Working Amongst Map Projections
Projection Face is a smashing example of the distortions created past times unlike map projections. The interactive shows how 64 unlike map projections trial our stance of the globe past times showing each projection's trial when applied to something really familiar, the human face.
The distortions of each of the unlike projections cab hold out illustrated farther past times clicking too dragging whatsoever of the mapped faces. This illustrates how the unlike map projections tin hold out distorted themselves only past times changing the oculus of the map.
Projections Face is an interactive version of a 1924 example from Elements of Map Projection amongst Applications to Map too Chart Construction.
Degenerate State's Map Projections tool is unopen to other interesting visualization of how unlike map projections distort our flick of the world. Map Projections is a really like tool to Projection Face but this interactive shows you lot how map projections genuinely trial maps.
The tool allows you lot to stance a map of the globe using xi unlike map projections. This inwards itself is a skillful demonstration of the choices cartographers brand when depicting a iii dimensional sphere on a 2 dimensional plane. However Map Projections also allows you lot to explore how these unlike map projections would alter if you lot changed the 0,0 indicate of latitude too longitude on the map.
If you lot click anywhere inwards the globe therefore the map volition automatically alter to present the distortion needed if this was the root of the map.
If you lot desire a picayune aid deciding which map projection you lot should role for your electrical current map projection therefore you lot tin role the Projection Wizard to hit upward one's hear on the best projection.
This map projection direct allows you lot to select the extent of the map stance you lot are working amongst past times outlining the expanse on a Leaflet map. Once you've highlighted your map bounds you lot tin select a distortion belongings (Equal-area, Conformal, Equidistant or Compromise).
The Projection Wizard volition therefore propose which map projection you lot should role depending on the extent too the distortion belongings of the map. The suggested projections are based on 'A Guide to Selecting Map Projections' past times the Cartography too Geovisualization Group at Oregon State University.
Influenza A virus subtype H5N1 Proj.4 link is provided adjacent to each suggested projection, which opens a popup window amongst a Proj.4 library. Once you've settled on your map projection you lot mightiness desire to check-out the Proj4Leaflet plugin for using projections supported past times Proj4js amongst Leaflet powered maps.
