Guidelines 4.1.6. GIS GIS (Geographic Information Systems) can be used to integrate, store, edit, manage and present data which are spatially referenced (linked to location). The data that may be integrated in a GIS include raster images (e.g. digitised historic maps), vector images (e.g. maps captured using drawing software or data captured in the field using electronic measuring instruments), text and numeric data (e.g. databases describing the attributes of a location).
Geographic Information should be created and stored using non-proprietary and open data formats (such as the OpenGIS Geography Markup Language (GML)) and standards maintained by the Open Geospatial Consortium (OGC) and ISO; there are over 40 ISO standards which address a diverse range of functions. Use of proprietary data formats may be appropriate however projects should explore a migration strategy to open formats.
