Hansa Luftbild Saves 20 Percent on Cadastre System Development Expenses Using Bentley Map - 1

CASE STUDY Project Summary Organization Hansa Luftbild AG Solution Government Location Addis Ababa, Ethiopia Project Objectives • Update the cadastral map of Addis Ababa, Ethiopia. • Support establishment of municipal real property registration offices. • Develop a modern property registration and land information system to address rapid urban expansion, slum settlement, and land and property rights. • Analyze requirements for a real property registration and land information system. • Design, develop, and implement these systems. Products Used Bentley Map, MicroStation Fast Facts • Bentley Map was selected as the foundation of the cadastral project. • Persistent topology, in combination with comprehensive CAD and GIS functionality, ensured the required data quality and consistency. • Photogrammetric data capture was carried out in MicroStation’s 3D environment. • A total of 360,000 parcels and 1.15 million building or construction features were mapped. Bentley Map Saves Hansa Luftbild 20 Percent on Cadastre System Development Expenses Addis Ababa City Administration Implements Custom Property Registration and Land Information System Built on Bentley Map Clarifying Property Rights A member of the Bentley Developer Network, the Hansa Luftbild Group, Muenster, Germany, offers public- and private-sector clients expertise in the areas of geoinformation and geospatial problem-solving. The City of Addis Ababa, Ethiopia, retained Hansa Luftbild to develop a modern property registration and land information system to address rapid urban expansion, slum settlement, and land and property rights. A major part of the EUR 3 million project was to develop a service-oriented architecture (SOA) based on industrystandard components. Bentley Map was implemented at the client layer to maintain and administer the cadastre map data and descriptive information for 360,000 parcels and 1.15 million building or construction features in a 520-square-kilometer area. The software’s integration with .NET and open API saved nearly two man-months, or 20 percent, in development time. Addressing Urban Expansion In 1996, the Addis Ababa City Government implemented a cadastral project to register all property owners so that properties could be valued and taxed. A multi-purpose cadastre was established and data collected to support urban planning, land and property transfers, the issuing of building permits, and compensation payments. Eventually the combination of Over time, rapid urban expansion in the capital city put pressure on land resources and contributed to the growth of slums, informal property settlement, land encroachment, and inadequately secured land records. In response to these challenges, the City initiated a new housing redevelopment program that required a reliable, consistent records-keeping system for real property rights and ownership. The Addis Ababa City Administration (AACA) committed to securing and clarifying land and property rights, and promoting the use of proper transaction processes through registration. An up-to-date cadastral map and robust geo-database system was critical to achieving these goals. AACA retained Hansa Luftbild to develop a modern property registration and land information system based on efficient business processes. The contract included supporting the setup of a real property registration agency, drafting the necessary legal framework, and updating existing cadastral data. A major part of the project was the development and implementation of technical infrastructure to support cadastral processes. The system incorporated the principles of CADASTRE 2014 (International Federation of Surveyors) and implemented a data model derived from the ISO Land Administration Domain Model. Service-oriented Architecture ROI • Using Bentley Map saved up to two man-months, or 20 percent, of development time for Hansa Luftbild. • The Addis Ababa City Administration achieved an up-to-date cadastral map and geodatabase system that will help to create legal certainty and help to attract foreign investors to put capital into local business. insufficient integration between the various land information systems and inefficient updating mechanisms led to a significant erosion of the cadastral map’s reliability. To meet the specific requirements of the local cadastre administration, Hansa Luftbild applied a SOA based on industrial standard components such as Bentley Map, Oracle Spatial, Microsoft ASP.NET and Windows Communication Foundation. Considering the limited telecommunication infrastructure available in parts of the city, the project team designed a distributed solution. Comprehensive CAD and GIS functionality provided the perfect base for handling cadastral data and ensuring data quality and consistency. Hansa Luftbild implemented the system with a central cadastral database, decentralized sub-city databases, and client-level implementations. The installation in the sub-cities
