Abstract

Son yıllarda fotogrametrik tekniklerle elde edilen verilerin dijital dokümantasyon projelerinde hızlı bir şekilde sunulması ve paylaşılması büyük önem kazanmıştır. Bu çalışmada, İtalya'nın Padova şehrindeki tarihi öneme sahip Ponte Molino Kapısı’nın dijital dokümantasyonu yapılmıştır. MÖ 40-30 yıllarına tarihlenen bu yapı, bir yersel lazer tarayıcı (TLS) ile taranmış ve kapsamlı bir nokta bulutu oluşturulmuştur. Elde edilen veriler, Potree yazılımı kullanılarak WebGL tabanlı bir ortamda görselleştirilmiş ve çevrimiçi sunum için uygun hale getirilmiştir. Çalışma, Potree’nin nokta bulutu verilerini hiyerarşik bir yapıda işleme ve görselleştirme yeteneklerini, ayrıca kültürel miras varlıklarının sanal ortamda paylaşılması ve etkileşimli olarak incelenmesi için sunduğu avantajları ortaya koymaktadır. Bu yaklaşım, GIS, arazi modelleme ve kentsel planlama gibi alanlarda geniş bir uygulama potansiyeline sahiptir. Çalışmanın sonuçları, Potree’nin nokta bulutu verilerini %80 oranında küçülterek hiyerarşik bir yapıda işleme ve görselleştirme yeteneklerini, ayrıca kültürel miras varlıklarının sanal ortamda paylaşılması ve etkileşimli olarak incelenmesi için sunduğu avantajları ortaya koymaktadır. Sonuçlar, elde edilen verilerin düşük dosya boyutuna indirgenerek çevrimiçi erişilebilir hale getirildiğini ve bu sürecin kültürel mirasın korunması ile erişilebilirliğini %60 daha verimli kıldığını göstermektedir.

Production of WebGL Based Digital Documentation of Ponte Molino Gate From Point Cloud

Abstract

In recent years, the rapid presentation and sharing of data obtained through photogrammetric techniques have gained significant importance in digital documentation projects. This study focuses on the digital documentation of the historically significant Ponte Molino Gate in Padova, Italy. Dating back to 40–30 BC, this structure was scanned using a terrestrial laser scanner (TLS), resulting in the creation of a comprehensive point cloud. The obtained data was visualized using Potree, a WebGL-based software, and prepared for online presentation. The study highlights Potree's capabilities in processing and visualizing point cloud data within a hierarchical structure, as well as its advantages in facilitating the virtual sharing and interactive exploration of cultural heritage assets. This approach demonstrates broad application potential in fields such as GIS, terrain modeling, and urban planning. The results indicate that Potree effectively reduces point cloud data size by 80% while retaining its hierarchical structure, thereby enabling efficient visualization and presentation. The findings also show that the data was reduced to a minimal file size for online accessibility, improving the preservation and accessibility of cultural heritage by 60%.
