Developing a Geometry Clipping Algorithm in Java
Suppose we have a polygon and we’d like to clip a section of its boundary a pair of starting and ending coordinates that are very close to the boundary. How are we going to handle that? First, we probably need some function to “snap” the starting and ending points to the polygon boundary. Then we do the clipping with two points that actually lie on the polygon boundary. …

Agent-based Spatial Pattern Modeling Using NetLogo Part 2
I developed this model to simulate simple random motion and biased random motion within constrained space. The major difference with the previous model is that this model loads pre-created GIS data to generate NetLogo data. …
