On topography.npy you can find a Digital Elevation Map of the Neuquén Basin
area: from 73°W to 65°W and 41°S to 33°S; obtained from
Ryan et. al. (2009).
The data is saved as a 2d array into a binary file with the NumPy .npy format.
To access the information you must do it using the numpy.load() function.
The first two columns contain the latitude and longitude points, respectively;
while the third column has the elevation data (in meters).
For example, we can access the information with the following script:
import numpy
data = numpy.load("topography.npy")
lat, lon, topo = data[:, 0], data[:, 1], data[:, 2]
On sediment_thickness.dat you can find the Neuquén Basin thickness, obtained
by digitalizing the maps in
Heine, C. (2007).
The data is saved in an ASCII file, divided in three columns containing the
latitude, longitude and sediment thickness points.
They can be read in Python using the numpy.loadtxt() function:
import numpy
lat, lon, thickness = numpy.loadtxt("sediment_thickness.dat", unpack=True)
