Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. It's 100% free, no registration required.

Is there a website out there that will let me markers (lat/lon) and bounding boxes (minimum / maximum lat/lon) and let me see it overlayed on top of Google Maps (or OSM, or Bing, etc)? I'm not really looking to create my own webpage for this... I'm hoping someone's implemented something like this for a general use case or a demo and it's online somewhere.

Google Maps Example:

You can run this example from you local drive.

enter image description here

You could simply add a form to enter the coords rather than the code.

for changing the extents set the new google.maps.Rectangle({ bounds:new google.maps.LatLngBounds(new google.maps.LatLng(37.2, -122.3), new google.maps.LatLng(37.6, -121.9)), to the values you want.

new google.maps.Rectangle({
    bounds:new google.maps.LatLngBounds(new google.maps.LatLng(37.2, -122.3), new google.maps.LatLng(37.6, -121.9)),
    map:map,
    fillOpacity: 0.2,
    strokeOpacity: 0.5,
    strokeWeight: 1
  });

Open Street Map Example:

For Open Street Map you can just call the API to generate a simple rectangle by adding &box=yes to the call

enter image description here

This has markers, but I don't see a way to add a bounding box. –  Pris Jul 13 '12 at 19:47
    
Gotcha, the easiest way then would be just to take the bottom sample from Mapperz solution and change the bounding box. –  dkroy Jul 13 '12 at 19:51
