Low Pass Javascript

As part of the runsat work, I've had a continual battle to get elevation results "realistic"

This is particularly challenging because of "noise" in the sampled elevation data.

The latest attempt at this, has been to use a low pass filter - based on work at - to smooth the elevation data.

You can see the effect:


  1. This looks really good, do you still have the source for it? The link is no longer active

    1. The source is still out there on runsat somewhere... dig around and you may find it (although it used v2 google maps api)
