city have 3-D mapping. The project originally was announced in 2010 December, as part of Google Maps 5.0. As per Google listings, more than 100 cities globally have the 3-D buildings support.
The technique used by Google to create 3-D maps is vector graphics. With the help of vector graphics, the map can be drawn dynamically in the device even while using it. This also allows user interaction like rotating and tilting 3-D maps.
The original date of launch of 3-D maps is not known at the moment. Since already a few colonies in Delhi have started appearing in 3-D, it may not be too far for the launch. The users will be able to spot other cities and colonies in India pretty soon in 3-D.
Google had announced the 3-D map facility to users of iPad, iPad-2 and iPhone4s. This included cities like Rome, Francisco, San Diego, Santa Cruz, Los Angeles and Boston. Google had also promised its users that it will keep expanding its 3-D map feature to all new locations as soon as possible.
