Геоінформаційна інвентаризація, оцінювання стану та пропозиції щодо озеленення та благоустрою території парку ім. Івана Франка у Чорткові

The aim of research is to study the phyto and sanitary conditions of green space and the development for its improvement to ensure the appropriate level of further functioning of the park in Chortkiv. The inventory of green space was made in accordance with existing instruction by Technical Greenery Inventory. Plants were determined by conventional methods. To characterize the state of the plant taxations we defined the following parameters: the diameter and height of trees as well as different methods concerning the status of the vitality of plants. The conventional method was used to determine the defectiveness of trees. The criteria for evaluation of the ecological and decorative wood characteristics were as folows: height, trunk diameter, crown diameter and evaluation of vitality. It was used by traditional and modern instruments. The modern were tools were as follows: global positioning device (GPS), geographic information systems (GIS), and methods of remote sensing (on the basis of an orthophotoplan which was obtained with the help of a quadcopter Phantom 4). The data on the location of each tree received via GPS Garmin GPS Map 64S with its subsequent adjustments based on RS Landsat in GIS ArcGis 9.2. After that, GIS database of trees and shrubs was obtained, including coordinates of tree location combined with the information about species, phytosanitary and fundamental taxation features. This enables storing it in a digital format. It gives us opportunity of automated study of the data and displaying them in the form of discrete information on a map. Using these capabilities and digital elevation models, we have created the 3-dimensional digital model of the territory in the license version of RLA2014. After that, to the program layout-creation we put the trees and shrub vegetation according to their location, species and age composition with using of existing GIS database information. The park conditions were analyzed and evaluated considering the phytosanitary, productive and aesthetic conditions. The types of garden landscapes of the object were identified. The analysis of the phytosanitary state of green plantations in Chortkiv Park showed that the vast majority of trees belonged to the category of "good" and almost a quarter of the trees needed to be sanitized or removed.
