Formulas for the Web Mercator are fundamentally the same as for the standard spherical Mercator, but before applying zoom, the "world coordinates" are adjusted such that the upper left corner is (0, 0) and the lower right corner is ( , ): [7] = ⌊ (+) ⌋ = ⌊ ( [ (+)]) ⌋ where is the longitude in radians and is geodetic latitude in radians.
Google Maps, which relied on it since 2005, still uses it for local-area maps but dropped the projection from desktop platforms in 2017 for maps that are zoomed out of local areas. Many other online mapping services still exclusively use the Web Mercator.
Vincenty relied on formulation of this method given by Rainsford, 1955. Legendre showed that an ellipsoidal geodesic can be exactly mapped to a great circle on the auxiliary sphere by mapping the geographic latitude to reduced latitude and setting the azimuth of the great circle equal to that of the geodesic.
Find the coordinates (generally latitude and longitude) of the geographic location you want to link; Select the template with the appropriate scale for the map to zoom into; Add the coordinates to the template using the template's format; Place the template reference into the article; Suggestions for accomplishing each step are below.
Center the screen on your location by double-clicking on it, then use the View in Google Maps button at the top (Google Earth 4.1 and newer). This will open Google Maps within Google Earth. You can see the center coordinates in decimal format in the address bar, but unfortunately you cannot copy them directly.
The projection coordinates resulting from the various developments of the ellipsoidal transverse Mercator are Cartesian coordinates such that the central meridian corresponds to the x axis and the equator corresponds to the y axis. Both x and y are defined for all values of λ and ϕ. The projection does not define a grid: the grid is an ...
The table is indexed by latitude at 5-degree intervals; intermediate values are calculated using interpolation. Robinson did not specify any particular interpolation method, but it is reported that others used either Aitken interpolation (with polynomials of unknown degrees) or cubic splines while analyzing area deformation on the Robinson ...
Without a reliable source, the larger the object being mapped, the less precise the coordinates need to be. Cities must be specified with a precision of degrees, minutes and seconds to respect historical norms. When the #Which coordinates to use guideline is used, degrees, minutes and seconds or d.dddd are the default. To specify a particular ...
