  4. Albers projection - Wikipedia

    en.wikipedia.org/wiki/Albers_projection

    Snyder [6] describes generating formulae for the projection, as well as the projection's characteristics. Coordinates from a spherical datum can be transformed into Albers equal-area conic projection coordinates with the following formulas, where is the radius, is the longitude, the reference longitude, the latitude, the reference latitude and and the standard parallels:

    The Robinson projection is neither equal-area nor conformal, abandoning both for a compromise.The creator felt that this produced a better overall view than could be achieved by adhering to either.

  8. Map algebra - Wikipedia

    en.wikipedia.org/wiki/Map_algebra

    Map algebra is an algebra for manipulating geographic data, primarily fields.Developed by Dr. Dana Tomlin and others in the late 1970s, it is a set of primitive operations in a geographic information system (GIS) which allows one or more raster layers ("maps") of similar dimensions to produce a new raster layer (map) using mathematical or other operations such as addition, subtraction etc.
