The Space Oblique Mercator projection, the Conformal Space Projection (CSP) (Cheng 1996) and other space map projections
have all been designed specifically for satellite imagery that is scanned around a nadir ground track, such as SPOT and Landsat imagery.
We consider some conformal map projections
in the common form as presented by Snyder (1987) as our reference basis.
1) are held fixed, whereas all necessary reductions due to map projection
will be considered.
Arno Peters, a German historian and cartographer, developed his map projection
in the 1970s.
A successful Geographic Information System (GIS) relies on the proper selection of map projections
and the skill of the primary user(s) in managing and converting projections.

AJ Klinghoffer takes us on an intriguing 1,000-year worldwide journey to illustrate the problem, in the process emphasising the fact that the well-established map projections
of Mercator and Peters can be badly misleading, albeit in very different ways (Mercator's 1569 map has accurate shapes, but exaggerates the Arctic and diminishes tropical lands, Peters' 1972 map is equal-area, but has distorted shapes).
The CCCM site uses the MapGuide Dynamic Authoring Toolkit (DAT) to generate some additional advanced features such as dynamic map projections
to convert the current map view into the local coordinate system familiar to the users as well allowing the map to only show layers that are pertinent to the region currently in view.
Absolute location such as using grids (latitude and longitude), different types of maps and globes (thematic maps show population, economic systems, climate zones, political divisions, and settlement patterns), map projections
(to change from a spherical earth to a two dimensional map sheet), as well as earth-sun relations (to determine climate, seasons, and time zones).
