A nautical chart is a geographical map which provides relevant information, such as depths, and the location of channels and buoys.

Latitudes and longitudes, coast lines, shallows along coasts and rivers, sand banks, buoys, beacons and other shallows are indicated on these – nowadays – yellow-coloured nautical charts using numbers. The depths and shallows, especially along the coast, are indicated using defined, curved contours, per depth, just like a weather map with bars indicating high and low pressure. These depths are usually stated in lengths, but also in metres.

The map sheets are not available online. Use the form below to request (parts of) the digital map files from the TU Delft Library Map Room.
