Automatic Dataset Compositing
Fully automated run-time compositing of multiple datasets, correctly positioned based on pixel resolution and latitude/longitude at a corner.
Any number of datasets may be composited (although performance is degraded slightly with each one added).
Allows user to do such things as view high-resolution insets of particular celestial objects or regions of the sky overlaid on top of lower resolution imagery of the whole sky.
Example below shows screen captures of four composited datasets (IRAS, Hipparcos synthetic map, 2MASS, and DPOSS).
