matlab kmlread函数代码

以下是 MATLAB 中 kmlread 函数的示例代码：

% 读取 KML 文件
kmlFilePath = 'path/to/kml/file.kml';
kmlStruct = kmlread(kmlFilePath);

% 获取 KML 结构体中的信息
name = kmlStruct.Document.Name;
description = kmlStruct.Document.Description;
placemarks = kmlStruct.Document.Placemark;

% 遍历所有的 Placemark
for i = 1:length(placemarks)
    placemark = placemarks(i);
    placemarkName = placemark.Name;
    placemarkDescription = placemark.Description;
    placemarkGeometry = placemark.Geometry;

    % 处理不同类型的几何体
    if isa(placemarkGeometry, 'kmlPoint')
        % 处理点
        pointCoordinates = placemarkGeometry.Coordinates;
        % ...
    elseif isa(placemarkGeometry, 'kmlLineString')
        % 处理线
        lineCoordinates = placemarkGeometry.Coordinates;
        % ...
    elseif isa(placemarkGeometry, 'kmlPolygon')
        % 处理多边形
        outerBoundaryCoordinates = placemarkGeometry.outerBoundaryIs.LinearRing.Coordinates;
        innerBoundaryCoordinates = placemarkGeometry.innerBoundaryIs.LinearRing.Coordinates;
        % ...
    end
end

请注意，此示例代码中的 `kmlFilePath` 变量需要替换为实际的 KML 文件路径。
