Landsat raster file I/O
An open-source Python package for simple loading of Landsat imagery as NumPy arrays. When downloading Landsat imagery from USGS Earth Explorer, the datasets contain many bands (.tif files) and a few metadata files (.txt and .xml files). espatools is built to parse the .xml metadata file to read all of the bands for that dataset and provide a convenient and intuitive means of accessing that metadata along side the raw data in a Python environment. espatools can be found on GitHub and PyPI.
espatools is available from PyPI
$ pip install espatools
We think espatools is easy to use; give it a try and let us know what you think as this is just the alpha-release!
- First, take a look at this example for PVGeo where espatools has an interface for direct use in ParaView.
- Then checkout this Jupyter Notebook for a demonstration of some simple plotting after reading Landsat imagery in a Python environment.
Example False Color
import espatools import matplotlib.pyplot as plt # Create the reader to manage I/O reader = espatools.RasterSetReader(filename='metadata.xml') # Perform the read and yield a raster set raster = reader.read() # Get an RGB color scheme color = raster.get_rgb('false_a') # Now plot the false color image plt.imshow(color)
The results of the above code yield the following false color image:
