Rapa Iti Island - Marplot Map with 50-m Contour Intervals (1:60,000)
Finally, I'm going to put this project to rest. My first post about this island happened back in July 2006. I was new to mapping contours and did not attempt it with this project. In March 2007 I commented on voids that occur within SRTM data. The voids contain no data and consequently, no contours are generated for these area. The above Marplot map contains 50-meter contour intervals for the entire island. The SRTM data I used (SRTM_08_18.asc) comes from CGAIR. It is reworked SRTM data with voids filled, whenever possible.

The above two images show how accurate these contours are. I wouldn't want to build a house based on them, but I would hike around and over the island using them.

This final map shows the fine harbor and anchorage on this island. The community is called Ha'urei. It is home to the 126-voice Tahitian Choir. There is an NRP segment that plays some of the music and talks with the musicologist about his recordings. Wikipedia has alittle information about the island as well. My original post of July 2006 has a good deal of information about this island.
