Projects on creation of spatial data infrastructure in the Russian Federation: a review based on available sources

The analysis of methods used to create the SDI (Spatial data infrastructure), the information technologies for designing the SDI, and the SDI components was carried out.
While analyzing the foreign experience in the SDI creation, the GIS of spatial data of Canada, USA, Australia, Sweden, France, Finland, Spain and other countries, including the implementation of Directive INSPIRE were considered.
It is noted, that in Russia, the creation of SDIs is in an inchoative stage.
The available experience is focused on large regional SDIs.
The analysis of design solutions on the creation of SDI in such Russian regions as the Ural Federal District, Kaluga, Kirov, Samara, Tver, Yaroslavl and other oblasts was performed.
The summary statement reads as follows: the formation of the concept of regional SDI of Altai Krai calls for a new methodological and practical consideration due to the technological advancement in the collection, processing, modeling and presentation of spatial and temporal data as well as the specific character of organization of functioning and services.
The specificity and requirements to regional geoinfrastructurаl model of Altai Krai are formulated.
It is shown that the development and implementation of the regional geoinfrastructural model should specify the composition and the volume of reference spatial data, the status, and the departmental affiliation (property); justify the structure of the regional center of SDI in Altai Krai; develop and coordinate the regulations of interaction between the Altai regional center of SDI (ARC SDI) and the federal center; form the regional structure of the spatial map data layers and the corresponding structure and metadata formats; develop and approve by law the package of normative and legal support of ARC SDI; implement the necessary organizational and economic measures for its development and effective functioning.
The methods of the formation of the regional geoinfrastructural model elements, the set of basic spatial data, the profile and composition of the object metadata are justified.
Automated information data system of state tenement cadastre (AISSTC) may serve as a basis for solving the mentioned tasks.
The structure of spatial data on AISSTC is characterized by efficient dataware that can be used for solving most problems of territory management in Altai Krai.
The system of spatial data can be created and updated via data roll-out from AISSTC in xml format, data conversion into the developed spatial database and complemented by info from other organizations and sources.
The most perspective tools for processing spatial data are ArcGIS software products.
The applications in ArcGIS were developed for auto searching STC appreciable and probable inner topological errors in digital vector maps.
The technology was tested at the detection of errors under making lot plans and their matching with squares and municipal units.
The technique for accuracy evaluation of two- and three dimensional cartographic data and geodetic measurements with the use of mathematical models of spatial location of geographic objects and methods of interval analysis was proposed.
The content of the required source information was defined.
To process this information, the methods for applied interval analysis that allow to obtain point and interval estimates of spatial position of each geoobject were proposed.
The construction of GIS- sites by categories of land resources (including lots for settlements, agricultural lands, lands of aquatic, forest funds and lands of special protected territories) within the SDI framework was suggested.
