The RADIUS Common Development Environment has been designed to combine
information from a variety of sources to support the construction of a site model: imagery,
terrain data, wire frame model. In doing so, the system is made of a mix of manual and
automatic construction methods (without mentioning the systems developed by IRIS). The
user can start by loading an image into a blank pane and can performed some operations as
contrast stretch, enhance. To begin building a model, the user creates a view transform�…
