Unified spectral and geospatial information model and the method and system generating it

摘要

This invention relates to a product called unified spectral and geospatial information model and the method and system that generates the model. Here, the model comprises an airborne image of ground surface. The image in such a model has three-dimensional XY2 coordinates for every pixel of it and particularly multiple pixels of the image can have same XY coordinates. The XYZ coordinates of all the pixels of the image are uniquely attributed by the method and system presented in this invention. An image of the unified spectral and geospatial information model always covers a scene of ground surface. And, all objects visible in such a scene are measurable in terms of both radiometry and geometry. The unified spectral and geospatial information model can be made by the method and system of this invention with airborne imagery, GPS/IMU data, and ground surface elevation or range data.
