Goode homolosine is an equal-area (equivalent) projection. But there are significant disadvantages too; obviously there is the problem of the oceans (and Greenland) being split apart . Its principal disadvantage is that distances are greatly distorted Greenland appears larger than South America when its actually one-ninth the size. It projects the entire Earth into a circle, though the polar regions are subject to extreme distortion. Goode homolosine projection SW.jpg. mapserver. This means that when we attempt to flatten our round planet to the two-dimensional plane of websites and journal articles, we make certain assumptions based on the intent we've set for our map. Goode homolosine is an equal-area (equivalent) projection. 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. What is wrong with the Mollweide projection? It was developed by J. Paul Goode in 1923 as a merging of the Mollweide (or Homolographic) and Sinusoidal Projections, thus giving rise to the name . This has made using specific projections quite simple, as one can refer to them by their EPSG code. It is most commonly used in interrupted form.

The Hammer-Aitoff projection is another attempt to improve shapes on an equal-area projection. Goodes HomolosineHelp | ArcGIS Desktop - Esri Other Meridians: Equally spaced sinusoidal curves between the 4044'11.8'' parallels and elliptical arcs elsewhere, all concave toward the central meridian. The ocean-oriented version uses -140, -10, and 130 meridians in the northern The poles are presented with two, three, or four points, depending on If you think this file should be featured on Wikimedia Commons as well, feel free to nominate it. The result is a slight, visible bend in the meridians at 4044'11.8'' N and S. The higher latitudes are the top sections of a Mollweide projection, grafted to the sinusoidal midsection where the scale of the two projections matches. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles. (Most of the time.). This grafting results in a kink in the meridians along the parallel of the graft. However, when I try to create a CoordinateReferenceSystem object with this projection, GeoTools complains it has no transformation. Date 15 August 2011 Source Own work Author Strebe Licensing[edit] Its equal-area property makes it useful for presenting spatial distribution of phenomena.

If you have a machine that can read the whole 600M+ binary file in without choking then great. Directory of Map Projections Goode homolosine The traverse aspect of an elliptical projection puts the pole in the center of the map instead of the equator. Its equal-area property makes it useful for presenting spatial distribution of phenomena. The distortion values are symmetric across the equator and the central meridian only in the uninterrupted form. What does it mean when the map projection distorts the earth? Map projections are interesting, complicated, and mostly handled for us. 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. The homolosine evolved from Goodes 1916 experiments in interrupting the Mollweide projection.[1].

This means that when we attempt to flatten our round planet to the two-dimensional plane of websites and journal articles, we make certain assumptions based on the intent weve set for our map. 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). Interrupted forms can be used for focus maps on land or ocean as originally presented by the inventor. As I am working on a continental scale (South America) I need to reproject to WGS84.

Imagery is a derivative of NASA's Blue Marble summer month composite with oceans lightened to enhance legibility and contrast. This projection is fully supported by both PROJ and GDAL. Allan Lee Collection of Map Stamps: Volume 6. The Mollweide is another example of an elliptical map. It is. Frequently plotted with some northern regions repeated on different interrupted sections to reduce . The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for global maps of the world or night sky.
