Nautical Overlay

This website from GeoGarage layers nautical maps geo-rectified to fit Google’s brand of Mercator. The slider control allows you to adjust the transparency. First you must acknowledge that you can’t trust these maps for actual navigation! They are designed for planning and analyzing. Nice little routing tool allows you to plot a course including distances, and export to a Garmin GPS devise. Seems like huge potential here.

On the subject of trees, here’s another reason to love Amsterdam. A green city, it is. This interactive map is in development, along with others like this one showing green roofs. The inspiring collection is here.
