WEBIf the developable surface touches the globe at only one point or line, this is called a tangent projection. If it touches at two, this is called a secant projection. Figure 5.4.3 illustrates the difference between a tangent …

WEBIf the cone touches the Earth at just one particular parallel of latitude, it is called tangent. If made smaller, the cone will intersect the Earth twice, in which case it is called secant. Conic projections often achieve less …

WEBIn some projections, the projection surface touches in one location, called a Tangent or line of tangency. Projections can also intersect or cut ‘behind’ the globe’s surface creating two locations or lines where the …

WEBFor tangent cylindrical and conic projections or secant planar projections (resulting in one standard line), place the standard line in the middle of the map extent. When using cylindrical and conic secant projections, place …
