Geographic information systems have been applied on the World Wide Web with different approaches and there is a need to recognize how different groups of users conceptualize the domain of geographic space. In our research, we present an attempt to model a semantic reference system in a semantic web by the concept of global geo-ontology. Taxonomy is based on general knowledge representation as physical and conceptual shapes, simultaneously with basic and advanced human activities. Developed ontology includes 588 concepts on five levels and is extendable. Within such a structure, the rules as independence of location, time frame and culture are respected.

This paper presents a proposal for a new numbering of levelling polygons and benchmarks. Furthermore, an accuracy analysis is done with regard to: measured height differences, residuals calculated from differences of the forward and backward runs, residuals from loop closures, and results from network adjustments.

After the floods that hit Slovenia in September 2010, the Institute for Water of the Republic of Slovenia measured the heights of geodetic points (with the GNSS levelling method) used to determine the height of flood water on the Ljubljana moor and Ljubljana. The heights of these points were controlled by trigonometric levelling with connections to the benchmarks of the city levelling network of Ljubljana. An analysis of the accuracy of determining the heights of the points and the differences between the heights of the points, which were determined by GNSS and trigonometric levelling, are presented.

This paper deals with surveying activities in order to define the displacement of the Earth's crust, local displacements of the Earth's surface, and the displacement and deformation of constructed buildings. The determinations of horizontal movements in the terrestrial network, in the terrestrial altitude network and in the GNSS network are dealt with at two levels of accuracy. Geotechnical surveying activities are explained in the paper and demonstrated in the table. The paper Geodesy in geotechnics, published in Geodetski vestnik 54(1), and this paper present an integral whole.

Topographic data, an important part of the National Spatial Data Infrastructure, have been given serious attention since Slovenia's independence. It has become publicly available, updated and harmonised. Financing of topographic data in Slovenia has significantly decreased over the previous decade. As a result, the present status is far from acceptable or expected. The current status of the topographic data, as well as its quality and usability for potential users is discussed in this article. The overview starts with basic source data, aerial surveys, photographs and orthophotos. The quality of orthophotos largely depends on the DTM quality. Topographic data is nowadays organised in thematic datasets (geographical names, building cadastre, etc.) or joined in datasets of different levels of accuracy and details. The status in Slovenia is compared to those in some neighbouring and other comparable countries.

Sports facilities are built objects and outdoor surfaces in the built environment, with significant impacts and effects on society, economy and environment. High-quality sports facilities, their proper spatial distribution and accessibility are important factors in the development of sport and sports-related activities and influence the quality of life. Data on sports facilities and their spatial distribution are a measure for the quality of sports areas. They represent the basis for strategies for the development of sports facilities on local and national levels, their placement in the built environment, and support the development of other sports-related activities. This article highlights the definition of a sports facility and its importance to the built environment and society. The survey includes an analysis of spatial and other databases on sports facilities in Slovenia and an assessment of their quality. A variety of methods and procedures was used to merge and complement the existing databases of sports facilities. The article presents spatial and other analyses and thematic maps of sports facilities by municipalities and statistical regions. It also presents a correlation between the funds Slovenia invested in sports facilities, and the development coefficient of municipalities. Indoor and outdoor sports facilities in individual municipalities are also presented.
