... IMHO you should notI'm not complaining, just thinking about what would be possible if ImageJ
supported all the data models and world coordinate systems of just the
FITS standard (generalized hyperstacks, highly non-linear coordinates,
all known map-projections).
say that a certain model is very primitive unless you have come up with a
I'd be happy to ablidge. These things were taken care of (literally) ages ago in astronomy - being a small, global community, we needed good standards early on:
- generalized hyperstacks (1981)
- generalized tables (1995)
- generalized coordinates (2002)
- every known map-projection (2002)
Of course, this is just a data-representation made for storage (that's what the FITS standard is all about), but the appropriate properties of a generalized data model are well illustrated by the constraints placed on being able to store such data. The FITS header mechanism is primitive but easy to use and makes the bookkeeping associated with generalized hyperstacks/tables/coordinates/world-coordinate-systems fairly manageable (and is much more powerful than that used in TIFF or JPEG).
Since most of you are interested in plain imaging (even if it is n-dimensional), it was natural that ImageJ only supported the simplest data forms, but once you get to know and love (!) ImageJ, you want to be able to do other things as well.
It is great idea, but we should perhaps estimate to what degree current users
would benefit from alternative coordinate systems and projections at this
stage of the ijx development. I guess that it would not be a trivial task (but
perhaps I am very wrong).
This could attract a large number of new users and contributors from the
Astronomy/Geography sciences. Is that a priority at this particular point?
If it is, it might be worth considered finding a group of additional
contributors -rather than the current team- to contribute on implementing
these additional features, so the ijx development is not sidetracked from its
It might be a matter of contacting the right people, perhaps through Frederic,
who brought up this issue?
