  34. Summary • Point Data: use points or multi-points. • Grids: Use a lat/lon bounding box if appropriate, otherwise use a spherical n-gon. Accuracy is more important than speed. • Tiled Data: A form of regional grid, use a lookup table. • Scenes: Use a spherical quadrilateral, maybe up to a spherical decagon for larger scenes. Speed is more important than accuracy. • Orbits: The best way to define the coverage of an orbit is to define the orbit. The best way to search for orbital data is to search orbits. Use Backtrack.
