% with another multi-million point flight line would be very slow. 

%% Example: Intersection of snowmobile track with grounding line
% Here we'll grab (very approximate) grounding line data from <https://www.mathworks.com/matlabcentral/fileexchange/60246 Mouginot et al> and
% see where it intersects a snowmobile track given by four waypoints:
