what is the goode homolosine projection used for

Normally it is presented with multiple interruptions. They each define a different version of the Earths geometry, and thats all well say about that here (its easy to get into a rabbit hole with datums/geographic reference systems, so well avoid that). Goode homolosine is an equal-area (equivalent) projection. the same. File:Goode homolosine projection SW.jpg - Wikimedia Commons It is a combination of Mollweide (or homolographic) and sinusoidal projections, hence the name homolosine. There is no distortion along the central meridians and the equator. For an ellipsoid, the semimajor axis is used for the radius. The homolosine evolved from Goodes 1916 experiments in interrupting the Mollweide projection.[1]. The PROJ string is rather simple: +proj=igh +lat_0=0 +lon_0=0 +datum=WGS84 +units=m +no_defs The IOGP (. 2023 QNA Experts - All Rights Reserved The equal-area property and some other distortion properties are not maintained when an ellipsoid is used. Goode homolosine is an equal-area (equivalent) projection. Flattened Orange (e.g. Goode's homolosine projection is a combination of the Mollweide and sinusoidal projections. See Projection Units for more information. The author assortedly removed ocean segments to focus on land masses. The Goode homolosine projection (or interrupted Goode's homolosine projection) is a pseudo- cylindrical, equal-area, composite map projection used for world maps. Radius of the sphere, given in meters. Up to latitudes 404411.8N/S, the map is projected according to the sinusoidal projections transformation. It is available in ArcGIS Pro 1.0 and later and in ArcGIS Desktop 9.2 and later. Two Thousand Years Those spherical coordinates I mention above are referencing a location on a sphere (or, in the case of Earth, an elipse), and as such they have to be in reference to some definition of that sphere. Despite the slight improvement in shapes, the curved latitude lines make the map harder to construct and use. The sinusoidal projection is used between those two latitude values for the equatorial part of the world. Because the Mollweide is sometimes called the "homolographic projection" (meaning, equal-area map), Goode fused the two names "homolographic" and "sinusoidal" (from the sinusoidal projection) to create the name "homolosine". Distortion. This page is not available in other languages. AuthaGraph AuthaGraph.

Advantages: It was made famous when the National Geographic Society adopted it as their reference map of the world from 1922 until 1988. a two-cm square anywhere on our paper map has the same surface area on the globe), or perhaps preserving the real shapes of landmasses is important. Scale is true along every latitude between 4044' N and S and along the central meridian within the same latitude range. In the uninterrupted form, bulging meridians produce considerable shape distortion toward the edge of the projection.
