The pi and GPS

Tue Mar 15, 2016 5:49 pm

Hi

I was wondering if i attach a GPS Module to the Pi and open a browser would i be able to navigate that way?

ie open google maps and say go here would it know where i'm currently located?

I'm not locked in to any browser so i can go with anything

well it only clearly told how to get the gps data in to the pi


not how i would open maps.google.com and enter a TO address and have it figure what route to take based on where I'm currently

I guess you just need to install and configure GPSD ,
enable "Share my location" in Iceweasel (which is a renamed
Firefox) and Google Maps should do the rest automagically ...

Perhaps you need to modify some settings too , like
shown here :

how can I use GPS locations on a map on my screen retrieved by a GPS sensor and Google maps or OpenStreetMaps if I have no internet access (i.e., offline) ?
#define S sqrt(t+2*i*i)<2
#define F(a,b) for(a=0;a<b;++a)
float x,y,r,i,s,j,t,n;int main(){F(y,64){F(x,99){r=i=t=0;s=x/33-2;j=y/32-1;F(n,50&S){t=r*r-i*i;i=2*r*i+j;r=t+s;}if(S){PointOut(x,y);}}}for(;;);}

download a map and store on the SD, just like navigations systems for cars are doing it.
If not Google maps, then OSM if applicable.
Finally on my mobile robot I have no WiFi outdoors!
#define S sqrt(t+2*i*i)<2
#define F(a,b) for(a=0;a<b;++a)
float x,y,r,i,s,j,t,n;int main(){F(y,64){F(x,99){r=i=t=0;s=x/33-2;j=y/32-1;F(n,50&S){t=r*r-i*i;i=2*r*i+j;r=t+s;}if(S){PointOut(x,y);}}}for(;;);}

ehh? why should i download a map?

It was you who asked what to do when there was no internet access, for myself i will just use my 4G dongle with 30gb data a month and use Google Maps

??
download a map because then it's offline available, even without having internet!
and then I can use my GPS sensor, poll latitude and longitude, load the offline map on my screen, and display a "X" where my robot currently is located.

just on a car navigation system, there you also have no internet connection!
#define S sqrt(t+2*i*i)<2
#define F(a,b) for(a=0;a<b;++a)
float x,y,r,i,s,j,t,n;int main(){F(y,64){F(x,99){r=i=t=0;s=x/33-2;j=y/32-1;F(n,50&S){t=r*r-i*i;i=2*r*i+j;r=t+s;}if(S){PointOut(x,y);}}}for(;;);}

What about using Navit, it's in the pi repositories
apt-cache search navit
It's an open source car navigation system that can use OSM data.
http://wiki.openstreetmap.org/wiki/Navit
I've never tried it but it might be worth a go.

no I don't want a route finder, I need the location displayed on a map even when the robot is off-road on an acre and no Wifi on the acre.

I actually did not interprete the TO question "google maps and show GPS position" so closely, but then please devide the topic in 2 as there already have been questions and answered postings!

Sorry, I was replying to the original post not to yours. But having said that, if Navit works the same as other satnavs it will display your current location on a map. You don't need to use the navigation part of it and as it uses downloaded maps you don't need the internet or wifi.

aaah! that's indeed promising!
I'll try to figure out how it works with my GPS (it's plugged to an Arduino extension board like a shield, data transmitted to th Pi via i2c) and then I will give it a try!
Thank you very much!

Why I was thinking of google maps is that I can link to that

What i'm actually doing is making a micro car pc for the local pizza delivery's car

A ras pi with the 7"inch screen is plenty enough for them, and they have no shortage on mobile broadband either.

what they do is calling a webage that shows all orders for delivery, each order has its own link that opens the order and address along with a link that CURRENTLY opens googles own navi app on android, and also a link that works on iphones

So my thought was simply mod the link to open google maps on a new tab
