CTN 148 - Digital geographic information

Field of Activity:
Standardization of:

The field of digital geographic information. This work aims to establish a structured set of standards, which specifies methods to define, describe and transfer representations of the real world. This makes easier the comprehension and use of the information in the real world referred to the Earth, through coordinates, textual descriptions and codified names.

The intention is to make easier the use, on a wide sense, concerning among others: acquisition, storage, checking, integration, process, analysis, prevention, management and update of digital geographic information, referred to locations relative to the Earth through information technologies. This standardization work will influence and will be influenced by develops within the information technologies.
