GIS5935 M1.1: Fundamentals

 

    The map layout above displays the GPS data collected during the field exercise, showing the spatial distribution of recorded points relative to the known reference location. 

    Based on the analysis, the horizontal accuracy was calculated at 3.4 meters, which represents the average distance between the GPS points and the true location. Horizontal precision, measured at the 68 percent threshold, was 4.4 meters, indicating that the majority of points fell within this radius from the mean location. 

    Accuracy reflects how close the data is to the actual target, while precision describes how tightly the points cluster together. These metrics are essential for evaluating the reliability of our and all other GPS data in mapping applications. In this case, the results suggest consistent horizontal performance with low directional bias.
