GPS and Google API in Processing

jgmourag

How can I read gps coordinates and show this in a map ? I have a map using the GoogleMapper library. Does anyone has an example or something ????

Depends where you want to get them. Device? Text file? Internet API?

Perhaps search (from the main site) the GPX keyword...

Hi Philho, I will use an GPS MODULE( FOR ARDUINO). My idea is to get the coordinates with gps module and transfer the coordinates for an Google API and show in the map.

Hi, for example send from arduino to processing:

            float lat = 49.1234567;
            float lon =2.123456789;
            void setup() { 
            Serial.begin(9600);
            }
            void loop() {
              Serial.print(lat,6); //,number of decimal
              Serial.print(",");
              Serial.println(lon,6); 
            delay (5000);
            }

for receiving data in the processing googlemapper, it is similar to:

void setup(){
....
   myPort.bufferUntil('\n');  
}
void draw()...


void serialEvent(Serial port) { 
    String fromArduino = port.readStringUntil('\n');
    if (fromArduino != null) {
     float[] arduCoords = float(split(fromArduino, ","));
     println( arduCoords[0]);
    println( arduCoords[1]);

    lat =arduCoords[0];
    lon =arduCoords[1];
    mapCenterLat=lat;
    mapCenterLon=lon;
     }
    }
