Determination of some tree parameters using terrestrial laser scanner in urban green areas

Abstract: The aim of this study is to measure the parameters for modelling individual and street trees in urban areas using Terrestrial Laser Scanner (TLS) data. Breast height diameter (d1.30), tree height, crown base height, distance between trees were measured in the roadside trees which are composed of Narrow-leaved ash (Fraxinus angustifolia Vahl.) in Istanbul University Faculty of Forestry Campus. In addition, tree zone models of the trees were formed in order to express development process of trees with time in an integrated way and to make connections among different parts of trees. As a result of measurements, d1.30valuesvaried between 24 cm and 45,6 cm both from ground measurement and TLS. Statistically there were not a significant difference between d1.30 values, even though ground measurement values were higher than TLS measurements. According to regression analysis, a significant correlation was found between ground and TLS mesurements (R2=0,971, p<0,05). Objective values were derived from TLS data related to tree crown forms, tree zone model and tree architecture. The ratio of static and dynamic mass of trees and their relations were showed on 3D tree models. 3D tree models and measurements on this models, which were carried out in this study, can be used in maintenance and pruning application of individual and forests of Urban areas.

Keywords: Terrestrial laser scanner, individual tree parameters, tree model

Yersel lazer tarayıcı sistemler ile kentsel yeşil alanlarda bazı ağaç parametrelerinin belirlenmesi

Özet: Bu çalışmada, Yersel Lazer Tarayıcı (YLT) kullanarak kentsel ortamlardaki bireysel ve alle şeklinde ağaçların modellenmesine yönelik parametlerin ölçülmesi amaçlanmıştır. Çalışma alanı olarak İstanbul Üniversitesi Orman Fakültesi kampüsü içerisinde yer alan Dar yapraklı dişbudak (Fraxinus angustifolia Vahl. ) yol bölümü seçilmiştir. Çalışma kapsamında ağaçların göğüs yüksekliği çapı (d1.30), boyu, yaş dal yüksekliği, ağaçlar arasındaki aralık ve mesafe ölçümleri gerçekleştirilmiştir. Bununla birlikte ağaçların zamana göre değişimlerini bir bütün olarak açıklamak ve farklı bölümleri arasında bağlantılar kurmak amacıyla ağaç zonları modeli oluşturulmuştur. Ölçümler sonucunda ağaçların d1.30 çap değerleri hem YLT hemde yersel ölçüm tekniğine göre 24 cm ile 45,6 cm arasında değişim göstermiştir. İstatistiki analiz sonucunda yersel ölçüm ile elde edilen d1.30 çap ortalaması YLT ölçüm değerlerinden yüksek olmasına rağmen ölçümler arasında anlamlı fark bulunamamıştır. Regresyon analizi sonucuna göre Yersel ölçüm ile YLT ölçümleri arasında anlamlı doğrusal ilişki olduğu ortaya çıkmıştır (R2=0,971, p<0,05). YLT sistemle yapılan taramalardan elde edilen verilerden ağaçların tepe formları, ağaç zonları modeli ve ağaç mimarisiyle ilgili objektif veriler türetilmiştir. Statik ve dinamik kitle oranları ve bunların ilişkileri 3 boyutlu (3B) ağaç modeli üzerinde ortaya konmuştur.

Anahtar Kelimeler: Yersel lazer tarayıcı, bireysel ağaç parametreleri, ağaç modeli
