Apparatus for remote imaging of at least one region of interest, i.e. ROI, in a terrestrial area, the apparatus comprising: a camera array having a focal length f and a photosensor comprising pixels characterized by a pixel pitch P that acquires a sequence of images of the terrestrial area, the images acquired from different 3D spatial locations and camera orientations; an inertial measurement unit, i.e. IMU, and satellite navigation system, i.e. GNSS, receiver that acquire data responsive to the 3D spatial locations and/or orientations of the camera array during acquisition of the sequence of images; a data base comprising an orthographic image and an associated digital terrain map of a terrestrial area wherein the terrain map provides elevation data having an uncertainty Δe that satisfies a constraint P ≥ Δe·f·sinα/A, where A is a maximum distance of the camera array from the terrestrial area and α is a maximum oblique angle at which the camera array images the terrestrial area; and a controller that: registers at least one image of the sequence of images to the orthographic image of the terrestrial area or another image of the sequence of images to determine corrections to the IMU and/or GNSS data; for each ROI of the at least one ROI, uses the corrected IMU and/or GNSS data to crop each image of the sequence to define a portion of the terrestrial image, a ROI cropped image portion, that images the ROI; and registers each ROI cropped image portion to the orthographic image of the terrestrial area using elevation data in the terrain image of the terrestrial area having the uncertainty Δe, using a selection of same landmarks in each of the ROI cropped image portions, to stabilize the ROI cropped image portion to an accuracy equal to or less than the pitch P. a camera array having a focal length f and a photosensor comprising pixels characterized by a pixel pitch P that acquires a sequence of images of the terrestrial area, the images acquired from different 3D spatial locations and camera orientations; an inertial measurement unit, i.e. IMU, and satellite navigation system, i.e. GNSS, receiver that acquire data responsive to the 3D spatial locations and/or orientations of the camera array during acquisition of the sequence of images; a data base comprising an orthographic image and an associated digital terrain map of a terrestrial area wherein the terrain map provides elevation data having an uncertainty Δe that satisfies a constraint P ≥ Δe·f·sinα/A, where A is a maximum distance of the camera array from the terrestrial area and α is a maximum oblique angle at which the camera array images the terrestrial area; and a controller that: registers at least one image of the sequence of images to the orthographic image of the terrestrial area or another image of the sequence of images to determine corrections to the IMU and/or GNSS data; for each ROI of the at least one ROI, uses the corrected IMU and/or GNSS data to crop each image of the sequence to define a portion of the terrestrial image, a ROI cropped image portion, that images the ROI; and registers each ROI cropped image portion to the orthographic image of the terrestrial area using elevation data in the terrain image of the terrestrial area having the uncertainty Δe, using a selection of same landmarks in each of the ROI cropped image portions, to stabilize the ROI cropped image portion to an accuracy equal to or less than the pitch P. registers at least one image of the sequence of images to the orthographic image of the terrestrial area or another image of the sequence of images to determine corrections to the IMU and/or GNSS data; for each ROI of the at least one ROI, uses the corrected IMU and/or GNSS data to crop each image of the sequence to define a portion of the terrestrial image, a ROI cropped image portion, that images the ROI; and registers each ROI cropped image portion to the orthographic image of the terrestrial area using elevation data in the terrain image of the terrestrial area having the uncertainty Δe, using a selection of same landmarks in each of the ROI cropped image portions, to stabilize the ROI cropped image portion to an accuracy equal to or less than the pitch P.
