示例1: ConvertFeatureToRaster
public static void ConvertFeatureToRaster(Layer layer, out Dataset outputDataset, double rasterCellSize, string fieldName)
{
DriverUtils.RegisterGdalOgrDrivers();
Envelope envelope = new Envelope();
layer.GetExtent(envelope, 0);
//Compute the out raster cell resolutions
int x_res = Convert.ToInt32((envelope.MaxX - envelope.MinX) / rasterCellSize);
int y_res = Convert.ToInt32((envelope.MaxY - envelope.MinY) / rasterCellSize);
//Console.WriteLine("Extent: " + envelope.MaxX + " " + envelope.MinX + " " + envelope.MaxY + " " + envelope.MinY);
//Console.WriteLine("X resolution: " + x_res);
//Console.WriteLine("X resolution: " + y_res);
//Create new tiff in disk
string tempRaster = "tempZoneRaster.tif";
if (File.Exists(tempRaster))
{
File.Delete(tempRaster);
}
OSGeo.GDAL.Driver outputDriver = Gdal.GetDriverByName("GTiff");
outputDataset = outputDriver.Create(tempRaster, x_res, y_res, 1, DataType.GDT_Int32, null);
//Extrac srs from input feature

//Geotransform
