Jan 1, 1993 · Mapmakers and mathematicians have devised almost limitless ways to project the image of the globe onto paper. Scientists at the U. S. Geological Survey have designed projections for their specific needs—such as the Space Oblique Mercator, which allows mapping from satellites with little or no distortion.

Mar 1, 2023 · The USGS uses the Universal Transverse Mercator map projection for their topo maps. This projection reduces distortion for regions with a small east-west extent, while distortion increases as one moves away from the central meridian.
USGS: Map Projections. descriptions and comparisons of several map projections. What is a Planetary Image Map? A primary capability of ISIS3 is to create map projected images of raw instrument data. This allows researchers to make fundamental measurements on and observations about the images.
May 21, 2023 · Within the realm of maps and mapping, there are three surfaces used for map projections (i.e., surfaces on which we project the shadows of the graticule). These surfaces are the plane, the cylinder, and the cone.
