Patent ID: 10643098

Abstract:
The invention relates to a system (51) for improving the spatial resolution of sensor data. The system comprises at least one receiver (53) and at least one processor (55). The at least one receiver (53) is configured to receive a sensor data set and a map. Each element of the sensor data set comprises a sensor footprint identifier allowing a sensor footprint to be identified and a brightness temperature measured for the sensor footprint. The map defines for each of a plurality of geographical areas whether it belongs to one of the first class and the second class. The first class represents a land type and the second class represents a water type. The geographical area is smaller than the sensor footprint. The at least one processor (55) is configured to determine for each element of the sensor data set received using the at least one receiver (53) a brightness temperature for each of at least two classes including the first class and the second class based on the map received using the at least one receiver (53) and to determine a brightness temperature for a specific geographical area of the map based on brightness temperatures associated with a plurality of footprints if the specific geographical area belongs to the first class and based on a brightness temperature determined for the second class if the specific geographical area belongs to the second class. Each of the plurality of footprints covers the specific geographical area.
