The Faculty of Geo-information Science and Earth Observation is a special Faculty of Twente University, partially supported by the Netherlands Ministry of Education, Culture and Science and by the Ministry of Foreign Affairs and was established in 1950.

It is usually referred to as ITC because of its original name: International Training Centre for Aerial Survey.

ITC aims primarily at international education, flanked by research and project services. ITC's training programmes offer some 40 different specialization courses, at postgraduate diploma, master, MSc and PhD levels, and at non-degree level (diploma and short certificate courses).

Since its foundation, ITC has trained more than 20,000 scientists and other professionals from more than 170 countries, thus creating a worldwide network of alumni.

The educational system is international and geared primarily towards mid-career professionals and scientists from developing countries.

ITC's activities concentrate on Geo-information Science and Earth Observation, whereby geo-spatial data collection is predominantly based on aerospace survey techniques.

ITC has six scientific departments, in the fields of: Natural Resources, Water Resources, Earth Systems Analysis, Earth Observation Science, Geo-information Processing, Urban and Regional Planning and Geo-information Management.
