Purpose of test: Look at individual maplets in detail, and to see what we procedures we could use that are not usually implemented.
Main thing we've learned is that because of overlaps, if there is no maplet with a center near the top of the boulder then the height of the boulder may not get represented very well. With the 35cm global shape model large boulders were not being represented because overlaps between maplets were not lining up, hence the boulder was not represented. We learned the SPC doesn't represent steep slopes very well, so it would "break" at a boulder. We think perhaps the large slopes were simply resented as 0 slope. See the presentation where I show a single maplet on it's side. On top of the boulder small variations were represented, the edge of the boulder was not represented at all, and then the surrounding topography again had the small variations represented. So the result is a relatively flat map that represents small topography.
Bigmap doesn't have that limitation. If there are two maplets of different widths and different radius vectors, a near 90deg slope will appear at the boundary between the two maplets. See Presentation link below for an example.
