In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to … See more Many properties can be measured on the Earth's surface independently of its geography: • Area • Shape • Direction See more One way to classify map projections is based on the type of surface onto which the globe is projected. In this scheme, the projection process is described as placing a hypothetical … See more Conformal Conformal, or orthomorphic, map projections preserve angles locally, implying that they … See more • Geodetic datum • Geographic information system (GIS) • Geoinformatics See more The creation of a map projection involves two steps: 1. Selection of a model for the shape of the Earth or planetary body (usually choosing between a sphere or ellipsoid). Because the Earth's actual shape is irregular, information is lost … See more The three developable surfaces (plane, cylinder, cone) provide useful models for understanding, describing, and developing map projections. … See more The mathematics of projection do not permit any particular map projection to be best for everything. Something will always be distorted. Thus, many projections exist to serve the many uses of maps and their vast range of scales. Modern national … See more WebThis course is the basic introduction of GIS. It gives an insight of the GIS system especially the projection systems. ... Let's have a look at properties of map projections and in particular distance and direction. Let's start with a fairly straightforward map projection.
