要在osgEarth 3.2中加载TMS高程数据,可以按照以下步骤操作:
1. 首先,在你的应用程序中创建一个osgEarth::Map对象。
2. 在Map对象中添加一个TMSImageLayer图层,并指定图层的URL地址和地图范围。
3. 在Map对象中添加一个TMSHeightFieldLayer图层,并指定图层的URL地址和地图范围。这个图层将加载高程数据。
4. 将Map对象添加到osgEarth::View对象中。
5. 创建一个osgViewer::Viewer对象,并将osgEarth::View对象作为参数传递给viewer的setSceneData()方法。
6. 运行你的应用程序,就可以看到加载的TMS高程数据了。
下面是一个简单的示例代码:
```cpp
osg::ref_ptr<osgEarth::Map> map = new osgEarth::Map();
// 添加TMS图层
osgEarth::Drivers::TMSOptions imagery;
imagery.url() = "http://yourserver.com/tileset";
imagery.profile() = "global-mercator";
osg::ref_ptr<osgEarth::ImageLayer> imageLayer = new osgEarth::ImageLayer("Imagery", imagery);
map->addImageLayer(imageLayer.get());
// 添加TMS高程数据图层
osgEarth::Drivers::TMSOptions elevation;
elevation.url() = "http://yourserver.com/elevation";
elevation.profile() = "global-mercator";
osg::ref_ptr<osgEarth::ElevationLayer> elevationLayer = new osgEarth::ElevationLayer("Elevation", elevation);
map->addElevationLayer(elevationLayer.get());
osg::ref_ptr<osgEarth::View> view = new osgEarth::View();
view->setMap(map.get());
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer();
viewer->setSceneData(view.get());
viewer->run();
```
注意,以上代码中的URL地址和地图范围需要根据你的实际情况进行修改。
