What is a cylindrical projection?
A cylindrical projection can be imagined in its simplest form as a cylinder that has been wrapped around a globe at the equator. If the graticule of latitude and longitude are projected onto the cylinder and the cylinder unwrapped, then a grid-like pattern of straight lines of latitude and longitude would result.
The meridians of longitude would be equally spaced and the parallels of latitude would remain parallel but may not appear equally spaced anymore.
In reality cylindrical map projections are not so simply constructed. The three aspects of the cylindrical projections: Tangent or secant to equator is termed regular, or normal.
Tangent or secant to a meridian is the transverse aspect.
Tangent or secant to another point on the globe is called oblique. Originally prepared for the Seminar in Map Projections and is currently being adjusted to a common format with the other Map Projection Pages. Come from two sources: Anderson, these are graphics containing the graticule shorelines and 2.
Shaded maps by Peter H. Dana, The Geographers Craft Project. Regular cylindrical projections Lines of latitude and longitude are parallel intersecting at 90 degrees.
Scale along the equator or standard parallels is true. Can have the properites of equidistance, conformality or equal area. Equirectangular Projection Among the oldest projections and simplest. Parallels are equally spaced.Cylindrical projection, in cartography, any of numerous map projections of the terrestrial sphere on the surface of a cylinder that is then unrolled as a plane.
Originally, this and other map projections were achieved by a systematic method of drawing the Earth’s meridians and latitudes on the flat surface.
The map projection is the image of the globe projected onto the cylindrical surface, which is then unwrapped into a flat surface. When the cylinder aligns with the polar axis, parallels appear as horizontal lines and meridians as vertical lines.
A map projection is one of many methods used to represent the 3-dimensional surface of the earth or other round body on a 2-dimensional plane in cartography (mapmaking). This process is typically, but not necessarily, a mathematical procedure (some methods are graphically based).
If a surface can be. A map projection in which the surface features of a globe are depicted as if projected onto a cylinder, typically positioned with the globe centered horizontally inside the cylinder. Distortion of shape and scale in a cylindrical projection of the earth is minimal in equatorial regions and maximal.
A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane.
Maps cannot be created without map projections. All map projections necessarily distort the surface in some fashion. Depending on the purpose of the map, some distortions are. cylindrical projection [sə-lĭn ′ drĭ-kəl] A map projection in which the surface features of a globe are depicted as if projected onto a cylinder typically positioned with .
