A method for analyzing geographical regions and detecting areas of interest by a exploration system comprising a sensor and a digital data processing center. The method includes a first phase of learning the intrinsic appearance of each geographical region, in which a database of knowledge comprising groups of digital data is generated. The method further includes a second phase of detecting areas of interest in the geographical regions. The phases includes acquiring a piece of digital data corresponding to a geographical region by the sensor, transmitting the acquired digital data to the digital data processing center, and processing the digital data by the digital data processing center.
Please help me write a proper abstract based on the patent claims. CLAIM: 1-10. (canceled) 11. A method for analyzing geographical regions and detecting areas of interest by digital data processing center and an exploration device comprising a sensor, comprising: a first phase of learning an intrinsic appearance of each geographical region, in which a knowledge base comprising groups of digital data is generated; a subsequent second phase of detecting areas of interest in the geographical regions, the phases comprising the steps of: acquiring a digital data item corresponding to a geographical region by the sensor (311); transmitting the digital data item acquired to the digital data processing center; and processing the digital data item transmitted by the digital data processing center. 12. The method as claimed in claim 11, wherein the step of processing comprises the steps of: recording the digital data item transmitted to the digital data processing center to provide a recorded digital data item; determining a context of obtainment of the recorded digital data item; classifying the recorded digital data item into a group of digital data of the knowledge base having a same context of obtainment as the context of obtainment determined for the recorded digital data item, a set of the digital data of said group of digital data being represented by a statistical model; determining a statistical data on the recorded digital data item; determining a degree of compatibility between the statistical data determined for the recorded digital data item and a statistical data of the statistical model; comparing the degree of compatibility with a predefined threshold; the first phase further comprises the step of updating the statistical model in accordance with the statistical data determined for the recorded digital data item; the second phase further comprises the steps of determining a degree of difference between the statistical data determined for the recorded digital data item and the statistical model, and generating an alert in response to determination that the degree of difference between the statistical data determined for the recorded digital data item and the statistical model is greater than a predefined threshold, the alert indicating the detection of an area of interest. 13. The method as claimed in claim 12, further comprising, after the step of comparing, the step of harmonizing compatibility of the recorded digital data item with the digital data of the group of digital data of the knowledge base. 14. The method as claimed in claim 12, wherein the step of generating, in response to determination that the degree of compatibility is less than the predefined threshold, further comprises the steps of: generating an alert indicating that harmonizing compatibility of the group of digital data is not possible; manually harmonizing compatibility of the recorded digital data item with the digital data of the group of digital data; and automatically harmonizing compatibility of the group of digital data. 15. The method as claimed in claim 12, wherein the context of obtainment of the recorded digital data comprises: a nature of the digital data item, a geographical region corresponding to the digital data item, a viewpoint of the sensor that recorded the digital data item, and a range of resolution of the digital data item. 16. The method as claimed in claim 12, further comprises the step of evaluating a relevance of the alert. 17. The method as claimed in claim 11, wherein the exploration device is included in one of the following: a drone, a helicopter, a balloon, an airplane and a satellite. 18. The method as claimed in claim 11, wherein the sensor is included in one of the following: a camera, a photographic apparatus and a radar. 19. The method as claimed in claim 11, wherein the digital data processing center is remote from the exploration device. 20. The method as claimed in claim 11, wherein the digital data processing center comprises a processing device, a display and input device.
