Approaches to mapping complex green zone of the city

The purpose of this article is to generalize and systematize approaches to the mapping of the complex green zone of the city, taking into account all its structural and functional elements. Main material. In the course of the research, four approaches to mapping of the complex green zone of the city have been proposed and substantiated: structural, territorial, functional and integral. Structural approach apprehends mapping of land use structure of complex green zone of the city. The territorial approach is based on the mapping of main territories of the complex green zone of the city legislatively defined in Ukraine. The functional approach is based on mapping of structural elements of the complex green zone of the city according to the priority of their functional purpose. The functional approach is considered to be easy and practical to apply. The integral approach covers all aspects of the previous three approaches and is a summarizing tool for mapping important functional-spatial elements of the complex green zone of the city. The study also analyzes current approaches to the use of innovative technologies in the creation of electronic mapping materials and geoportals of the city green zone. Such approaches have been found not to be of wide practical use and require additional research. Conclusions and further research. The analysis of the existing theoretical works and practical developments made it possible to generalize and systematize approaches to the mapping of the complex green zone of the city, identifying four main ones: structural, territorial, functional and integral. In the conditions of modern innovative technologies, electronic mapping of the complex green area of the city begins to develop. Therefore, we propose to represent generalized and systematic information on the interactive map of the complex green zone of the city, including: cores, green corridors, local greening areas and green belt around the city. This approach optimizes an interactive map legend and simplifies the process of visualization of functional-structural elements in the complex green zone of the city. The prospect of future research remains to monitor the use of these approaches and to develop an algorithm for creating an interactive map of the complex green zone of the city.
