Abstract

The invention relates to the processing of remote sensing data, especially remote sensing data recorded by a satellite. A plurality of processing routines for processing the remote sensing data is available or is prepared. A defined requirement on the use of the remote sensing data is entered by the use of an interface. In a linker, the defined requirement is used to select a certain number of processing routines and to link them together, so that the selected processing routines can process the remote sensing data in such a way that the defined requirement is fulfilled.

Claims

1. A method for selecting remote sensing data, which has been recorded by an airborne or spaceborne sensor, the method comprising:

creating task profile data based upon at least one of a task and goal of use of the remote sensing data which has been recorded by the airborne or spaceborne sensor;

assigning a physical data property to the task profile data to define a requirement on the use of the remote sensing data;

checking data properties of the remote sensing data against the requirement to determine whether and to what degree the requirement can be satisfied by the remote sensing data; and

outputting a result indicating whether and to what degree the requirement can be satisfied.

2. The method of claim 1, further comprising:

creating user profile data describing properties of a user; and

assigning a physical data property to both the task profile data and the user profile data to define a requirement on the use of the remote sensing data.

3. The method of claim 1, further comprising using the requirement to control data processing of the remote sensing data.

4. The method of claim 1, further comprising requesting and loading remote sensing data corresponding to the requirement, and using the requirement to control data processing of the remote sensing data.

The method of claim 1, wherein a physical model describes motion of airborne or spaceborne sensors relative to a surface of an object remotely sensed by the airborne or spaceborne sensors during remote sensing, and wherein the remote sensing data are or have been recorded by at least one of the airborne or spaceborne sensors, and further comprising;

using the physical model in defining the requirement.

6. A method for selecting remote sensing data, comprising:

creating task profile data based upon at least one of a task and goal of use of the remote sensing data;

assigning a physical data property to the task profile data to define a requirement on the use of the remote sensing data;

checking data properties of the remote sensing data against the requirement to determine whether and to what degree the requirement can be satisfied by the remote sensing data;

checking available processing routines operable to process the remote sensing data against the requirement to determine whether and to what degree the requirement can be satisfied by the remote sensing data and the processing routines; and

outputting a result indicating whether and to what degree the requirement can be satisfied.

7. A method for selecting remote sensing data, comprising:

creating task profile data based upon at least one of a task and goal of use of the remote sensing data;
