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')
