This is a map of the actual hight, most of this area is below see-level and a sort of drained wetland.

And the dike of "Amsterdan Rijnkanaal" belong to "dijkring 14", braking this dike will put a great part of holland underwater.

The map itself was a challenge, how to implement the nature of this area.
Most of this is grassland, water or urban area.
Water or urban area was not a problem.
But grassland from this area can be a challenge.

This almost of water.

This give me 3 types of grassland.
normal type, very small [green/blue] canal around the hex, Mobility Hindrange 5.
challenging type, small [blue] canal around the hex, Mobility Hindrange 7.
imposable type, medium [blue] canal around the hex, Mobility Hindrange 9.
The background of the hex-tiles below see level have a different [more blue] structure, Elevation 1. the rest Elevation 2 but the background of elevation 1, for a creation of a level 0.
This map is made of a original version around 1990.
