MATLAB学习与使用：8种地图投影方式

1、圆柱投影（Cylindrical）。在命令行窗口输入maps后回车，可以查看MATLAB提供得8大种地图投影方式，共计71小种方案。下面挑一些方案展示其投影效果。运行下面脚本，依次看到balthsrt,behrmann,lambcyln,mercator四种方案的圆柱投影。close all,clear all,clcload coast %加载海岸线%圆柱形投影，有balthsrt,behrmann,lambcyln,mercator等方案subplot(2,2,1);axesm balthsrt;patchm(lat,long,'g')subplot(2,2,2);axesm behrmann;patchm(lat,long,'g')subplot(2,2,3);axesm lambcyln;patchm(lat,long,'g')subplot(2,2,4);axesm mercator;patchm(lat,long,'g')

3、圆锥投影（Conic）。运行下面脚本，依次看到eqaconicstd，eqaconic，eqdconic，lambert，murdoch1，murdoch3六种方案的圆锥投影。close all,clear all,clcload coast %加载海岸线%圆锥投影，有eqaconicstd，eqaconic，eqdconic，lambert，murdoch1，murdoch3等方案subplot(2,3,1);axesm eqaconicstd;patchm(lat,long,'g')subplot(2,3,2);axesm eqaconic ;patchm(lat,long,'g')subplot(2,3,3);axesm eqdconic ;patchm(lat,long,'g')subplot(2,3,4);axesm lambert;patchm(lat,long,'g')subplot(2,3,5);axesm murdoch1;patchm(lat,long,'g')subplot(2,3,6);axesm murdoch3;patchm(lat,long,'g')

5、方位角投影（Azimuthal）。运行下面脚本，依次看到breusing，eqaazim，eqdazim，globe，gnomonic，ortho六种方案的方位角投影。close al造婷用痃l,clear all,clcload coast %加载海岸线%方位角投影，有breusing，eqaazim，eqdazim，globe，gnomonic，ortho等方案subplot(2,3,1);axesm breusing;patchm(lat,long,'g')subplot(2,3,2);axesm eqaazim ;patchm(lat,long,'g')subplot(2,3,3);axesm eqdazim ;patchm(lat,long,'g')subplot(2,3,4);axesm globe;patchm(lat,long,'g')subplot(2,3,5);axesm gnomonic;patchm(lat,long,'g')subplot(2,3,6);axesm ortho ;patchm(lat,long,'g')
