Resource information
Administrators and politicians are beginning to recognize spatial information as a national re source as well as a part of the basic infrastructure that needs to be efficiently coordinated and managed in the interest of the nation. It is very important to develop policies for standardization, legal aspects, pricing, distribution, etc. Spatial Data Infrastructure is conceived to be: an umbrella of policies, standards and procedures under which organisations and technologies interact to foster more efficient use, management and production of spatial data. The FIG Commission 3 has on the background of a number of Country Reports and presentations compiled a list of "Experiences and Visions" on Spatial Data Infrastructure. Even though the "Experiences and Visions" is not based on scientific work or investigations it contains valuable information on the developing trends and challenges.
