Enabling distributed spatial data infrastructures
What is SDI? The definition of Spatial Data Infrastructure (SDI) has changed little since the term first started to be used in the early 1990s: Spatial Data Infrastructure is a “collection of technologies, policies and institutional arrangements to facilitate the availability of and access to spatial data.” This includes cadaster, land administration and land planning applications. Typical components of an SDI have also remained unchanged: (i) a repository of land and spatial data; (ii) a network; (iii) a geographic information system (GIS) for data handling and viewing.
The following white paper discusses SDIs, policiies around them and geospatial technologies available to handle these infrastructures.
