Parsing sensor metadata

This example demonstrates opening a raster while parsing image sensor metadata.

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 raster and parse its filename, un-silencing the attribute retrieval to see it printed.

img = gu.open_raster(filename_geoimg)
sensor_metadata = gu.raster.satimg.parse_and_convert_metadata_from_filename(filename_geoimg, silent=False)
img.attrs.update(sensor_metadata)

Setting platform as Landsat 7 read from filename.
Setting sensor as ETM+ read from filename.
Setting tile_name as 140041 read from filename.
Setting datetime as 2000-10-30 00:00:00 read from filename.

We have now retrieved the metadata, stored in the geoutils.Raster.tags attribute.
