INNOVATION IN CADASTRE AND LAND DEVELOPMENT
The city of Durango, Mexico, entered the digital age with the modernization
of its city council. The objective was to offer better services to citizens by
updating and consolidating geographic information. A photogrammetric survey
of the urban area covered 273 square kilometers. The survey team provided
ground support GPS and aerial triangulation, photogrammetric restitution, and
digital orthophotos for verification of the cadastral data.
About 100 professionals formed work parties in different localities. Bentley
Map and Bentley Geo Web Publisher enabled the parties to work as a
unified team and deliver a uniform work product. Combined with GIS, the
cadastral data map provides accurate information for the city’s operation
and administration, enabling more efficient services at 20 percent less

Digital Map of Prague
Prague, Czech Republic
The Digital Map of Prague is a geographical database for the capital city of the
Czech Republic, which covers about 500 square kilometers. The digital map
combines two sources of spatial information used in public sector GIS projects:
digital cadastral maps and digital technical maps. The system is used internally
for data capture and management and externally for contractors.
The internal system is based on Bentley Map, Bentley PowerMap, Bentley
Geospatial Server, and the Oracle database on Windows, and combines
CAD editing with enterprise GIS features. By capitalizing on these powerful
mapping capabilities, the project team has established a data production line
that can update more than 12,000 building, street, utility connection, and other
infrastructure additions to the city’s digital map annually.
