The use of ORFEO ToolBox in the context of map updating

This paper presents experiments with the ORFEO ToolBox (OTB) developed by the CNES in the context of the Brussels project ARMURS about map updating. Depending on the availability of required functionalities, the project either considered the use of OTB or the development of proprietary or open source code. Since the project includes the development of a demonstrator for map updating from image analysis, the different aspects of data format, image processing for remote sensing and graphical interface are key points for the success of the system integration. As OTB addresses these topics, remains opened for extensions and is available as a freeware, it has been envisaged as a possible basic component.
