The aim of the project is to identify and categorize urban greenery in order to digitize them. DIgitalization is important for better control and damage prevention of the existing greenery but also so for planning future intervention. By calculating leaf surface, i.e. by inspecting the quantity and quality of urban greenery of the 2 km2 area of municipality Stari Grad, it is possible to determine the existing state, deficienties and future steps in preserving the urban ecosystems. In this case, through the clear numbering of certain categories already identified, it is possible to analyze them in many ways and obtain data that are crucial in the future planning, maintenance, rehabilitation and construction of urban greenery. In the short term such efforts allow cities to better maintain their cities trees and plan new ones. In the long term this is the foundation for various initiatives related to everything from air pollution and public health to climate change and reducing CO2 emissions.
The objectives of this project/study are to check and collect general data about the greenery in the area of 2 m2 in the municipality Stari Grad; to collect various other data related to the greenery; to carry out various activities for developing the basic data; to digitize the data and to create web page for this data. Lack of information leads to the decay and decrease of the plant stock and extinction of valuable biophones that are of multiple importances. During tree inventories for municipalities, institutions, large estates, and the like, knowing tree locations will help managers properly care for a property's plants. When surveying rural roads, nature parks, and hiking trails, managers need to identify and locate hazard trees. Due to rapid urbanization in developing world, city administrators and urban planners are challenged with problems in delivering basic services like green space, sanitation, water supply, transportation, and primary health center. The urban green spaces’ coverage is not adequate to meet people’s needs due to population pressure, expansion of industry, and construction in the process of urbanization. The meaning of the green space system has also been continuously emerging with the development of city theory, which mainly encompasses horticultural, ecological, and spatial meanings.
GIS has the main role in land-use suitability analysis for green space. Older specimens should be protected for use value in breeding and further selection of planting material for further cultivation of city greenery. Information on age and use gives us important data on further valorization and treatment of plant species in urban areas. Benefits of digitization are reflected in timely information about the state of urban greenery, potentials, needs for supplementation and enrichment of biophones. Information on the health condition of trees will serve as a recommendation for rehabilitation. Attention will be given to abiotic harmful effects, snowfall and mechanical damage to trees, as the initial factors of destabilization of their health. It is important to have this information because the importance of urban greenery is reflected in a various way as ambient ecological educational hygienic and health value. Urban planners have to visualize such growth during planning, policy, and de- cision-making. Impulsive construction of unplanned informal houses in and outside the administrative boundaries of towns and cities is common in developing countries. These insightful changes cause a change in land use type which makes urban planning foreseeable.
Data will be collected using GPS technology along with software Arc GIS for digitalization and using Visual Tree Assessment methodology. Data on urban greenery of the 2 m2 (municipality Stari Grad) almost do not exist in the communal enterprise. Because of this, we will carry out on-field inventory and photosets. On-field inventory of the greenery will be done using GPS technology. For the purpose of this project the GPS tracker will be needed. The paper data for the general urban plan and the cadastral data will be scanned and digitized using the software Arc GIS. The GPS receiver is used to collect points for an entire GIS map; this can be accomplished without any aerial photographs or other line and symbol maps to serve as a base map in the GIS. For example, someone collecting data can trace the outline of buildings and parking lots, walk any roads and trails, and take points for trees, signs, and other landmarks. Once the data are in the GIS, the lines and points can be tidied up to improve the visual quality, using different symbols for each landmark. A GIS can produce a simple line and symbol map from the GPS information sufficient for areas with adequate landmarks and where other maps are unavailable. Along rural roads or hiking trails, where maps do not exist and landmarks are scarce, it is possible to walk or drive with a GPS receiver and collect positions for hazard trees and the trails or roads to create a map showing trees that need to be removed.
After collecting and digitizing data and putting online in form of an open source platform, plan is to have this research as a case study presented to the public institutions such as municipalities (Department for Urbanism and Planning), City of Sarajevo, Cantonal Institute for Urbanism, Spatial Planning and Protection of Cultural and Historical Heritage etc. The goal is to encourage the public institutions to use affordable and available technologies in their practice for more accurate and transparent results and more efficient planning.
