Martin Desruisseaux commented on SIS-9:
---------------------------------------
This work is partially done in SIS 0.6 but not yet finished. We have the
capability to read a spatial reference systems from WKT but not yet from EPSG
codes. We also have some map projection implementations but only the simplest
ones. We have the capability to do some coordinate conversions but not yet
datum shifts.
> Allow for multiple spatial reference systems

> 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.
