Summary

Description
English: This is a plot produced from Shuttle RADAR Topography data for the vicinity of the Parinacota volcano.
Date
Source

I am the original author of the program that produced this image. The data source was Height Map File S19W070.hgt from the United States Geological Survey SRTM database.

The program that produced this image is written in Python with the matplotlib toolkit:

#!/usr/bin/env python
try:
	import numpy
	import matplotlib.pyplot
	import pylab
	import sys
except ImportError as err:
	print("ERROR : required python libraries are not properly installed")
	print(err)
	quit()

input_file = sys.argv[1]
print("Opening File: " + input_file)

datatype = numpy.dtype('>i2')           #16-bit big-endian data 

e1=1201			# Height
e2=1201			# Width

size=e1*e2*datatype.itemsize
shape=(e1, e2)

#data = np.zeros(shape)
data = numpy.fromfile(input_file, datatype, size)
data = data.reshape(shape)

fig1 = pylab.figure(1)
imgplot = matplotlib.pyplot.imshow(data)
imgplot.set_cmap('gray')
imgplot.set_clim(2000,6400)
imgplot.set_interpolation('nearest')		# 'bilinear' , 'bicubic', 'nearest'

matplotlib.pyplot.colorbar()
matplotlib.pyplot.show()


pylab.savefig('output.png')
