Matlab绘制中国地图超全教程详解

目录

• 各省边界线绘图
• 省份填色图
• 中国公路交通图
• 中国铁路交通图
• 中国河流图
• 组合美化图
• 美化图一
• 美化图二

依旧需要用到Mapping Toolbox不会安装的可以看我上一篇

虽然我们只读取shp文件，但需要保证文件夹里还有shx文件及dbf文件

各省边界线绘图

provinces=shaperead('bou2_4l.shp','UseGeoCoords',true);

% 绘图
worldmap('China');
geoshow(provinces)

省份填色图

provinces=shaperead('bou2_4p.shp','UseGeoCoords',true);

% 绘图
worldmap('China');
faceColors=makesymbolspec('Polygon',{'INDEX',[1 numel(provinces)],'FaceColor',polcmap(numel(provinces))});
geoshow(provinces,'DisplayType','polygon','SymbolSpec',faceColors)

改个颜色：

provinces=shaperead('bou2_4p.shp','UseGeoCoords',true);

% 插值定义颜色
C=[222,238,209;126,190,174;144,213,220;
    33,118,155;30,69,128;20,49,127]./255;
C1(:,1)=interp1(0:5,C(:,1),linspace(0,5,numel(provinces)),'linear')';
C1(:,2)=interp1(0:5,C(:,2),linspace(0,5,numel(provinces)),'linear')';
C1(:,3)=interp1(0:5,C(:,3),linspace(0,5,numel(provinces)),'linear')';

% 绘图
worldmap('China');
faceColors=makesymbolspec('Polygon',{'INDEX',[1 numel(provinces)],'FaceColor',C1});
geoshow(provinces,'DisplayType','polygon','SymbolSpec',faceColors)

标注省份名称

provinces=shaperead('bou2_4p.shp','UseGeoCoords',true);

% 插值定义颜色
C=[222,238,209;126,190,174;144,213,220;
    33,118,155;30,69,128;20,49,127]./255;
C1(:,1)=interp1(0:5,C(:,1),linspace(0,5,numel(provinces)),'linear')';
C1(:,2)=interp1(0:5,C(:,2),linspace(0,5,numel(provinces)),'linear')';
C1(:,3)=interp1(0:5,C(:,3),linspace(0,5,numel(provinces)),'linear')';

% 绘图
worldmap('China');
faceColors=makesymbolspec('Polygon',{'INDEX',[1 numel(provinces)],'FaceColor',C1});
geoshow(provinces,'DisplayType','polygon','SymbolSpec',faceColors)

% 读取首都和省级行政中心位置信息并标记
pnames=shaperead('res1_4m.shp','UseGeoCoords',true);
for i=1:numel(pnames)
    textm(pnames(i).Lat,pnames(i).Lon,pnames(i).NAME, ...
   'HorizontalAlignment','center','FontSize',5,'color','k')
end

单独绘制某个省份：

worldmap([42,55],[120,137]);

% 从中国省份数据文件中获取黑龙江省
P=shaperead('bou2_4p.shp','UseGeoCoords',true,...
  'Selector',{@(name) strcmp(name,'黑龙江省'),'NAME'});
patchm(P.Lat,P.Lon, [0.5 0.7 0.5])

中国公路交通图

borders=shaperead('bou1_4p.shp','UseGeoCoords',true);
roads=shaperead('roa_4m.shp','UseGeoCoords',true);
worldmap('China');

geoshow(borders,'FaceColor',[239,238,234]./255)
geoshow(roads,'Color',[250,227,158]./255,'LineWidth',1.5)

中国铁路交通图

borders=shaperead('bou1_4p.shp','UseGeoCoords',true);
rails=shaperead('rai_4m.shp','UseGeoCoords',true);
worldmap('China');

geoshow(borders,'FaceColor',[239,238,234]./255)
geoshow(rails,'Color',[.2,.2,.2],'LineWidth',1,'LineStyle','-.')

中国河流图

borders=shaperead('bou1_4p.shp','UseGeoCoords',true);
riversp=shaperead('hyd1_4p.shp','UseGeoCoords',true);
riversl=shaperead('hyd1_4l.shp','UseGeoCoords',true);
worldmap('China');

geoshow(borders,'FaceColor',[239,238,234]./255)
geoshow(riversp,'FaceColor',[127,141,181]./255,'EdgeColor',[127,141,181]./255)
geoshow(riversl,'Color',[127,141,181]./255,'LineWidth',1)

组合美化图

  'Selector',{@(name) strcmp(name,'Africa and Eurasia'), 'Name'});
patchm(antarctica.Lat, antarctica.Lon, [0.5 0.7 0.5])
