Yakubailik. <...> The Formation of Regional Spatial Data Infrastructure 1. <...> Introduction Spatial data is digital data concerning spatial objects, including information on their location and features, on their spatial and non-spatial attributes. <...> Spatial data is data on geographical objects, which represents the formalized digital models of material or abstract objects in the real or virtual world. <...> A representation of spatial data, or a model of spatial data is a way of a digital representation of spatial objects, or a type of a structure of spatial data. <...> Spatial data can be represented as regular network, as well as vector and attributive models. <...> Within a regular network model the whole territory that is being explored is divided into the elements of a regular network, or cells, and is subdivided into raster models and GRID-models by value type. <...> Metadata databases, including those comprised in cartographic data and geoinformational systems, can provide a medium of inventory <...>
