We have just extended coverage of our ITO Map overlay map service to most of the USA and Canada and all the Caribbean islands (ie all of the USA except Hawaii and Alaska and all of Canada except the northern wilderness). Read more on the ITO Map wiki page and in the earlier announcement accompanying the release for the UK and parts of Europe.
Users of the existing European service may notice that we have reduced the maximum zoom level for 8 to 10 for some scripts and increased it from 11 to 10 for some others. Further expansion of the service will come by the end of next week.
This first screenshot highlights lakes, rivers and ferry routes in British Columbia (lakes in light blue, rivers in dark blue, coastline in green, canals using tan and ferries in read). Click on any of these screenshots to open the browser for the given views. Keys are provided for all overlays in the bottom left corner of the map. Clicking on the key takes one to further details on the OSM wiki.
This next view is of railways in New York (Mainline services are in black, underground rail in red and light rail in blue).
This next one is for speed limits in Seattle (lowest speeds are green, higher speeds in purple and blue). Full details in the key.
And finally electricity distribution around Baltimore with sub stations in red, power distribution in various colours according to voltage and black where no voltage is specified.
