I have a list of 466 lat/lon-coordinate pairs as follows:
pos = ['52,13','53,15',....,'54,16']
I would like to apply the RDP algorithm in order to reduce this list to just 8 coordinates.
I am using the following code:
length = len(pos)/2
length = int(length)
b = rdp(a.reshape(length, 2))
print (b)
This yields the following error:
TypeError: unsupported operand type(s) for -: 'str' and 'str'
How to resolve the issue that the items in the array are strings ?
