如何将空间参考保存到由 node-gdal 创建的 GeoTIFF？

Question

我正在尝试使用 node-gdal 创建 GeoTIFF 并为其设置空间参考。空间参考来自现有文件并编写如下代码

// read an existing file and get its spatial reference
let dataset = gdal.open(filePath);
this.bandData = dataset.bands.get(1);
this.rasterSize = dataset.rasterSize;
this.geoTransform = dataset.geoTransform;
this.spatialReference = dataset.spatialReference;

// save the same spatial reference to a new file
let driver = gdal.drivers.get('GTiff');
let dataset = driver.create(filePath, this.rasterSize.x, this.rasterSize.y, 1, gdal.GDT_Byte);

let bandData = dataset.bands.get(1);
bandData.pixels.write(0, 0, this.rasterSize.x, this.rasterSize.y, data);

dataset.spatialReference = this.spatialReference;
dataset.geoTransform = this.geoTransform;
dataset.flush();

但是，当我用QGIS加载保存的文件时，它提示GeoTIFF没有任何投影信息。

可以找到完整代码HERE。

Answer 1

这显然是一个错字:-(

this.spatialReference = dataset.spatialReference;

应该是

this.src = dataset.src;
