Hansa Luftbild submitted a paper about their “Addis Ababa Land Administration System” and was awarded with an “Honorable mention” in the category “Innovation in Government”, the second highest honour. A big success if you compare the budget of our € 3 Mio. with the winner’s budget, Europe's largest railway and infrastructure construction project “Crossrail” in London with projected costs of €18 billion.
The Addis Ababa Land administration system was implemented on top of Bentley Map. One of the outstanding features of Bentley Map, the persistent topology, was the main reason why we decided to use this application as the foundation of our cadastral project. Its persistent topology in combination with the comprehensive CAD and GIS functionality is the perfect base for handling cadastral data and insure the required data quality and data consistency. To update and complete the data coverage of Addis Ababa, new digital aerial photography was acquired for the entire project area, covering 520 square kilometer city area of Addis Ababa, including all ten sub-cities and 116 districts. The photogrammetric data capture in a 3D-stereo environment was carried out on a Bentley Microstation V8i.
The integrated cadastre functionality of Bentley Map was used and tailored to the specific needs of the data model in Addis Ababa. As a result, 359.897 parcels were generated in total and the number of building or construction features mapped was 1.145.690. Our outstanding experience in the development of software solutions for Bentley MicroStation and Bentley Map over the last two decades makes Hansa Luftbild a strong and reliable partner for training in and consulting for Bentley software products.
