Abstract:
1. A method of evaluating ground surface hardness for a site, the method comprising: collecting acceleration data using a ground surface hardness measurement device including a movable sensor by dropping the movable sensor onto a ground surface at sample locations within the site; generating a plurality of values, each value representative of ground surface hardness for each of the sample locations based on the acceleration data; generating, using at least one computing device, a single score for at least a portion of the site based at least in part upon the plurality of values for the sample locations, the single score at least partially representative of a ground surface hardness of the at least a portion of the site; and segmenting the site into at least two regions, including at least one higher activity region and at least one lower activity region; and weighting the values representative of ground surface hardness for the at least one higher activity region more heavily than the values for the at least one lower activity region, wherein generating the single score uses the weighted values.
