  persons or a group of groups can have a one or
  more types of rights or SocioalTenureRelations
  associated, where each right concerns one or more
  SpatialUnits SpatialUnits can overlap and can
  always be identified with a label.
• A right or SocialTenureRelation is always in
  between Persons and SpatialUnits.
• There can be different registrations/recordation's
  in Land Administration for one territory

Kisumu evaluation

• Enumeration different type of registration and
  documentation
• Accepted by the community
• Data sets are convertible to STDM
• Co-ordinate systems allow for combination of
  data-sources also historical
• Maintenance of data low quality cadastral map
• Maintenance of data enumeration data
• Need for GNNS Infrastructure
• Need for co-operation
• Policies may require different data acquisition
  methods
