IMG_0810Earth Observation (EO) systems and the advances in remote sensing technology increase the opportunities for monitoring the thermal behaviour of cities. Several parameters related to the urban climate can be quantified from EO data products, providing valuable support for advanced urban studies and urban climate modelling. In this study, remote sensing techniques are applied to derive quantitative information necessary to identify the Local Climate Zones (LCZ). Parameters like the pervious and impervious surface fraction, the surface albedo, the building density, the mean building/tree height and the sky view factor are quantified for a study area in Crete, Greece. The EO products are then used under a methodological framework to map possible zones with homogeneous thermal characteristics, considered as LCZ.

IMG_0716Individual EO products, as well as the LCZ classification itself, is useful to urban climate modeling and studies to assist planning and decision making.

Future research includes the investigation of more urban parameters extraction with EO data, with ultimate goal is to develop a methodology, adapted to the Sentinels.

The study has been presented at the last JURSE congress in Lausanne, by Zina Mitraka, Nektarios Chrysoulakis, Fabio Del Frate and Jean-Philippe Gastellu-Etchegorry.
