For a minimal surface, the mean curvature of the surface vanishes for all possible
parameterizations which results in a second‐order nonlinear partial differential equation …

This paper presents a fuzzy system to assure the quality of volunteered geographic
information (VGI) collected for the purposes of species surveillances. The system uses trust …

In this paper, a manner to determine the level sets of a fuzzy surface using the benefits of
Gröbner basis is presented. Fuzzy surfaces are constructed from incomplete datasets or …

The presented research shows how the first derivatives (slope and aspect) can be
calculated from a fuzzy surface by the means of fuzzy arithmetic within the geographic …

The aim of the study is to present utilization of Possibility theory to evaluate soft spatial
queries on Fuzzy Surfaces. Fuzzy Surfaces are constructed from incomplete datasets or from …

When processing spatial information it is very important to maintain the maximum possible
accuracy of positional and attribute characteristics. The level of accuracy is determined by …

Geographic data files describe the real world from different points of view and give a direct
or indirect reference to the geographical location. This data are constantly shared …

Threat of natural or anthropogenic hazards to the transport infrastructure and its vulnerability
to these hazards have always been relevant topics. These issues are crucial in emergency …

Volunteered geographic information (VGI), the information sourced from the platforms for
interactive geospatial data production and consumption fostered by Web 2.0 technologies …
