1. A method of capturing image data from a scene using a scanning focal plane array (FPA) device that contains at least four banks of Time-Delay and Integration (TDI) detectors, the method comprising: imaging a first portion of the scene with the first TDI bank to create first image data; imaging a second portion of the scene with the second TDI bank to create second image data; imaging the first portion of the scene with a third TDI bank to create third image data; imaging the second portion of the scene with a fourth TDI bank to create fourth image data; warping the third image data to a frame of reference of the first image data; warping the fourth image data to a frame of reference of the second image data; generating first composite image data by combining first and warped third image data; generating second composite image data by combining second and warped fourth image data; warping the second composite image data to a frame of reference of the first composite image data; and combining first composite image data and warped second composite image data into third composite image data.
