Abstract

A computer-implemented method for processing images to identify Energy Infrastructure (EI) features within aerial images of global terrain is provided. The image processing method identifies information about EI features by applying an EI feature recognition model to aerial images of global terrain. The EI feature recognition model identifies the EI feature information according to image content of the aerial image. The method further provides updates to the identification of the EI feature information according to relationships between identified EI features.

Claims

1. A computer-implemented method for processing images to identify Energy Infrastructure (EI) features, the method to be carried out by at least one processor executing computer instructions, the method comprising:

receiving a working image comprising at least one aerial image of a portion of global terrain;

applying an EI feature recognition model to the working image to identify a first EI feature at a first confidence level according to image content of the working image;

associating the first EI feature with a first EI feature type and a first location within the portion of the global terrain;

retrieving an identification of a second EI feature in the portion of the global terrain;

associating the second EI feature associated with a second EI feature type and a second location within the global terrain;

updating the identification of the first EI feature to a second confidence level based at least on the first confidence level, the identification of the second EI feature, and information on a relationship between the first EI feature and the second EI feature.

2. The computer-implemented method of claim 1 wherein the identification of the second EI feature includes a third confidence level.

3. The computer-implemented method of claim 2, wherein updating the identification of the first EI feature to the second confidence level is further based on the third confidence level.

4. The computer-implemented method of claim 1 wherein updating the identification of the first EI feature to the second confidence level is further based on the first EI feature type and the second EI feature type.

5. The computer-implemented method of claim 1 wherein updating the identification of the first EI feature to the second confidence level is further based on the first location and the second location, or a distance therebetween.

6. The computer-implemented method of claim 1 wherein the first EI feature type and the second EI feature type are members of a set of EI feature types including one or more of:

an EI development site;

a frac-water pit, frac pond or frac water impoundment,

7. The computer-implemented method of claim 1 wherein the EI feature recognition model is a first EI feature recognition model, the method further comprising applying a second EI feature recognition model to a working image to retrieve the identification of the second EI feature according to image content of the working image.

8. The computer-implemented method of claim 7, further comprising generating the first EI feature recognition model by training a neural network to recognize EI features of the first EI feature type and generating the second EI feature recognition model by training a neural network to recognize EI features of the second EI feature type.

9. The computer-implemented method of claim 1, further comprising retrieving the identification of the second EI feature from a supplemental information source, the supplemental information source including information on at least one of:

10. The computer-implemented method of claim 9 wherein the supplemental information source is a public records information source or an EI feature database.

11. The computer-implemented method of claim 1, further comprising updating a database of EI features with a data record including:

the first location,

the first EI feature type.

12. The computer-implemented method of claim 11 wherein updating the database of EI features is conditional on the second confidence level meeting or exceeding a predetermined confidence threshold.

13. The computer-implemented method of claim 11 wherein the data record includes the second confidence level.

14. The computer-implemented method of claim 11 further comprising identifying a status attribute of the first EI feature, and wherein the data record includes the status attribute.

15. The computer-implemented method of claim 14 wherein the status attribute includes one or more of:
