Thanks a lot for all the replies.
Yes, the GPS maps i was talking about is Google Maps. What i wanted to
know is that, is it possible for me to develop something like
GoogleMaps application, by getting raw data in shapefile format and
compiling it? I came across a software that says it can convert raw
shapefile data to Maps (www.everlymap.com) . Let me give a brief of
what i intend to do. I work for a software company and we intend to
enter into the GPS space. But before anything we need to understand
something about GPS, how it works etc. So we started off with
developing a simple Passive GPS tracking application where the user
travels with a handheld GPS (a GPS device with inbuilt memory), and at
the end of the trip, we can connect the GPS to the PC and get the
route the person travelled. To plot the route travelled, we need maps.
Initially we looked at Google Maps, which comes with API and this can
be easily done using Google Maps. But the thing is Google Maps are not
free to use in Enterprise Applications. So i started looking at some
alternative. Thats when i came across 'Navteq' and asked them about
the maps, and they said ''We only provide raw map data. For example,
Google is our customer and they use their software to compile our data
as what you see in Google Map. How they do it, I got no idea. Without
any software compilation, the map is just raw data format.' So i was a
little confused, which made me ask the above question. I hope i have
made my ideas clear.
