Building a GPS navigation System... |
|
|
For my College thesis i must build a gps navigation system but im
pretty lost right now and i cant find any solid information...
i have CAD maps of my city/state bu i have no idea to what format i
have to convert them to in order to be usable by a GPS nav system... i
know it has something to do with DBases but not much more to go on
other than that...
after i make the actual map i must start on the buildin of the
visualizer of the map [gps app itself] gps will be fed by usb port...
two problems arise... how do i referenciate the gps coords with the map
and how do i trace routes on it... i need to build the nave system to
be able to delete streets and avenues temporarily during a query since
im building it for emergency services.... and sometimes streets here
get bloked and/or flooded... the program will problably if i get help
will include a graph node structure to find the best route posible and
find alternate routes...
can anyone help me... im really short on time as in less than a month
short... i havent been able to fin info and no one here knows the
technology other than seing it on tv or using a premade one....
plz help me im desperate..... |

Why not just buy one... creating a gps navigation system is
not original research (unless you are doing something really
new).
GPS receivers can output positional data in geodetic coordinates
via NMEA sentences, which, in turn, can be imported into a computer.
You could write software to overlay the data on your maps.
You might want to research how maps are geo referenced.

They are usually proprietory to each individual GPS system. And for most
companies they are closely guarded secrets.

The GPS coordinates give you the lat and long, which you should know what
they are for your maps, so you just plot the position on the map. Basi

Isnt' that the point of your project?

tbh I can't see why you are doing this. For a thesis it needs to be novel
work, I can't see any orginality in this. |

So you have to read the GPS data from the serial port and display a map
which you already have. That comes down to basic mathematics and programming
work. If you cannot do that, I wonder how you will ever be able to pass this
test.

Then I guess you are in deep sh*t....

There are topographical systems which can use imported maps. However they
can't usually do 'navigation' |
