Abstract

Novel tools and techniques might provide for implementing mass haul optimization for agricultural terrain forming, based at least in part on three-dimensional soil modeling. In some embodiments, a computer system might determine desired soil conditions (including minimum topsoil depth, maximum and minimum slope, etc.) for an agricultural area. The computer system might also identify, based on 3-D topographical surveys and 3-D soil profiles, deficient locations within the agricultural area that do not possess at least the minimum topsoil depth, excess locations that possess greater than the minimum topsoil depth, sloped locations that exceed the maximum slope, and/or flat locations whose slopes are less than the minimum slope. Costs and volumes of topsoil and/or subsurface material may be calculated, and based on such calculations it may be determined how much topsoil and/or subsurface material to relocate or order to achieve the desired topsoil depth and slope at the identified locations.

First claim

What is claimed is:

1. A method of land forming for an agricultural area, the method comprising:
creating, with a first computer, a three-dimensional topographic survey for the agricultural area, the three-dimensional topographic survey comprising an outer boundary;
creating, with the first computer, a three-dimensional soil profile for the agricultural area, the three-dimensional soil profile comprising information about topsoil depth throughout the agricultural area within the outer boundary;
determining, with a second computer, desired soil conditions for the agricultural area, the desired soil conditions comprising a minimum topsoil depth for a plurality of locations within the agricultural area;
identifying, with the second computer, one or more deficient locations within the agricultural area that do not possess at least the minimum topsoil depth, based at least in part on the three-dimensional topographic survey and the three-dimensional soil profile;
calculating, with the second computer, a volume of additional topsoil needed to obtain at least the minimum topsoil depth at the one or more deficient locations;
identifying, with the second computer, a plurality of excess locations within the agricultural area that possess greater than the minimum topsoil depth, based at least in part on the three-dimensional topographic survey and the three-dimensional soil profile;
determining, with the second computer, a volume of topsoil to relocate from one or more excess locations of the plurality of excess locations to the one or more deficient locations, based at least in part on an optimization of costs of relocating the volume of topsoil from each of the one or more excess locations to the one or more deficient locations, said optimization is based on a distance between the one or more excess locations and the one or more deficient locations, wherein determining the volume of topsoil to relocate from the one or more excess locations to the one or more deficient locations comprises applying a bulking factor to a volume of topsoil removed from the one or more excess locations;
sending, via the second computer, to at least one earth moving machine, instructions to relocate the determined volume of topsoil from each of the one or more excess locations to the one or more deficient locations; and
relocating, with the at least one earth moving machine, at least part of the determined volume of topsoil from at least one of the one or more excess locations to a respective at least one of the one or more deficient locations, based on the instructions.

2. The method of claim 1 , wherein the three-dimensional soil profile further comprises at least one of runoff coefficient, saturated hydraulic conductivity, consolidated soil composition, top-soil composition, or subsurface soil composition.

3. The method of claim 1 , wherein the optimization of costs of relocating the volume of topsoil from each of the one or more excess locations to the one or more deficient locations is based at least in part on the distance between each of the one or more excess locations and the one or more deficient locations.

4. The method of claim 1 , wherein the optimization of costs of relocating the volume of topsoil from each of the one or more excess locations to the one or more deficient locations is based at least in part on costs of relocating the volume of additional topsoil needed to obtain at least the minimum topsoil depth at the one or more deficient locations.

5. The method of claim 1 , wherein the optimization of costs of relocating the volume of topsoil from each of the one or more excess locations to the one or more deficient locations is based at least in part on earth-moving equipment costs.

6. The method of claim 1 , wherein the optimization of costs of relocating the volume of topsoil from each of the one or more excess locations to the one or more deficient locations is based at least in part on a cost of acquiring at least a portion of the volume of additional topsoil needed to obtain at least the minimum topsoil depth at the one or more deficient locations from a location outside of the agricultural area.

7. The method of claim 1 , wherein calculating the volume of additional topsoil needed to obtain at least the minimum topsoil depth at the one or more deficient locations comprises applying, with the second computer, a shrinkage factor to the volume of additional topsoil to add to the one or more deficient locations.

8. The method of claim 1 , further comprising:
identifying, with the second computer, a location to stockpile topsoil being relocated from the one or more excess locations to the one or more deficient locations, based at least in part on optimization of costs to stockpile topsoil.

9. The method of claim 1 , further comprising:
determining, with the second computer, a maximum allowable cost to obtain at least the minimum topsoil depth throughout the agricultural area; and
wherein determining the volume of topsoil to relocate from the one or more excess locations to the one or more deficient locations comprises determining, with the second computer, a volume of topsoil to relocate from the one or more excess locations to the one or more deficient locations, based at least in part on the maximum allowable cost to obtain at least the minimum topsoil depth throughout the agricultural area.

10. The method of claim 1 , wherein the three-dimensional soil profile for the agricultural area further comprises at least one of a depth to bedrock, a depth of subsurface material between the topsoil and the bedrock, interior elevation measurement points, or manual elevation measurement points.

11. The method of claim 10 , wherein the desired soil conditions for the agricultural area further comprises a maximum slope; and wherein the method further comprises:
identifying, with the second computer, one or more sloped locations within the agricultural area that exceeds the maximum slope; and
calculating, with the second computer, a volume of subsurface material to relocate to obtain a slope that is less than the maximum slope at each of the one or more sloped locations.

12. The method of claim 11 , further comprising:
identifying, with the second computer, a location to stockpile the volume of subsurface material for relocating to or from each of the one or more sloped locations, based at least in part on the three-dimensional topographic survey and the three-dimensional soil profile.

13. The method of claim 11 , further comprising:
identifying, with the second computer, a location to stockpile topsoil when the volume of subsurface material is relocated to or from each of the one or more sloped locations, based at least in part on the three-dimensional topographic survey and the three-dimensional soil profile.

14. The method of claim 11 , wherein calculating the volume of subsurface material to relocate to obtain a slope that is less than the maximum slope at each of the one or more sloped locations comprises calculating, with the second computer, a volume of subsurface material to relocate to obtain a slope that is less than the maximum slope at each of the one or more sloped locations, based at least in part on an optimization of costs to relocate the volume of subsurface material.

15. The method of claim 10 , wherein the desired soil conditions for the agricultural area further comprises a minimum slope; and wherein the method further comprises:
identifying, with the second computer, one or more flat locations within the agricultural area that do not have at least the minimum slope; and
calculating, with the second computer,
