Generating a series of random points <br />over the areas in question using <br />ArcGIS 10.X <br />2. Developing a field form for adding <br />measured topsoil depth for each point <br />sampled. <br />3. Navigating to a subset of the points <br />generated using a Panasonic tough pad <br />GPS unit. <br />4. Auguring the soil to the depth where <br />resistance was noted. <br />5. Determining by visual and tactile <br />inspection of soil sample (color, <br />texture, particle size) if the spoil layer <br />had been reached. <br />6. Laying the handle of a shovel across <br />the hole at its diameter. <br />7. Measuring with a tape from the bottom <br />of the hole to the bottom of the shovel <br />handle/surface of soil for topsoil depth. <br /> <br /> <br /> <br />Illustration 2: (lower left), the 11 topsoil <br />sampling locations showing the topsoil depth profile. <br />Yellow represents the shallowest range at 9.25 to 9.5; and <br />darkest brown represents the range of 15 to 17.5 inches of <br />topsoil. <br /> <br />
