Geographic information is a huge volume of cartographic and geographic data, which is represented by the records, coordinates and attributes. According to the Handbook [2], geographic information is fractal with very simple geometric properties, is fuzzy, because it models a part of the physical world, is very dynamic, due to the rate of change, is unique and it contains errors. The most often medium, which displays geographic information is map, no matter if it is in analogue or digital form. The whole production...

The long-term effect of economic development in post-communist Romanian urban areas brought exponential growth in motorization and uncontrolled urban expansion. As Romanian authorities still adopt conventional transport management policies, urban traffic congestion in the city of Cluj-Napoca has become a main contributor to noise pollution and air quality degradation, and has negative effects on the economy and social activities. Given the analysis of the structural and functional characteristics of the city of Cl...

Border effect is a phenomenon that adversely affects the development of the regions. It involves the suppression of links between centers, which limits the development of the areas between these centers. Each type of boundary is generating variously powerful border effect, which can be quantified as the ratio between the expected and actual power of spatial interactions. Expected power of spatial interactions is calculated on the basis of geographic application of the gravity model, calibrated by using data on dai...

In this contribution, the authors describe a novel method of visualizing any 3D object into a 2D seamless picture with the use of cartographical principles. The method uses properties of a sphere with reflective inner surface, in which a 3D object and capturing camera are placed. A sphere surface is consequently unfolded using cartographic projection allowing to see the whole object in 2D. The method can be applied to any objects, preferably those of non-human origin, e.g. trees with leaves, cave systems, EarthпїЅ...
