The final products are highly dependent on the choice of values for various parameters in flight planning, the type of sensors, and the processing of the data. In this paper ground control points (GCPs) were first measured using the Global Navigation Satellite System (GNSS) Real-Time Kinematic (RTK) method, and then due to the low height accuracy of the GNSS RTK method all points were measured using a detailed leveling method. This study aims to provide a basic assessment of quality, including four main aspects: (1) the difference between an RGB sensor and a five-band multispectral sensor on accuracy and the amount of data, (2) the impact of the number of GCPs on the accuracy of the final products, (3) the impact of different altitudes and cross flight strips, and (4) the accuracy analysis of multi-altitude models. The results suggest that the type of sensor, flight configuration, and GCP setup strongly affect the quality and quantity of the final product data while creating a multialtitude model does not result in the expected quality of data. With its unique combination of sensors and parameters, the results and recommendations presented in this paper can assist professionals and researchers in their future work</dc:description><dc:description xml:lang="sl">V zadnjih nekaj letih daljinsko vodeni letalniki (angl. unmanned aerial vehicles) postajajo vse pomembnejše orodje za hitro zbiranje visokoločljivostnih slik Zemljine površine (prostorsko in spektralno). Končni izdelki so zelo odvisni od izbire vrednosti različnih parametrov pri načrtovanju leta, vrste senzorjev in obdelave podatkov. V članku so najprej izmerjene oslonilne točke (angl. ground control points) z uporabo metode GNSS RTK, nato pa so bile vse točke zaradi nizke višinske točnosti metode GNSS RTK izmerjene s podrobno nivelacijsko metodo. Cilj študije je zagotoviti osnovno oceno kakovosti, vključno s štirimi glavnimi vidiki: (1) razliko med RGB-senzorjem in petpasovnim multispektralnim senzorjem glede na točnost in količino podatkov, (2) vplivom GCPs na točnost končnih izdelkov, (3) vplivom različnih višin in prečni snemalni pas ter (4) analizo točnosti modelov z več višinami. Rezultati kažejo, da vrsta senzorja, konfiguracija leta in postavitev kontrolnih točk močno vplivajo na kakovost in količino končnih podatkov izdelkov, medtem ko ustvarjanje modela z več višinami ne prinese pričakovane kakovosti podatkov. Z edinstveno kombinacijo senzorjev in parametrov lahko v članku predstavljeni rezultati in priporočila pomagajo strokovnjakom in raziskovalcem pri prihodnjem delu</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-FT8OUEF3"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-FT8OUEF3" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-FT8OUEF3/a704e92f-8931-4850-89be-689feb8ff02c/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Zveza geodetov Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-FT8OUEF3/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-FT8OUEF3" /></ore:Aggregation></rdf:RDF>
