Transverse Mercator (Very Common)
Name | Transverse Mercator (very common) |
Model | Cylindrical |
Type | Conformal |
Meridians | Complex curves concave toward a straight central meridian Straight central meridian intersects equator and one meridian at 90 angle |
Parallels | Complex curves concave towards the nearest pole |
Spacing Meridian | Spaced at their true distances on the straight central meridian Spacing increases away from the tangent meridian |
Spacing Parallels | Spacing increases away from the tangent meridian |
Linear Scale | True along line of tangency OR Two lines equidistant from and parallel to the line of tangency |
Specialties | Shape is true only within any small area Enlargement of area increases away from the tangent meridian Reasonably accurate within 15 band along line of tangency Cannot be edge-matched in an east-west direction if each sheet has its own central meridian |
Uses | UTM Zones Widespread usage by many countries throughout the world Area of interest has a predominantly North-South extent |
