Abstract

3B Kent Modelleri (3BKM) pek çok kent objesinden oluşan yüksek veri hacmine sahip verilerdir. Bu durum 3BKM’lerinin web tabanlı olarak yönetilmesi ve görüntülenmesinde performans sorunları yaratmaktadır. Bu nedenle 3BKM’lerinin bölümlenerek (tiling) daha küçük bölümlere ayrılmaları gerekmektedir. 3D Tiles büyük boyutlardaki 3B veri kümelerinin web üzerinden transferi için tasarlanmış bir spesifikasyon ve OGC standardıdır. 3D Tiles’ın temeli, yalnızca görüntüde görünecek olan bölümlerin web üzerinden transfer edilmesini sağlayan hiyerarşik detay seviyelerine dayanmaktadır. 3BKM’lerinin 3D Tiles spesifikasyonuna göre bölümlenmesini sağlayan herhangi bir açık kaynak kodlu (AKK) web tabanlı yazılım bileşeni bulunmamaktadır. Bu çalışmada 3D Tiles spesifikasyonuna uygun olarak 3B bölümleme yapan web tabanlı açık kaynak kodlu (AKK) yazılım bileşeni geliştirilmiştir. Bölümleme için R-Tree ve Adaptive QuadTree hiyerarşik veri yapıları kullanılmıştır. Üretilen 3B bölümler Cesium.js AKK JavaScript kütüphanesi kullanılarak görselleştirilmiştir. Adaptive Quadtree ve R-Tree veri yapıları 3B bölümleme açısından irdelenmiş, oluşturulma süreleri, veri güncelleme süreleri ve konumsal sorgu performansları karşılaştırılmıştır. Böylelikle geliştirilecek uygulamanın genel özelliklerine göre hangi veri yapısının seçilmesi gerektiği belirlenmiştir.

Abstract

3D City Models (3DCMs) consisting of many city objects are huge in size. This situation causes performance problems in web-based management and displaying of 3DCMs. 3DCMs must be decomposed to smaller data chunks called ”tiles”. 3D Tiles is a specification and OGC standard designed for transferring large 3D datasets over the web. 3D Tiles is based on hierarchical detail levels that allow only the parts that will appear in the image to be transferred over the web. There is no open-source web-based component for tiling 3DCMs according to 3D Tiles. In this study, a web-based 3D Tiling component that tiles 3DCMs according to 3D Tiles has been developed. R-Tree and Adaptive QuadTree hierarchical data structures have been used to decompose 3DCM. Generated 3D tiles have been rendered using open source Cesium.js JavaScript library. Adaptive QuadTree and R-Tree data structures have been investigated in the context of tiling and their performance have been compared in terms of construction times, data update times and spatial query performances. Thus, which data structure should be selected has been determined according to the general characteristics of the application to be developed.
