3D-kataster stavb - pogoj za vstop v tretje tisočletje : 3D Building Cadastre - Condition for Entering the third Millenium
Abstract
SI: Iz sedanje sestave katastra stavb v Sloveniji je razvidno, da se že pojavlja potreba po dopolnitvi evidence o stavbah. Za zdaj na podlagi podatkov katastra stavb ne moremo izdelati popolnega 3D-prikaza stavbe, s tem pa ne dobimo prave predstave o stanju na terenu. Z meritvami, ki jih že sedaj opravljamo geodeti, in morda z nekaj dodatno posnetimi točkami pa se že da izdelati kakovosten 3D-model stavbe. Imamo že izkušnje s področja izdelave 3D-geodetskih posnetkov. Poskusimo poskrbeti še za združitev katastra stavb z zemljiškim katastrom in ju začnmimo uporabljati vzajemno. Zavedati se moramo, da ne živimo več v papirnati dobi in je računalnik postal del našega vsakdanjika. Zato je še kako pomembna tudi višinska komponenta, ki nam zelo olajša orientacijo v prostoru. Sedanja evidenca stavb je bila nedvomno zasnovana kot dobrodošla pomoč pri razumevanju prostora, toda ne pozabimo, da razvoja ni mogoče zajeziti, da je treba spodbuditi razpravo in podpreti razvojne projekte za nadgradnjo. Preprosto se ne smemo zadovoljiti samo z 2D-prostorskimi podatki in nekaj višinami. V članku je podan pregled mednarodnih trendov in možnosti v Sloveniji na področju razvoja 3D-katastra. EN: Concerning the actual structure of the building cadastre in Slovenia, a need to complement our database of buildings is appearing. For now, the information of the building cadastre is not sufficient for the creation of a complete 3D view of a building,which gives us an imperfect image of the condition on the field. With the measurements already being done by the land surveyors, and with a few additional points marked, a high grade 3D model of buildings can be designed. We already have experience with 3D geodeticplans. We should try to combine the building cadastre and land cadastre, and begin to make mutual use of both of them. A change of thinking, i.e. that we do not live in an era of paper, but with computers being part of our everyday life, is necessary. That is why the height component is of great importance, which makes orientation in space much easier. There is no doubt that the present database of buildings was meant as a needed help in understanding space. However, we must not forget that development cannot be stopped and further debate has to be stimulated as developmental projects for the upgrading of the database also have to be supported. Clearly, we must not be satisfied solely with 2D information and some height data. Thispaper gives an overview about international trends and possibilities in Slovenia in the field of 3D cadastre.
