Abstract: Geographical maps, orthomosaics, 2D/3D models and other photogrammetry products are typically generated from RGB image data. This requires a conversion step from the captured raw format image to RGB. Such conversion can result in image artifacts, blurring and reduction of image resolution, loss of dynamic range, increase in image data size etc. A method is disclosed to avoid conversion into standard RGB image formats at the time of capture and to preserve the full data integrity and image quality all the way through the photogrammetry workflow. Having the raw format image data available at all stages in the workflow will make it possible to extract exactly the data needed at any step in this workflow without compromising the data for other steps. This leads to significant savings in terms of storage space, data transfer bandwidth and processing resource requirements.
