GIS Image coordinates / markers?


#1

Hey everyone,
Is there Rails support for something like Google Maps, but using my
own images/maps?

Basically, I’d like to have my own maps/images, be able to drop
markers on them, center on certain attributes etc.

google maps is just javascript so you can drop it in anywhere on your
rails views.

As for custom images i believe this is set in the google API
javascript as follows:

var icon = new GIcon();
icon.image =
http://labs.google.com/ridefinder/images/mm_20_red.png”;
icon.shadow =
http://labs.google.com/ridefinder/images/mm_20_shadow.png”;
icon.iconSize = new GSize(12, 20);
icon.shadowSize = new GSize(22, 20);
icon.iconAnchor = new GPoint(6, 20);
icon.infoWindowAnchor = new GPoint(5, 1);

Thanks, but what I was looking for was something with the interface of
Google Maps, but my own maps, like maps of buildings, or more
detailed areas.

There is code that does exactly that in "Pragmatic Ajax’ (1).
Even better, what you’re looking for is freely available :
