1. An aerial camera system comprising: a camera cluster including a plurality of cameras, wherein each camera is oriented in a direction selected from a plurality of different camera directions having a downward component; three rotators, each rotator configured to rotate the camera cluster about a respective axis of rotation in response to one or more signals, wherein a first rotator of the three rotators is configured to change an orientation of the camera cluster about a vertical axis and a second rotator of the three rotators is configured to change the orientation of the camera cluster about a horizontal axis; and a control module configured to (a) provide one or more signals to cause the first rotator of the three rotators to rotate the camera cluster about the vertical axis; (b) to successively: (i) provide a signal to the second rotator of the three rotators to rotate the camera cluster thereby changing the orientation of the camera cluster about the horizontal axis, and (ii) cause cameras in the camera cluster to acquire respective aerial images; (c) repeat steps (a) and (b). 2. The system of claim 1, wherein the camera cluster comprises one or more cameras configured to capture oblique views. 3. The system of claim 2, wherein the control module is configured to adjust the oblique angle of the one or more cameras configured to capture oblique views. 4. The system of claim 2, wherein the camera cluster comprises two cameras configured to capture oblique views and at least one camera configured to capture a downward looking nadir view. 5. The system of claim 4, wherein the camera cluster further comprises a camera configured to capture data in the near-infrared portion of the electro-magnetic spectrum of a downward looking nadir view. 6. The system of claim 1, wherein the control module is configured to cause one of the rotators to rotate the camera cluster about a vertical axis to correct for situations in which an aircraft carrying the camera system may be pointed in a direction differing from its direction of travel due to the presence of cross winds. 7. The system of claim 1, wherein the control module provides motion correction to reduce image blur resulting from motion of the plane over the ground. 8. The system of claim 1, further comprising a GPS/imu module configured to encode data, associated with captured images, pertaining to one or more of position, velocity, and attitude. 9. The system of claim 8, further comprising a bundle adjustment software module configured to improve the accuracy of the data pertaining to one or more of position, velocity and attitude associated with a given image. 10. The system of claim 9, further comprising a synthetic frame image creation software module configured to create a synthetic frame image from a collection of images and associated data corresponding to one or more of position, velocity and attitude. 11. A method of controlling a camera cluster including a plurality of cameras, wherein each camera is oriented in a direction selected from a plurality of different camera directions having a downward component, comprising: (a) providing one or more signals to cause a first rotator to rotate the camera cluster about a vertical axis;(b) successively for each time of a sequence times: (i) providing a signal to a second rotator to rotate the camera cluster changing an orientation of the camera cluster about a horizontal axis, and (ii) causing cameras in the camera cluster to acquire respective aerial images; and(c) repeating steps (a) and (b). 12. The method of claim 11, further comprising: (a) using the camera cluster to acquire one or more oblique aerial images of an area; and,(b) using the camera cluster to acquire one or more images of a downward looking nadir view of the area. 13. The method of claim 12, further comprising using the camera cluster to capture data in the near-infrared portion of the electro-magnetic spectrum of a downward looking nadir view. 14. The method of claim 11, further comprising rotating the camera cluster about a vertical axis to correct for situations in which an aircraft carrying the camera cluster may be pointed in a direction differing from its direction of travel due to the presence of cross winds. 15. The method of claim 11, further comprising using a GPS/imu module to encode data, associated with captured images, pertaining to one or more of position, velocity, and attitude. 16. The method of claim 15, further comprising using a “Bundle Adjustment” software module to improve the accuracy of the data pertaining to one or more of position, velocity and attitude associated with a given image. 17. The method of claim 16, further comprising using a synthetic frame image creation software module to create a synthetic frame image from a collection of images and associated data corresponding to one or more of position, velocity and attitude.
