equivalent projection Explanation: Mivel a földfelszín nem sík, a térbeli alakzatok síkra vetítésekor elengedhetetlenül torzulnak egyes paraméterek. A térképészetben számos eltérő vetületet alkalmaznak, attól függően, hogy mely jellemzőket kívánják torzításmentesen megőrizni. A vetület angolul projection, és itt szerintem az equivalent/equidistant/conformal projection az angol megfelelő. "A map projection is any method of representing the surface of a sphere or other shape on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion. Depending on the purpose of the map, some distortions are acceptable and others are not; therefore different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties." http://en.wikipedia.org/wiki/Map_projection "Map projections Because the earth is round and maps are flat, getting information from a curved surface to a flat one involves a mathematical formula called a map projection, or simply a projection. This process of flattening the earth will cause distortions in one or more of the following spatial properties: Distance Area Shape Direction No projection can preserve all these properties; as a result, all flat maps are distorted to some degree. Fortunately, you can choose from many different map projections. Each is distinguished by its suitability for representing a particular portion and amount of the earth's surface and by its ability to preserve distance, area, shape, or direction. Some map projections minimize distortion in one property at the expense of another, while others strive to balance the overall distortion. As a mapmaker, you can decide which properties are most important and choose a projection that suits your needs." http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicNam... "equal-area (also called equivalent, equiareal or authalic) projection" http://www.progonos.com/furuti/MapProj/Dither/CartProp/AreaP... "Classification of map projections Map projections can be described in terms of their: - class (cylindrical, conical or azimuthal), - point of secancy (tangent or secant), - aspect (normal, transverse or oblique), and - distortion property (equivalent, equidistant or conformal)." http://www.kartografie.nl/geometrics/Map projections/body.ht... |
