I created an export in OpenStreetMap for an address in Melbourne, Australia with a zoom level of 14: http://www.openstreetmap.org/export#map=14/-37.8593/145.0390. The export coordinates changed depending on whether I view it in Firefox, Chrome or Microsoft edge. Why does this variation happen?

I assumed that the export would be the same given the same coordinates and the same map size/zoom level (i.e. 14). Is there a way to achieve that?

  • Chrome:

    export in chrome

  • FireFox

    export in firefox

  • Edge

    osm export in microsoft edge

    Is it because your browser windows are a different size? If I resize my Firefox browser, the coordinates change - they have to, because the exported area fills the browser window... – Spacedman Oct 14 '17 at 15:49
  • you could also try full-screen mode in the browser, usually f11 to toggle (works in FF and Chrome, not sure about Edge). – Steven Kay Oct 14 '17 at 16:31

After hitting the "Export" button, the download URL to actually fetch the .osm file is like this:


so It looks like you could construct that with the specific bounding box coordinates you want. The view on the web page is influenced by the size of your browser window, which might be why you see different bounds in different browsers.
