Support To Topology

Use of topological relationships and rules during image classification.

The need of classifying remotely sensed images and characterize the image informative contents in terms of objects and their characteristics is becoming an urgent problem to solve for Earth Observation discipline, especially with the support of automated tools. The more the resolution of satellite sensors increases and the more the level of detail becomes higher and higher; not only the identification and characterization of the smallest possible object that can be detected in one image is important, but also the possibility to correctly group together small objects to create larger and more complex objects is of paramount importance.
The Support to TOpology (STO) project aims at analysing the latter aspect, identifying from users the needs and the methodologies to group together simple objects, and analysing them with experts in the topology domain to verify how the user requests can be satisfied with the theoretical topological approach.

STO is an research project run in the frame of ESA’s Basic Technology Research Programme (TRP). The project consortia is led by SISTEMA GmbH (Austria) having three research partners: UNIAQ (Department of Electrical and Information Engineering of the University of L‟Aquila, Italy), UBA (Austrian Environment Agency) and Gisat.
