This morning through the Google Lat Long Blog I learned about the Henry Hudson 400 Foundation’s Google Map. This map has some great resources for history teachers and students. Through the map you can view routes of Hudson’s voyages. What could really make the Henry Hudson 400 Foundation’s map a good educational resource is the map collection of historical map overlays and stories about the first settlements in Manhattan.

The Google Earth Blog has a short write-up about the 3D models layer utilized in the map.
