Want to download the map to help you explore?

Here are two Google Maps that you can download for your personal use. (You will need to zoom in a lot to see the detail).

The map titled RSL shows canal as single lines, that titled RPL shows them as polygons that can be clicked to show more detail. Clicking the square brackets at the top right corner of the map will open it in your ‘Google My Maps’. See the ‘Explanatory Notes’ page for more detail.
