This contains the shapefiles for the structures mapped in the SBMT. 

- 00_all: contains a file for each type of feature mapped, containing all features.

- Regions_50k: contains the shapefiles to load the region and subregion definitions
  with 50k facet resolution to the SBMT

- <region_name>: for each region there is a folder with at least a file containting
  all paths in the region (niches, terraces, scarps, rims, pits and fractures) 
  and a file containing all ellipses in the region (boulders, craters, mounds 
  and bright patches). If some of the features mapped correspond to other autors
  different files are created with the extension _own or _<author_name>. The authors
  correspond to Giacomini, Auger and Vincent in the following papers:

  - Giacomini: Geologic mapping of the Comet 67P/Churyumov–Gerasimenko’s
               Northern hemisphere.
  - Auger:     Geomorphology of the Imhotep region on comet
               67P/Churyumov-Gerasimenko from OSIRIS observations
  - Vincent:   Large heterogeneities in comet 67P as revealed by
               active pits from sinkhole collapse
