Dev. Highlights from the past: After the fall of the iron curtain • International cooperation • Scholarships in „western” countries (USA, Canada, Italy…) already in the ’80s • EARSeL membership (1990, first post-socialist country) • EARSeL Symposium (1992, Eger) • ISPRS Comm. VII ECO BP (1998, Budapest) • Cooperation with the Joint Research Centre (JRC) • Expeditions • Hungarian Space Office (HSO/MŰI) founded in 1992 • Coordination of space-related activities • RS/EO is one of the five main areas • ESA cooperation: PRODEX / PECS programmes • Cooperation among Hungarian institutions • Inclusion of RS in university studies • Main drivers: • Agricultural applications • Environmental applications CROPMON(NÖVMON) crop area (ha) 1 000 1 200000 1 400000 200 000 400 000 600 000 800 000 -
