Subject [jira] Created: (SIS-9) Allow for multiple spatial reference systems
Date Wed, 18 Aug 2010 14:14:15 GMT
Allow for multiple spatial reference systems
--------------------------------------------

                 Key: SIS-9
                 URL: https://issues.apache.org/jira/browse/SIS-9
             Project: Spatial Information Systems
          Issue Type: New Feature
          Components: distance functions, geometry objects, web services layer
            Reporter: Chris A. Mattmann
             Fix For: 0.2-incubating


We should really support the ability to move between multiple spatial reference systems. Right
now, we are implicitly assuming WGS84, but there are plenty of others, e.g., North American
Datum of 1983 for one. As part of this, we should support conversion between different geoids,
the ability to parse and read existing files and determine their reference system (maybe this
should be an issue in itself), and conversion functions to take SIS data and go back and forth.
Of course, this has large implications on distance functions, existing geometric operators
and spatial comparators.
