INNOVATION IN CADASTRE AND LAND DEVELOPMENT
Agency for Geo-Information
3D Modeling and visualization-city of Hamburg
the goal of this project was to generate a 3D data set including recognizable
buildings and digital terrain models covering all important parts of the city
of Hamburg, and then supply a variety of different data formats to support
different software solutions. However, the agency found that nontechnical
users could not use the data because their hardware performance was
insufficient or their software could not handle the large quantity of data.
To allow the nontechnical users of the data to visualize the 3D model, the
agency used MicroStation to produce PDF files, which can be used without
expensive hardware or software upgrades. Ultimately, the data will be stored
in an object-orientated database that also supports the exchange formats
U3D, DWG, DXF, DGN, and CityGML.
ALSO NOMINATED IN SPECIAL CATEGORY: COMMUNICATING THROUGH VISUALIZATION
Al Ain Town Planning and Survey Sector
Aerial Photography and Satellite Imagery for Mapping of Al Ain
Abu Dhabi, United Arab Emirates
the Al Ain town Planning and Survey Sector is the focal point for spatial data
acquisition, access, and delivery in the eastern region of the Emirate of Abu
Dhabi. The goal of this project was to collect geospatial information from
aerial photography and satellite imagery to produce base maps, orthophoto
maps, digital terrain models, and a virtual representation of the city.
MicroStation was used as a mapping, visualization, and plotting platform,
with which architects, engineers, contractors, and GIS professionals
integrated their maps and as-built drawings of land, buildings, civil
engineering projects, utility networks, and geospatial information. The new
system generates output in formats supported by GIS software and plotting
devices, and the high quality of data produced is encouraging further projects
in data integration.
