Abstract

A method of processing geo-statistical data includes preparing a data log, extracting acoustic data and coordinate data from the data log, and aligning the acoustic data and the coordinate data. The method also includes cleaning and aggregating the coordinate data, validating the coordinate data geospatially, and creating an output.

preparing a data log of geo-statistical data from a monitoring system using measured parameters that were measured along a pathway;

extracting acoustic data and coordinate data from the data log;

aligning the acoustic data and the coordinate data;

cleaning and aggregating the coordinate data;

validating the coordinate data geospatially; and

creating an output, including;

creating a first contour map including the pathway along which the parameters were measured;

creating a sonar image from the acoustic data; and

displaying simultaneously the contour map and the sonar image.

2. The method of claim 1, wherein the coordinate data is combined with additional coordinate data prior to creating the output.

3. The method of claim 2, wherein the additional coordinate data includes a first set of additional coordinate data and a second set of additional coordinate data.

correlating a water body parameter to each depth range.

6. The method of claim 1, wherein creating the output comprises:

creating the first contour map with a first plurality of depth ranges from the coordinate data; and

creating a second contour map with a second plurality of depth ranges from the coordinate data.

7. The method of claim 6, wherein the first plurality of depth ranges are differentiated by 0.30 meters and the second plurality of depth ranges are differentiated by 0.91 meters.

8. The method of claim 1, wherein creating the output comprises:

creating a polygon on the first contour map; and

analyzing at least one of the acoustic data and the coordinate data within the polygon.

9. The method of claim 1, and further comprising:

changing an altitude at each coordinate by a given value.

10. The method of claim 9, wherein changing an altitude at each coordinate by a given value comprises:

averaging altitude data to obtain an average altitude;

comparing the average altitude to a predetermined value to create an adjustment value; and

adjusting the depth data by the adjustment value.

11. The method of claim 1, and further comprising:

indicating a first position along the sonar image; and

indicating a second position along the pathway that is aligned with the first position along the sonar image.
