Laser Scanning in Connecticut Surveys

No matter if part of the coastline along the Atlantic or the hilly areas of Litchfield County are being mapped, Connecticut surveys incorporate tried-and-true and modern techniques. Surveying, for boundary or civil engineering purposes, is the technique of determining two- or three-dimensional points on the surface of the Earth and the angles between them. These points are used to establish land maps and boundaries. In addition to the technical aspects involving geometry, trigonometry, and engineering techniques, Connecticut surveys need research and observations, taking into account and historical documents or records for the area.

Measuring all points, however, is a time-consuming process and takes time away from surveyors that need to be conducting research. Laser scanning, however, is one technique that speeds up this process. Used for many Connecticut surveys, this technique captures these points on the surface of the Earth with beams of light. In addition to speeding up the surveying process, the device also makes capturing complex and difficult to reach surfaces easier.

Used commonly for civil and structural engineering, a laser scanner sends out a point of light in the direction of an object being surveyed. The scanner, then, times the light from the moment it leaves to when it reaches the object to when it returns, and this figure becomes a point on a three-dimensional graph (X, Y, and Z). The laser scanner continues sending out thousands of beams in the direction of the object, and a point cloud is formed on the three-dimensional graph. Once all the points in the cloud are connected together, the scanner calculates the angles between each of the points, and a three-dimensional, computerized image forms.

At this point, however, the survey is not complete. Although the physical data from an object or land has been gathered, two-dimensional images are needed for many engineering projects. The three-dimensional image on the laser scanner can be traced from several angles in order to make two-dimensional drawings.

Reverse Engineering Q&A Session


This video is a question and answer session. It covers the questions that I have been asked since I posted my first Reverse Engineering video. This video does not cover some of the basics that you may need to know in order to understand it. If you can’t follow this video then I advise you to check out my first Reverse Engineering video on episode 2 of Weekend Warriors. The questions that are answered in this video are: 1)What is an entry point? 2)What is the original entry point? 3)What does it mean for a executable to be packed? 4)What is a portable executable? 5)How do you know if a Portable Executable is packed or protected? 6)How do you know if you are at the Original Entry Point (OEP) or not ? 7)How do you find the original entry point? 8)How do you beat debugger checks? 9)How do you get around spending hours tracing through code? 10)What do we do after we find the OEP?
