Parsing image metadata

This example demonstrates the instantiation of an image through SatelliteImage.

import geoutils as gu

We print the filename of our raster that, as often with satellite data, holds metadata information.

filename_geoimg = gu.examples.get_path("everest_landsat_b4")
import os

print(os.path.basename(filename_geoimg))

LE71400412000304SGS00_B4.tif

We open it as a geo-image, un-silencing the attribute retrieval to see the parsed data.

img = gu.SatelliteImage(filename_geoimg, silent=False)

From filename: setting satellite as Landsat 7
From filename: setting sensor as ETM+
From filename: setting tile_name as 140041
From filename: setting datetime as 2000-10-30 00:00:00

We have now retrieved the metadata. For the rest, the SatelliteImage is a subclass of Raster, and behaves similarly.
