With the pressure of the increasing density of urban areas, some public infrastructures are moving to the underground to free up space above, such as utility lines, rail lines and roads. In the big data era, the three-dimensional (3D) data can be ben

Since 2014, the Land Survey Division of Singapore Land Authority (SLA) has spearheaded a Whole-of-Government (WOG) 3D mapping project to create and maintain a 3D national map for Singapore. The implementation of the project is divided into two phases

From underground utility survey to land administration: An underground utility 3D data model

Publikováno v: Land Use Policy, 102

Subsurface utility infrastructure is omnipresent in the often highly contested shallow layers of the subsurface of densely urbanised areas. Reliable information on the location of such utilities is pivotal for the planning and management of such spac

Cadastral spatial units around the world range from simple 2D parcels to complex 3D collections of spaces, defined at levels of sophistication from textural descriptions to complete, rigorous mathematical descriptions based on measurements and coordi

We demonstrate an approach to the formalization of user actions in the human-computer interaction literature [18]. for the purpose of producing task-oriented ontologies. Verbs and nouns are extracted from a document that depicts user actions during a
