New Post: Generate contour lines form list of XYZ points

Hi,

I have created a GIS project call www.djupkarta.se where the goal is to create marine maps over Swedish lakes. Today I am using an GUI based application to generate the maps from X,Y,Z points but the project is getting quite large an the amount of data is growing rapidly (When writing about 350miljon XYZ points) so I am about to start to check on how I can automate the procedure.

I got a tool for generating the maps and it takes shape files as input. I wonder if DOT Spatial can convert a list of XYZ points to contour lines?
