Subject [jira] Created: (SIS-8) Build a common SIS data container for spatial data
Date Wed, 18 Aug 2010 14:10:15 GMT
Build a common SIS data container for spatial data

                 Key: SIS-8
             Project: Spatial Information Systems
          Issue Type: New Feature
            Reporter: Chris A. Mattmann
            Assignee: Chris A. Mattmann
             Fix For: 0.2-incubating

The QuadTreeNode has the concept of a data container per node in the QTree, but I'd like to
extend this to a general SIS spatial data type. This would in part be motivated by e.g., [1],
where the suggestion is something like:

Any measurement we take in Earth and environmental sciences, although this is often ignored,
has a spatio-temporal reference. A spatio-temporal reference is determined by (at least) four

1. geographic location (longitude and latitude or projected X,Y coordinates);
2. height above the ground surface (elevation);
3. time of measurement (year, month, day, hour, minute etc.);
4. spatio-temporal support (size of the blocks of material associated with measurements; time
interval of measurement);
