Abstract

Modern technologies of inventory of green plantations in the city on the basis of remote sensing and mobile laser scanning are considered. The city green fund is the complex economy demanding new approaches, methods of management and technologies of inventory in modern conditions. In the city of Krasnodar (an area of more than 850 km²), amid an unprecedentedly high rate of urbanization, there is a marked change in the structure and composition of green spaces. A necessary condition for the content, protection and reproduction of urban green spaces is to provide information about the green fund. In practice, data are required about the objects of gardening with an accuracy of an individual tree in the park, square, etc.

We solve the problem of creation of information system of green spaces of the municipality on the basis of modern high technology. The technology of mobile laser scanning of urban landscaping objects — parks, squares, gardens, lawns, etc. has been developed. The accuracy of the survey is 3–5 cm, the scanning range is up to 190 m. For the first time in Krasnodar the mobile scanning of green plantations has been done. Mobile laser scanning data are represented by clouds of laser reflection points for each landscaping object. The main result of the work is a geodatabase, including high-precision vector models of municipal landscaping objects (with permission to an individual tree), their attributive description necessary for urban landscaping services. Vector data consist of the following layers: boundaries of the planting site, lawn, trees, old tree wells, young tree wells, shrubs, shrubbery wells, flower beds, mobile objects, other objects, decorative stuff. The received attributive information allows to estimate the costs for the maintenance of each object and the routine works. An information basis for quantitative assessments of the influence of green plantations on the urban climate has been created.

Keywords
