Study of City Landscape Heritage Using Lidar Data and 3d-City Models

Abstract

Commission VI, WG VI/4KEY WORDS: Urban Landscape Protection, LIDAR Data, 3D City Models, CityGML, Computational Urban Analysis, Tall Buildings ABSTRACT:In contemporary town planning protection of urban landscape is a significant issue. It regards especially those cities, where urban structures are the result of ages of evolution and layering of historical development process. Specific panoramas and other strategic views with historic city dominants can be an important part of the cultural heritage and genius loci. Other hand, protection of such expositions introduces limitations for future based city development. Digital Earth observation techniques creates new possibilities for more accurate urban studies, monitoring of urbanization processes and measuring of city landscape parameters. The paper examines possibilities of application of Lidar data and digital 3D-city models for: a) evaluation of strategic city views, b) mapping landscape absorption limits, and c) determination protection zones, where the urbanization and buildings height should be limited. In reference to this goal, the paper introduces a method of computational analysis of the city landscape called Visual Protection Surface (VPS). The method allows to emulate a virtual surface above the city including protection of a selected strategic views. The surface defines maximum height of buildings in such a way, that no new facility can be seen in any of selected views. The research includes also analyses of the quality of simulations according the form and precision of the input data: airborne Lidar / DSM model and more advanced 3D-city models (incl. semantic of the geometry, like in CityGML format). The outcome can be a support for professional planning of tall building development. Application of VPS method have been prepared by a computer program developed by the authors (C++). Simulations were carried out on an example of the city of Dresden.

Utilization of Large Scale Surface Models For Detailed Visibility Analyses

“…The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-2/W8, 2017 5th International Workshop LowCost 3D -Sensors, Algorithms, Applications, 28-29 November 2017, Hamburg, Germany presented by Czyńska and Rubinowicz (2017), Rubinowicz and Czyńska (2015), Wrózynski et al (2016) or Rød and van der Meer (2009). All these studies focus on visibility analysis and skyline protection with respect towards specific buildings (structures) or panoramas which usually require data on regional scale.…”

A method for the aggregation of spatial data in the study of urban structure on the example of trends in the localisation of tall buildings in Wrocław

“…An increasing amount of research is being conducted with regard to city landscape analysis, the localising of tall buildings and determining strategic views in the city, which should be subject to special protection. The usefulness of this data is very high and the detail of its processing varies depending upon analytical needs (Czyńska, 2015(Czyńska, : 1359(Czyńska, -1366Rubinowicz, Czyńska, 2015: 1395-1402.…”

Advancing the historical geography of late Ottoman and British Mandate Palestine using GIScience: A review

“…This does not mean that HGIS is declining, but rather implies that the discipline is extending beyond the boundaries of the social sciences and is becoming applicable to a wide range of disciplines (Knowles, 2016). With proven quantitative and qualitative capabilities (Cope & Elwood, 2009; Sui, 2015; Wang, 2006), HGIS enables us to perform various tasks such as interogating cartographic materials (Manzano, Martínez, & San‐Antonio‐Gomez, 2012), analyzing maps and sketches (Pavlovskaya, 2016), detecting land use and landscape changes (Bender, Boehmer, Jens, & Schumacher, 2005; Herold, 2018; San‐Antonio‐Gómez, Velilla, & Manzano‐Agugliaro, 2014), creating deep maps for examining the meaning of places and serving as multimedia conveyors of places and the everyday lives of their inhabitants (Bodenhamer, Corrigan, & Harris, 2015), reconstructing historical landscape and cityscape (whether in 2D or 3D) (de Boer, 2010; Georgoula, Stamnas, Patias, Georgiadis, & Fragkoulidou, 2013; Nakaya et al, 2010; Rubinowicz & Czyńska, 2015), and resolving complex scenarios of past phenomena or catastrophes (Verhagen & Jeneson, 2012; Zohar, 2017). Additionally, it is now possible to inspect the development of narratives using map stories (Mennis, Mason, & Cao, 2013) and creating new forms of past virtual knowledge (Gregory & Healy, 2007; Knowles, 2008).…”
