Precision site characterization using digital twin
Subject soils are classified using a sensing tool. By profiling each of a number of first locations that have a ground truth classification, using a deployed sensing tool, digital soil properties of new locations without ground truth classifications can be obtained to determine corresponding classifications for the new locations. This allows information related to classifications to be utilized for optimal use of the new locations.
1. A method of characterizing soil properties of a subject soil located in an unmapped, wrongly mapped, or minimally mapped geographic location, wherein the subject soil does not have an associated or correct predefined and known soil classification, the method comprising:
deploying a sensing tool to a plurality of first geographic locations in differing classified soils that each have a corresponding predefined and known soil classification, wherein the sensing tool includes a plurality of sensors of differing types each configured to be responsive to one or more soil properties;
obtaining, at each of the plurality of first geographic locations, first depth varying raw signal outputs from the plurality of sensors at each of the plurality of first geographic locations;
creating for the first depth varying raw signal outputs from each of the plurality of first geographic locations, a corresponding first digital signature;
deploying the sensing tool to the subject soil at a second geographic location;
obtaining, at the second geographic location, second depth varying raw signal outputs from the plurality of sensors at the second geographic location;
creating for the second depth varying raw signal outputs from the second geographic location, a corresponding second digital signature;
comparing the second digital signature of the subject soil to the first digital signatures of the classified soils; and,
determining, based on the comparing and on the corresponding predefined and known soil classifications of the plurality of first geographic locations, a characterization of the subject soil at the second geographic location.
2. The method of claim 1 , wherein the characterization of the subject soil comprises a first soil property.
3. The method of claim 1 , wherein the characterization of the subject soil comprises a first soil classification.
4. The method of claim 1 , wherein the characterization of the subject soil comprises a first soil site characterization.
5. The method of claim 1 , wherein each predefined and known soil classification is a reference soil series and the characterization of the subject soil is a corresponding soil classification.
6. The method of claim 5 , wherein the determining includes computing for the second digital signature a closest matching signature from among the first digital signatures of the classified soils, the classification for the second geographic location being determined as the predefined reference soil series of the closest matching signature.
7. The method of claim 6 , wherein the closest matching signature is computed by curve comparison.
8. The method of claim 1 , further comprising storing the first digital signatures in a database.
9. The method of claim 1 , wherein the first and second depth varying outputs of the plurality of sensors of the sensing tool are recorded continuously in a given timeframe.
10. The method of claim 1 , wherein the sensing tool is a multi-sensor penetrometer.
11. The method of claim 1 , wherein each predefined and known classification of the classified soils and the characterization of the subject soil are a level of classification chosen from a Soil Taxonomy classification system.
12. The method of claim 1 , wherein each first digital signature is created for a combination of at least two of the first depth varying raw signal outputs, and the second digital signature is created for a combination of at least two of the second depth varying raw signal outputs.
13. A system for characterizing soil properties of a subject soil located in an unmapped, wrongly mapped, or minimally mapped geographic location, wherein the subject soil does not have an associated or correct predefined and known soil classification, the system comprising at least one processor configured to perform the method of claim 1 .
14. The system of claim 13 , wherein each first digital signature is created for a combination of at least two of the first depth varying raw signal outputs, and the second digital signature is created for a combination of at least two of the second depth varying raw signal outputs.
15. The system of claim 13 , wherein the characterization of the subject soil comprises a first soil classification.
16. The system of claim 13 , wherein each predefined and known soil classification is a reference soil series and the characterization of the subject soil is a corresponding soil classification.
17. The system of claim 16 , wherein the determining includes computing for the second digital signature a closest matching signature from among the first digital signatures of the classified soils, the classification for the second geographic location being determined as the predefined reference soil series of the closest matching signature.
