Somehow people dont take it seriously when i tell them some concepts or idea. They think I am just talk and wont walk the talk. I dont know till to date why people do that or may be there is something in my appearance that make them think i am more dumb they can even imagine? Now thats a big joke if they assumed things based on my appearance or external body language :D
Let me roll back 3 yrs, I was running around showing people that I know an easier way to get this online map/routing for indian cities. Some said "Its nothing new", some said "we have already done it and we flopped", some went ahead to give me hope before they pulled the ground underneath me. Since no one listens or no one thinks its do-able...here is the way.
Atleast in india, the govt has to be ashamed that its doing nothing in terms of providing GPS data or data regarding locations. The geological society of india has sided with private entities in making this public domain data...a privileged one. But somehow they have given/shared the data to private parties, but on the contrary in the US...everything atleast some part of the data is in the public domain. So getting data in india is virtually impossible within a time frame unless one gets those data personally. Creating data of the location, streets, landmarks etc is easy and its just that everyone thinks its manual labor and dont have a clue how to do that.
Here is my way.....
* each city can be broken down into different areas and localities.
* Each of such layouts have a sort of a blue print plan of the place.
* You have Autocad like softwares to plot and retrieve the coordinate values of the place.
* There are GPS devices which can be used to get the lat/long values of any landmark or places.
* Then use triangulation method to map any point retrieved from the GPS system onto any map.
* Then make it commercially sensible by charging businesses that wants to be displayed onto the map.
* Going in for service regarding fleet tracking, call center cab's tracking etc, logistics, shipment tracking etc.
The dynamics/math behind position or location mapping can be seen here

I used shape function method to retrieve any location entrapped within 3 given points

Concept behind fleet tracking
From the GPS data, one can figure out the street co-ordinates. Say for example
* Street AB connects point A and point B.
* A street is a line connecting A(x,y) and B(x,y)
* Any point on this line can be found out by the straight line equation.
* An allowance or tolerance can be set like say + or - 1m accuracy to tell if the vehicle is on that street.
* Now perpendicular distance between a point and a line is given by
d=|(Ax1+By1+C)/(sqrt(A^2+B^2))|
where A, B, and C are the coefficients of the general equation of a line Ax + By + C = 0 and (x,,y,) are the coordinates of the point.
* Now if d is within 1m accuracy then you are sure that the vehicle is on the street.
