Abstract
Incorporating detailed 3D building data into national spatial data infrastructures (SDI) is associated with numerous technical and administrative challenges. This paper presents and discusses the challenges that have emerged within recent 3D mapping initiatives in Slovenia. The increasing availability and affordability of LiDAR and photogrammetric technologies have enabled the automated generation of comprehensive 3D building datasets. Despite these technological advancements, several difficulties arise in integrating these datasets with existing cadastral and topographic databases. Primary challenges include discrepancies in spatial accuracy, outdated building outlines, semantic inconsistencies, and varying classification methodologies among datasets. Moreover, maintaining these integrated datasets is complex due to differing update cycles across cadastral and topographic systems. Cadastral data requires rigorous administrative processes for updates, while 3D modelling of buildings typically relies on automated procedures. Additionally, the legal status of cadastral data further complicates the integration. The challenges identified in the case of Slovenia can largely be generalised to systems in other countries, highlighting the necessity for strategic planning in data integration processes, considering both technical specifications and administrative frameworks, to use the full potential of 3D building data within national SDIs

Abstract:
Vključevanje podrobnih 3D-podatkov o stavbah v nacionalne prostorske podatkovne infrastrukture (SDI) je povezano s številnimi tehničnimi in administrativnimi izzivi. Ta članek predstavlja in obravnava izzive, ki so se pojavili v okviru nedavnih pobud za 3D-kartiranje v Sloveniji. Naraščajoča razpoložljivost in cenovna dostopnost lidarskih in fotogrametričnih tehnologij je omogočila avtomatizirano ustvarjanje celovitih 3D-naborov podatkov o stavbah. Kljub temu tehnološkemu napredku se pojavlja več težav pri integraciji teh naborov podatkov z obstoječimi katastrskimi in topografskimi bazami podatkov. Glavni izzivi vključujejo razlike v prostorski natančnosti, zastarele obrise stavb, semantične nedoslednosti in različne metodologije klasifikacije med nabori podatkov. Poleg tega je vzdrževanje teh integriranih naborov podatkov zapleteno zaradi različnih ciklov posodabljanja v katastrskih in topografskih sistemih. Katastrski podatki zahtevajo stroge administrativne pos topke za posodobitve, medtem ko 3D-modeliranje stavb običajno temelji na avtomatiziranih postopkih. Poleg tega pravni status katastrskih podatkov še dodatno otežuje integracijo. Izzive, ugotovljene v primeru Slovenije, je mogoče v veliki meri posplošiti na sisteme v drugih državah, kar poudarja potrebo po strateškem načrtovanju v procesih integracije podatkov, pri čemer je treba upoštevati tako tehnične specifikacije kot administrativne okvire, da se izkoristi polni potencial 3D-podatkov o stavbah v nacionalnih SDI.
