Hi!
The instantaneous location of a vehicle can be identified with the help of a GPS module and it can be read from a PC using a GPS receiver and Arduino. The location coordinates can be read continuously by manipulating the arduino code. Now, in most of the tracking projects I browsed in the internet, if the location has to be plotted on a map, just one location coordinate is sent to google maps and that location is indicated on the map.
But, what I am interested in is, I want to display the location of a moving vehicle continuously on a map thus displaying the path traversed by the vehicle. Now, there are projects that store the path of the vehicle in a SD card or as a file and then the data is sent to google maps thus displaying a track. But I want the path of the MOVING vehicle to be transmitted and plotted instantly (live locations).
These are the requirements of my project:
The vehicle is travelling in an area for which a map is available offline. There is no cellular network in the area. There is no internet and hence the popular "Google Maps" cannot be used.
The location coordinates are transmitted by some wireless communication module and the receiver gets the data and sends it to the arduino.
I want to mark the path travelled by the vehicle in the available map continuously while the vehicle is in motion.
NOTE: The vehicle is in an open area that is around 500m wide.
What is the solution for this? How can I mark the path of the moving vehicle in an offline map?
srnet:
You could describe where this 'area' actually is ?
If its only 500M wide then there are a number of radios that will cover that distance in the open.
Hi!
The area is a remote testing facility to test unmanned vehicles and there are no cellular networks/tower in the area! Is there any way that I could track the live location of the moving vehicle and mark its path in an offline map?
And if you have any idea how to continuously mark the live path of the vehicle on google maps, I'm glad to hear about it! As all the projects I have come across plot the single location (as sent by the GPS module) on the map.
Thanks!
The vehicle is travelling in an area for which a map is available offline. There is no cellular network in the area. There is no internet and hence the popular "Google Maps" cannot be used.
Google Maps can be downloaded and used off-line. An alternative is OSM.

get an offline map - download an appropriate section of Google Maps, OSM, or whatever you like (not an Arduino thing).
get your vehicles to send their coordinates on a regular basis to the base station (I guess you want this real time - otherwise store it on SD card).
plot the received coordinates on the map using some graphics software (not an Arduino thing).
Are there any digital aerial photographs available for the area? In the USA digital aerial photos are used in photogrammetry to produce planimetric maps and contour maps of land areas. If your area has these aerial photos available you could use them (probably just one for a 500m square) to plot the location of the vehicle. A digital ortho in the form of a TIF file will have with it a TWF file which contains information on the scale and coordinates of the pixels in the file. If you can get the GPS coordinates (latitude & longitude) of the vehicle you may be able to convert them to the coordinate system used in the photograph to plot the location of the vehicle. I don't think this is something to attempt on an Arduino.
