street even - you encounter a few shops - say a big Sweet and Snacks / Hotel / School / anything, on the same street. Now how do you put those on the maps while GPS tracking and then tracing the map on the computer?
paper and pen
I mean, the to reach the shop, you have to walk good 5meters or such - at times - depending on width of foot path or such. Now those paths are not roads really, and they can vary from place to place. How to tackle such offsets ?
measure it
2) Suppose you have tracked certain part of your town oryour route from your home to airport near your city. Then you fly to another city and then restart the GPS device. At that point the device generally has to re-initiate itself to capture/detect the satellites ( which it has to do anyway incase you turn off and then switch on a gps device - atleast in some devices that I have seen ). Anyway after it has done that, it calculates the Longitude and Latitude and hence the current position. What happens in this case is, the GPS device draws a straight line from City A to City B. Is there a way to avoid that / tackle that ?
no way to avoid it - delete the line
