GDAL-java读取tiff文件信息

ReadTiff.java代码:

package Raster;

import org.gdal.gdal.Band;
import org.gdal.gdal.Dataset;
import org.gdal.gdal.Driver;
import org.gdal.gdal.gdal;
import org.gdal.gdalconst.gdalconstConstants;

public class ReadTiff {
    public static void main(String[] args) {
        gdal.AllRegister();

        String rasterFilePath = "E:\\Test\\TestOpenLayers\\data\\GF1_PMS2_E121.7_N39.9_20170609_L1A0002429674_Fusion.tiff";

        Dataset dataset = gdal.Open(rasterFilePath,
                gdalconstConstants.GA_ReadOnly);
        if (dataset == null) {
            System.out.println("GDAL read error: " + gdal.GetLastErrorMsg());
        }

        Driver driver = dataset.GetDriver();
        System.out.println("driver short name: " + driver.getShortName());
        System.out.println("driver long name: " + driver.getLongName());
        System.out.println("metadata list: " + driver.GetMetadata_List());

        int xsize = dataset.getRasterXSize();
        int ysize = dataset.getRasterYSize();
        int count = dataset.getRasterCount();
        String proj = dataset.GetProjection();
        Band band = dataset.GetRasterBand(1);

        // 左上角点坐标 lon lat: transform[0]、transform[3]
        // 像素分辨率 x、y方向 : transform[1]、transform[5]
        // 旋转角度: transform[2]、transform[4])
        double[] transform = dataset.GetGeoTransform();
        for(int i=0; i<transform.length; i++){
            System.out.println("transform: " + transform[i]);
        }
    }
}
