hi i am final year student doing project on gps
pls can u tell me how can i do the program to mapping the latitude and longitude of data received from gps with database (place) by using freescale S12X micro controller ..now i get the data from gps as nmea formate how can i change it to normal data.pls if anybody knows help me..
thank u..
 

I never done yet. I'm sure, this is needed you to have database with coordinate number and the place name.
If the microcontroller not enough memory to save, you need to save in external memory chip or save in SD Card.

Normal operation to get the location name, is use compare gps reading with the database. But, I don't know how fast to compare if there are many location in database.

1. you need to maintain a database for the parameters you wish you process. ( lat and longitude)
2. You get straight forward data from GPS. you dont have to do anything to read it in proper format. you only have to write a routine to read the required parameters like GPGGA etc.
The information you get itself have the information of lat and longitude.
3. first gather the data and compare it with your database and print the location name.

thank u..
is there any method for comparing gps data with database (which is stored in micro controller memory)
and also do u know how to store and access the data in mc9s12xdt512 micro controller...
pls if u know means help me..
thank u..

it is better to use eeprom or external memory for your project.
you have to read the string coming in the GPS input.and break the incoming data into seperate longitude and latitude values. and do a string compare of the values received and the data stored in the database memory.
If the data is matched then map it to corresponding place which is again stored in database.
