In a desktop Qt application, I have some GPS coordinates that I'd like to show on a map. My plan is to construct an URL with the coordinates and let a web browser and Google maps or a similar service do the heavy lifting.

After reading some apparently reverse-engineered documentation at

mapki.com slash wiki slash Google_Map_Parameters

I can make it work for a single point, but what's the URL syntax for multiple points?

My best shot so far is to build a string such as this:

http://maps.google.com/?ie=UTF8&[email protected],17.82&[email protected],17.82

but that will only show "My Second Point". Is there a better description of the syntax somewhere?


Replacing q= with markers= did not work and the "static map" suggestion below only complained about an incorrect API key.

A: 

for google maps static there is this URL:

http://maps.google.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=14&size=512x512&maptype=roadmap
&markers=color:blue|label:S|40.702147,-74.015794&markers=color:green|label:G|40.711614,-74.012318
&markers=color:red|color:red|label:C|40.718217,-73.998284&sensor=false&key=MAPS_API_KEY

i am not sure if this syntax is also good for standard maps

Throwing parameters at maps.google.com only gets you one point.

As dusoft says, you could use Google Static maps.

Or, if you require dynamic maps, you could write your own public web page that uses Google Maps API and accepts a long list of parameters. Use your own web page in exactly the same way that you were intending to use maps.google.com web page, except that you get to design what you want the parameters to look like.

Perhaps something like this.
