Map projections and coordinate systems 2 sets of gis nr 143 conic projection is a slightly more complex form of conic projection because it intersects the. List of map projections conic in standard presentation, conic (or conical) projections map meridians as straight lines, and parallels as arcs of circles. On an equidistant map, distances are true only along particular lines such as those radiating from a single point selected as the center of the projection. Unit 27 - map projections ie, in a conic projection all distances from the center are represented at the same scale c figure of the earth.

Equal-area projections, especially the albers equal-area conic, and equidistant projections which have correct scale along many lines appear in the national atlas. Conic projections a family of projections based on a cone being placed over the world and the earth locations projected on it it is cut from the base to the apex and unrolled to form a map cylindrical projections a family of projections based on placing the world in a cylinder (without ends) and projecting the earth locations onto it.
Conics the following was conic projections are not widely used in mapping because of their relatively small zone of reasonable accuracy the secant case. Map projections and coordinate systems it is similar to the albers conic equal area projection except that the lambert conformal conic projection portrays.
