This assignment will take a file (text) containing the latitudes of airports in Kansas and convert them to degrees. The converted data will be output to an external text file. You will then us another text file which contains the (x,y) coordinates of 12 airports in Kansas and determine the nearest neighbor to each airport. This data will be used to plot a graph of all airports and their relative locations.
Write a function FileDMS2FileDD(dmsFile, ddFile), which reads the latitudes in
text file dmsFile, converts them into decimal degrees, and saves the decimal degrees to the text file ddFile. The text file dmsFile has four columns that are separated by space. The first column is the names of the points and the other 3 columns are the latitudes in degrees, minutes and seconds respectively. The output text file ddFile should have two columns. The first column is the names of the points and the second column is the decimal degrees of the points. You can use the latitudes of twelve Kansas airports in the file KansasAirportLatitudesInDMS.txt to test your function.
Write a function NearestNeighbor(pointsFile, nnpointsFile), which finds the nearest
neighbors for the points in the text file pointsFile and writes the nearest neighbor
information to the text file nnpointsFile. The text file pointsFile has three columns that are separated by comma. The first column is the unique IDs of the points and the other two columns are the x and y coordinates of the points respectively. The output text file
nnpointsFile also has three columns and separated by comma. The first column stores the IDs of the points. The second column stores the IDs of their nearest neighbors and the third column stores the distance to their nearest neighbors. You can use the points in file
Points.txt to test your function.
Using the data file created in the previous function create a plot of the positions of each airport (see example plot).
