Megjegyzések:Energy production and consumption is a key element in future development which is influenced both bythe technical possibilities available and by decision makers. Sustainability issues are closely linked inwith energy policy, given the desire to increase the proportion of renewable energy. According to theHorizon 2020 climate and energy package, European Union (EU) member countries have to reduce theamount of greenhouse gases they emit by 20%, to increase the proportion of renewable energy to 20%and to improve energy efficiency by 20% by 2020. In this study we aim to assess the opportunitiesavailable to exploit solar radiation on roofs with Light Detection And Ranging (LiDAR) and photogrammetrytechniques. The surveyed areawas in Debrecen, the second largest city in Hungary. An aerial LiDARsurvey was conducted with a density of 12 points/m2, over a 7 1.8 km wide band. We extracted thebuilding and roof models of the buildings from the point cloud. Furthermore, we applied a low-costdrone (DJI Phantom with a GoPro camera) in a smaller area of the LiDAR survey and also created a 3Dmodel: buildings and roof planes were identified with multiresolution segmentation of the digital surfacemodels (DSM) and orthophoto coverages. Building heights and building geometry were alsoextracted and validated in field surveys. 50 buildings were chosen for the geodetic survey and the resultsof the accuracy assessment were extrapolated to other buildings; in addition to this, 100 building heightswere measured. We focused primarily on the roofs, as these surfaces offer possible locations for thermaland photovoltaic equipment. We determined the slope and aspect of roof planes and calculated theincoming solar energy according to roof planes before comparing the results of the point cloud processingof LiDAR data and the segmentation of DSMs. Extracted roof geometries showed varying degreesof accuracy: the research proved that LiDAR-based roof-modelling is the best choice in residential areas,but the results of the drone survey did not differ significantly. Generally, both approaches can be applied,because the solar radiation values calculated were similar. The aerial techniques combined with themultiresolution processing demonstrated can provide a valuable tool to estimate potential solar energy.
