I can't imagine anyone would find this interesting but myself, however something came across my desk the other day that was sort of relevant to this. We needed to simplify closed, non-linear...

@Vinvar - Some of your assumptions are incorrect. The first and last points should *never* be culled. They are critical in defining the geometry and removing Point 6 in your example turns it from...

My data set was entirely linear point geometry like OP's. The threshold I used was originally hard coded but after field testing we used the rendering time and number of culled points to adjust the...

Ah terrific question! One of the best I've seen for a long time. This happens to be very close to me because I've recently be trying to optimise shape files for use on a tablet.

My solution was...
