The path below was also generated by the form using
this GPX file, but the parameters
are set to verySmall=0.0008, numLevels=9,
and zoomFactor=4. The choice of verySmall
is not small enough; as a result, you can see changes in the line
as the zoom level changes. Furthermore, only 450 points are actually
encoded, due to the high threshold in the Douglas-Peucker algorithm.
Note that changes in the detail of the line occur about every other
zoom level, due to the choices of numLevels and
zoomFactor.
