Re: [JPP-Devel] split tool

Hi Erwan. Do you want a tool or a plugin? A plugin (menu item) might
be better -- it would iterate over your whole dataset - no manual user
intervention required.

How many contour lines and how many features do you have? Hundreds, or
tens of thousands?

Here's one approach:

for each hydro line
 find list of intersections with contour lines
 for each intersection
   break hydro line
   get contour line z
   set z on coordinate on the 2 smaller hydro lines
