Kauai Relief Maps

Here are improved versions of relief maps for Kauai and Niihau. See thing:106099 for the earlier version. There is also a high resolution map of a portion of the north coast of Kauai.

The three maps are:

Kauai_step.stl 140 x 190 points at 12 arc second intervals
Niihau_step.stl 200 x 200 points at 6 arc second intervals
Kauai_coast.stl 175 x 175 points at 1 arc second intervals

Data for the first two maps came from NOAA

Data for the high resolution map was from the USGS National Map.
