Projects the globe onto an octahedron with symmetrical components and contiguous landmasses that may be displayed in various arrangements. 1975 Cahill–Keyes projection

In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. [1][2][3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. [4][5] Projection is...

Explore the Earth with the 3D interactive globe. Latest high-resolution 3D satellite imagery. The globe is a three-dimensional model of the Earth.

2022年11月29日 · We're long overdue for an accurate world map. Get the real story behind different map projections and see which one is the most accurate map of the world.

2024年12月26日 · Following is a list of the map projections that may be viewed and saved by G.Projector as of version 3.4.1, along with alternative names and also some parameter-specific and other special cases. Sample images of an Earth topographical map are linked for each unique projection. Conformal. See Quartic Authalic. Conformal. Azimuthal, minimum-error.

G.Projector transforms an input map image into any of about 200 global and regional map projections. Longitude-latitude gridlines and continental outlines may be drawn on the map, and the resulting image may be saved to disk in GIF, JPEG, PNG, TIFF, PDF, PS or SVG form.

The best way to represent the Earth is with a globe. But map projections can be awfully useful too. Find out why cartographers use map projections in GIS.

2024年9月17日 · Students use oranges to investigate the effects of changing a 3-D surface to a 2-D surface. They then examine the distortions of different map projections while comparing land and ocean to its representation on a globe.

2019年8月31日 · In no particular order we give you our top 10 world map projections. 1. Mercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. Its ability to represent lines of constant course from coast to coast made it …
