r9534 r9535 26 26 * <p> 27 27 * There are two forms of the oblique mercator, differing in the origin of their grid coordinates. 28 * The {@linkplain HotineObliqueMercator Hotine Oblique Mercator} (EPSG code 9812) has grid 29 * coordinates start at the intersection of the central line and the equator of the aposphere. 30 * The {@linkplain ObliqueMercator Oblique Mercator} (EPSG code 9815) is the same, except the 31 * grid coordinates begin at the central point (where the latitude of center and central line 32 * intersect). ESRI separates these two case by appending {@code "Natural_Origin"} (for the 33 * {@code "Hotine_Oblique_Mercator"}) and {@code "Center"} (for the {@code "Oblique_Mercator"}) 34 * to the projection names. 28 * The Hotine Oblique Mercator (EPSG code 9812) has grid coordinates start at the intersection of 29 * the central line and the equator of the aposphere. 30 * The Oblique Mercator (EPSG code 9815) is the same, except the grid coordinates begin at the 31 * central point (where the latitude of center and central line intersect).
