I'm working on a project that involves using linear interpolation to fit lines to lat/lng points. I'm pretty new at scientific programming related stuff, and I was wondering if people could steer me in the right direction.What is a good tutorial for linear interpolation in Python, preferably using GIS data?

Could you clarify what you mean by fitting lines to lat/long points? What values are you trying to predict, and are you trying to estimate values between measured locations, or just account for the geographic locations? –  Jay Guarneri Nov 16 '13 at 23:16

While it doesn't mention GIS data specifically, you might try reading "Python for Data Analysis" by Wes McKinney. This is a good introduction to the premiere tools for (generic) data analysis in Python: NumPy and Pandas.
