Development of soil compaction analysis software (SCAN) integrating a low cost GPS receiver and compactometer.

Hwang J, Yun H, Kim J, Suh Y, Hong S, Lee D - Sensors (Basel) (2012)

Bottom Line: The SCAN is distinguished from other previous software for intelligent compaction (IC) in that it can use the results from various types of GPS positioning methods, and it also has an optimal structure for remotely managing the large amounts of data gathered from numerous rollers.For this, several methods were developed: (1) improving the accuracy of low cost GPS receiver's positioning results; (2) modeling the trajectory of a moving roller using a GPS receiver's results and linking it with the data from the compactometer; and (3) extracting the information regarding the compaction states of the ground from the modeled trajectory, using spatial analysis methods.The SCAN was verified throughout various field compaction tests, and it has been confirmed that it can be a very effective tool in evaluating field compaction states.

ABSTRACT
A software for soil compaction analysis (SCAN) has been developed for evaluating the compaction states using the data from the GPS as well as a compactometer attached on the roller. The SCAN is distinguished from other previous software for intelligent compaction (IC) in that it can use the results from various types of GPS positioning methods, and it also has an optimal structure for remotely managing the large amounts of data gathered from numerous rollers. For this, several methods were developed: (1) improving the accuracy of low cost GPS receiver's positioning results; (2) modeling the trajectory of a moving roller using a GPS receiver's results and linking it with the data from the compactometer; and (3) extracting the information regarding the compaction states of the ground from the modeled trajectory, using spatial analysis methods. The SCAN was verified throughout various field compaction tests, and it has been confirmed that it can be a very effective tool in evaluating field compaction states.

f5-sensors-12-02351: Algorithm for converting point objects to continuous quadrangle cell objects.

Mentions: Figure 5 shows the algorithm of converting point objects to cell objects using two steps. First, the azimuth angles perpendicular to the connect lines between the first and second point and between the second and third point were calculated. Next, the average of the two azimuths to determine the azimuth of the second point was configured. This process was iterated to calculate each azimuth for every point.
