Partial results of the project entitled "Laser Scanning and Aerial Photographing of Slovenia 2011" are presented, and the quality control procedure is described. The focus is on the quality assurance of the geo-referencing used for water resource management. Important issues with an impact on the quality of data are addressed and evaluated. The quality of direct geo-referencing was investigated, and some experiences gained in the quality control of the project results are presented. The quality of the transformation of data into the national horizontal and height reference systems is also discussed. Some recommendations for the quality improvement of airborne laser-scanning data are given. This will be possible with the realisation of the new national height reference system and with the creation of the new geoid modelV prispevku je obravnavana problematika zagotavljanja kakovosti podatkov aerolaserskega skeniranja. Predstavljeni so delni rezultati projekta, imenovanega "Lasersko skeniranje in aerofotografiranje Slovenije 2011". Opisani so postopki nadzora kakovosti rezultatov s poudarkom na georeferenciranju, ki bi ustrezalo merilom za njihovo uporabo pri upravljanju voda. Izpostavljeni so dejavniki, ki vplivajo na kakovost podatkov. Dosežena kakovost neposrednega georeferenciranja je ocenjena na podlagi izkušenj, pridobljenih pri nadzoru kakovosti rezultatov projekta. Obravnavana je tudi kakovost transformacij v državni ravninski in višinski referenčni sistem. Podana so priporočila za naknadno izboljšanje kakovosti podatkov, ki bo mogoče z vzpostavitvijo novega državnega višinskega referenčnega sistema in novega modela geoidaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza geodetov Slovenije
