equal-area map projection homolosine projection- an equal-area projection map of the globe; oceans are distorted in order to minimize the distortion of the continents map projection- a projection of the globe onto a flat map using a grid of lines of latitude and longitude ...
Equivalence (the equal-area property of a map projection) is important to some categories of maps. However, unlike for conformal projections, completely general techniques have not been developed for creating new, computationally reasonable equal-area projections. The literature describes many specific ...
内容提示: ALBERS EQUAL-AREA CONIC MAP PROJECTION >, Paul D. Bame / ^ Hewlett-Packard ' Colorado Springs, Colorado \ / Map projections are used to show a portion of a sphere or ellipsoid, usually earth, in two dimensions in some reasonable way—they usually try to reduce a specific type...
a cartographer who has since retired from the US National Park Service, began looking at equal-area projections to identify an alternative to Gall-Peters. When he didn’t find any good options, he contacted Bernhard Jenny and Bojan Šavricˇ to find if they would be interested in developing...

圆柱等积 (Cylindrical equal area) 投影 说明 圆柱等积投影可将世界呈现为一个矩形,同时保持地图上的相对面积。 瑞士数学家 Johann H.Lambert 于 1772 年首次描述了这种投影。自那以后许多年,出现了多种变体。该投影适合绘制赤道附近地区的大比例地图,且一般不建议用于绘制小比例(世界)地图。它适用于ArcGIS Pro...
The Lambert azimuthal equal-area projection maintains land features at their true relative sizes while simultaneously maintaining a true sense of direction from the center.
这种投影是一种适用于绘制世界地图的等积圆柱投影。 投影方法 圆柱投影 - 标准纬线位于 30° N 和 30° S(圆柱等积的一种情况)。 接触线 位于30° N 和 30° S 的两条纬线。 线性经纬网 经线和纬线都是线性的。 属性 形状 标准纬线附近区域的形状变形最小。在标准纬线之间,形状将沿南北方向变形,在 30...
1772 年兰勃特最先描述了这种等积投影。但这种投影很少被使用。 投影方法 在与赤道相切的圆柱上进行等轴透视投影。 交点数 赤道。 线性经纬网 在竖直方向或赤道投影上,所有的经线和纬线都是直线,且相互垂直。各条经线的间距相等,且其长度是赤道长度的 0.32 倍。各条纬线的间距不相等,且距赤道最近的纬线间距最大...
