Abstract
Evaluating ground surface hardness for a site involves using a mobile data collection device to automatically drop an object including an accelerometer onto a ground surface at sample locations spaced at regular intervals within the site. The acceleration of the object is detected with the accelerometer as the object impacts the ground surface at the sample locations. A value is generated representative of ground surface hardness for each of the sample locations. Evaluation using a handheld hardness measurement device is also disclosed.
