* New section on Positioning classes. ISO 19123 provides a means to
specify affine coordinate conversions and general coordinate
transformations, but not non-affine coordinate conversions. Most Map
projections fall into this category. Proposed an addition which plugs this
hole.
I will try to look at the new section as soon as I can (I have too many thing to do in the same
time...). I'm not sure what the ISO 19123 coordinate conversions is for. But OGC 01-004 had a "grid
to CRS" transform, which is really an affine transform in the vast majority of cases. Reprojection
were handled by the "Resample" operation, which is an other story.
I will try to give a more pertinent feedback after I will have looked at yours document. Thanks for
writting that up,
Martin.
