Redistribution of the energy production to the private houses is an alternative of large power stations at least in a partial manner. Especially, the utilization of solar energy represents a real possibility to exploit the natural resources in a sustainable way. In this study we attempted to survey the roofs of the buildings with an automatic method as the potential surfaces of placing solar panels. A LiDAR survey was carried out with 12 points/m2 density as the most up-to-date method of surveys and automatic data collection techniques. Our primary goal was to extract the buildings with special regard to the roofs in a 1 km2 study area, in Debrecen. The 3D point cloud generated by the LiDAR was processed with MicroStation TerraScan software, using semi-automatic algorithms. Slopes, aspects and annual solar radiation income of roof planes were determined in ArcGIS10 environment from the digital surface model. Results showed that, generally, the outcome can be regarded as a roof cadaster of the buildings with correct geometry. Calculated solar radiation values revealed those roof planes where the investment for photovoltaic solar panels can be feasible.

To perform such an evaluation, we investigated an area of approximately 5500 m2 on the Great Hungarian Plane. Altogether 578 points were surveyed with a high-precise LASER beam based total station. The techniques used for the interpolation of point height data include: inverse distance weighting (IDW) and ordinary kriging, prepared in HydroDesktop 1.4 and ESRI ArcGIS 9.3, as well. Our goal was to examine and compare the different types of interpolation surfaces and to rank the gained surfaces based on their accuracy. The reference was an airborn LiDAR surface. Our examination shows that in such cases (e.g. kriging) interpolation can be different in the two softwares, and there is only an inconsiderable difference between IDW techniques in both software, based on RMS error. In addition, the results represent that the data are significantly scattered at the lower value of evaluation in every case of interpolation methods. The reason for this phenomenon could be explained by the presence of wooded vegetation.
