O hartă web a peisajelor Muntelui Vitosha și dezvoltarea științei peisajului în On the first hand, the purpose of this article is to present the map and classification of the landscapes of Vitosha Mountain. On the Bulgaria other hand, it aims to present this map as an example and În primul rând, scopul articolului este acela de a prezenta illustration in the context of traditionally applied approaches in clasificarea peisajelor și harta acestora la nivelul Muntelui Vitosha. Bulgaria in defining the landscape, as well as in researching and Pe de altă parte, lucrarea furnizează harta ca exem-plu și ilustrare classifying the landscapes. There is also a brief overview of the în contextul abordărilor tradiționale utilizate în Bulgaria cu privire development of land-scape science in Bulgaria. la definirea peisajului, precum și în cercetarea și clasificarea The choice of the territory in study relates to the fact that Vitosha peisajelor.

Alegerea arealului de studiu este legată de faptul că Muntele The Vitosha Landscape Map is developed by using GIS tools and Vitosha reprezintă o arie protejată, fiind declarat Parc natural în it is implemented as a web-map, which makes it much easier to 1934, iar în prezent este parte a rețelei Natura 2000. access, examine and work with it, as com-pared to static maps.
