我想将rasterio
窗口导出到图像。
import rasterio
def export_window(w, path):
number_of_bands, height, width = w.shape
profile = {
"driver": "JPEG",
"count": number_of_bands,
"height": height,
"width": width,
'dtype': 'uint8'
}
with rasterio.open(path, 'w', **profile) as dst:
dst.write(w)
不幸的是,由于我没有在上面的 profile
中指定 transform
键,因此收到以下警告:
>>> raster = rasterio.open("/tmp/geo.tif")
>>> w = raster.read(window=rasterio.windows.Window(0, 0, 500, 500))
>>> export_window(w, "/tmp/export.jpg")
NotGeoreferencedWarning: Dataset has no geotransform set. The identity matrix may be returned.
有没有办法从rasterio
窗口导出非地理引用图像而不收到警告?
最佳答案
您需要设置转换,如果将其设置为身份,警告就会消失:
import rasterio
def export_window(w, path):
number_of_bands, height, width = w.shape
profile = {
"driver": "JPEG",
"count": number_of_bands,
"height": height,
"width": width,
'dtype': 'uint8',
'transform': rasterio.Affine(1, 0, 0, 0, 1, 0),
}
with rasterio.open(path, 'w', **profile) as dst:
dst.write(w)
