Analiza podatkovnih baz o mestnih zelenih povr inah kot izhodi e za razpravo o povezavi med kakovostjo in uporabnostjo podatkov : Analysis of green areas databases as a starting point of discussion on relation between quality and usefulness of data

V prispevku je predstavljena zveza med kakovostjo in uporabnostjo podatkov o mestnih zelenih povr inah na primeru Mestne ob ine Ljubljana. Izhodi e za razpravo je teza, da nekriti no zbiranje podatkov ovira u inkovitost urejanja zelenih povr in. V raziskavi so zajeti podatki iz razli nih doma ih in tujih virov, na podlagi katerih se poka e, da obstajajo precej nje razlike med posameznimi zbirkami podatkov o zelenih povr inah v Ljubljani. Namesto univerzalnih podatkov, na primer o koli ini vseh mestnih zelenih povr in, se ka ejo razlike, ki izhajajo iz namena in na ina zbiranja ter vsakokratne interpretacije pojmov in pojavov. Kot je razvidno iz analize, je uporabnost takih specifi nih podatkovnih zbirk zelo omejena, podatki v njih so lahko zavajajo i, kar lahko posredno negativno vpliva na urejanje zelenih povr in. V razpravi na koncu je izpostavljeno, da je vir te av z upravljanjem, varstvom in razvojem zelenih povr in pomanjkanje enotnih, splo no veljavnih izhodi , kot so opredelitve pojmov in pojavov ter dogovorov o ciljih urejanja zelenih povr in ; This article highlights the quality and usefulness of data on urban green areas in the Municipality of Ljubljana case study. The starting point of the discussion is the thesis that uncritical data collection hampers the effectiveness of managing green spaces. The survey includes data from various Slovenian and foreign sources and shows that there are significant differences between different Ljubljana green area databases. It reveals differences arising from the purposes and methods of data collection and respective concepts and phenomena interpretation, rather than universal data, such as the quantity of urban green spaces. The case study shows that such specific databases have very limited usefulness and that their information may be misleading. Furthermore, they can be indirectly harmful for the managing of green spaces. The discussion at the end of this paper shows that the source of the problems with the management, protection and development of green areas is a lack of uniform, generally applicable starting points, such as definition of the concepts and phenomena and agreements on the managing aims of green spaces.
