cad模型数据输出为kml文件
要将Java中的坐标转换为KML文件格式,您可以使用Java KML库,如JAK库。以下是一个示例代码,可将WGS84坐标转换为KML格式,并将其导出到KML文件:
```java
import de.micromata.opengis.kml.v_2_2_0.*;
public class KMLExporter {
public static void main(String[] args) {
// Create a new KML document
Kml kml = new Kml();
// Create a new placemark
Placemark placemark = KmlFactory.createPlacemark();
// Set the placemark name
placemark.withName("My Placemark");
// Set the placemark description
placemark.withDescription("This is my placemark");
// Create a new point with WGS84 coordinates
Point point = KmlFactory.createPoint()
.withCoordinates(new Coordinate(-122.0822035425683, 37.42228990140251, 0));
// Set the placemark geometry to the point
placemark.withGeometry(point);
// Add the placemark to the KML document
kml.createAndSetPlacemark().withName(placemark.getName())
.withDescription(placemark.getDescription())
.withGeometry(placemark.getGeometry());
// Export the KML document to a file
KmlMarshaller.marshal(kml, new File("my_placemark.kml"));
System.out.println("KML file exported successfully!");
}
}
```
在上面的示例中,我们使用了JAK库来创建一个新的KML文档,并将一个名为“My Placemark”的点添加到其中。点的坐标是经度为-122.0822035425683,纬度为37.42228990140251,高度为0的WGS84坐标。最后,我们将KML文档导出到名为“my_placemark.kml”的文件中。
请注意,您需要在项目中包含JAK库的JAR文件以运行此代码。
