Urban Development –

Looking back to the 1960s and

forward to 2020

by Christian Hoffmann, GeoVille Group GmbH

Workshop:

Danube Strategy & Space Technologies

16 June 2011, Brussels

• What can Earth observation contribute?

… the Danube Region accommodates

115 million people living in 14 countries

… satellite derived information offers an

integrated portfolio in the urban domain

… accurate, up-to-date and cost-

effective for

Base inventories

Change monitoring

Scenarios

• Satellites deliver comparable data across

nations …

Starting with LC/LU data

from satellite images …

… combine it with in-situ

data sources …

… to derive value-added

information products

• Satellite data are fully compatible with existing

data and information sources
