Remote sensing for terrain analysis of linear infrastructure projects

Abstract

This paper examines recent developments in remote sensing applied to civil engineering projects, particularly those involving terrain analysis of linear infrastructure features. Applications using high-resolution satellite data (e.g. IKONOS and Quickbird), laser altimetry and digital elevation models (DEMs) are discussed. Guidelines are given for the stages of a project in which different remote sensing techniques could be employed. The case is also made for greater use of archive remote sensing datasets, which can be a valuable source of information about landscape dynamics.

Improving digital tools for Quaternary field survey: a case study of the Rodoretto Valley (NW Italy)

“…The production of a geological map integrates directly collected field survey data with aerial photography interpretation and/or remote sensing analysis (Compton 1985;Groshong 1999;Gupta 2003;Manning 2007;Walsh et al 1998). GIS are used to overlay maps and other forms of information for simultaneous digital viewing (Gao 2008;Litwin and Andreychouk 2008;Siart et al 2009).…”

Integração de dados do quickbird e atributos do terreno no mapeamento digital de solos por redes neurais artificiais

“…Por sua vez, dados de sensores remotos de alta resolução espacial estão se tornando cada vez mais populares devido ao custo acessível, além de algumas outras vantagens, notadamente o elevado nível de detalhe espacial e as propriedades multiespectrais. Particularmente, os dados do satélite Quickbird, com resolução espacial de 0,6-2,4 m, podem ser uma alternativa às fotografias aéreas convencionais e servir como base para o mapeamento em escalas maiores que 1:25.000 (Manning, 2007).…”

Combining digital elevation data (SRTM/ASTER), high resolution satellite imagery (Quickbird) and GIS for geomorphological mapping: A multi-component case study on Mediterranean karst in Central Crete

“…Particularly the precision of satellite data like Quickbird with a ground sample distance of 0.6 m ( Fig. 1) can compete with that of aerial photography and allows base-mapping at scales between 1:25 000 and 1:2500 (Manning, 2007). DEMs and satellite imagery have been applied to detecting geomorphologic units and various relief features like glacial or aeolian landforms or for assessing the correlation of landforms and land cover (Novak and Soulakellis, 2000;Carré and Girard, 2002;Bolch et al, 2005;Bolten and Bubenzer, 2006;Demirkesen, 2008;Waldhoff et al, 2008).…”
