I am making a program that uses GPS location preferably from smart phone, laptop works too and compares it to a building, the points you in its general direction. I am making this web application specifically for San Jose State Campus for fun. I have read the other posts about the correlation between decimal places and accuracy and a .11m error will be sufficient. Google maps gives me coordinates to the 6th decimal place, I was wondering if they do indeed follow the standard I have read about here. Here is an example of one of the buildings I will index.
I will only have an arrow point in the direction of the building and rotate it as the lat/long of the user changes and maybe display the approximate distance from the building. I have yet to learn how to properly use google api to draw the users path and etc and that is why I am asking.
