This February, 2000 set of 20 slides contains 14 global views of the Earth in full color shaded relief, showing land and undersea topography. The planet is seen from vantage points over the poles and each major ocean and land mass. Also included are a rectangular Mercator projection view of the whole Earth, as well as displays of crustal plates and their relation to world seismic activity. The images are computer-generated from a digital database of oceanic bathymetry and land topography.
These slides replace a previous version issued in 1991 from lower-resolution, less complete data. The new slides were produced from original images of 3300x2200 pixels, so resolution is excellent. The original data points were spaced every 2 minutes of latitude and longitude; the images represent a reduced resolution of about 5 minutes while preserving all important physiographic features.
