Seems I have gotten ahead of myself, I have started posting about things like DTMs and TINs and I have not attempted to explain what they are. For starters, a DTM is a Digital Terrain Model and a TIN is a Triangulated Irregular Network. For the most part, I often use the terms interchangeably but [...]

Occasionally I encounter a set of grading plans with nothing but contour lines as a guide to building a site. Seldom, if ever, does contour lines provide sufficient data to properly establish an accurate DTM from which to work. Allow me a chance to illustrate:

Looks simple and straightforward does it not, put a little more [...]

An area in which I place a great deal of thought these days is in machine control systems. Particularly those systems that are used as grade control for earth moving equipment, such as for dozers, excavators and road graders. This systems function using
1. Some type of positioning systems (usually GPS or Robotics)
2. Device interface (with [...]

There are many ways to approach modeling data and the one I am going to present here I was taught at ETSU in a class called, at the time, Advanced Surveying Mathematics. It is rooted in the realm of Linear Algebra and Calculus and attempts to model data with constraint equations and the minimizing of [...]
