Abstract: The article presents a database designed to compare the results of extensive and intensive field surveys on Slovenian motorways, with the aim of evaluating the effectiveness of the survey methodology. The database was created through a spatial comparison of the results of extensive and intensive surveys on Slovenian motorways. It contains data from 258 intensively surveyed locations, of which 19 do not overlap with areas covered by extensive survey, while 232 do overlap and are therefore suitable for comparison between the two phases or survey strategies. Individual locations are presented in tables containing data on the number of finds recorded in each period; the size of extensively and intensively surveyed areas; the ratios between the sizes of extensively and intensively surveyed areas and surface and subsurface surveyed areas; the densities of individual types of material identified through surface and subsurface surveys; the ratios between the densities of individual types of material recorded in the extensive and intensive phases; and the regionalisation of locations. In addition, the database includes text with supporting analysis comparing the results of the extensive and intensive phases of the surveys, which was not included in the related original scientific paper. The database is stored in the Repository of the University of Ljubljana. It allows reuse by verifying the presented analysis results or further analysing the given dataset. Izvleček: Prispevek predstavlja podatkovno zbirko, namenjeno primerjavi med rezultati ekstenzivnega in intenzivnega terenskega pregleda na avtocestah Slovenije, katere cilj je bil ovrednotenje učinkovitosti metodologije pregledov. Zbirka podatkov je bila ustvarjena s prostorsko primerjavo rezultatov ekstenzivnih in intenzivnih pregledov na avtocestah Slovenije. Skupno obsega podatke o 258 intenzivno pregledanih lokacijah, med katerimi je 19 takih, ki se ne prekrivajo z območji ekstenzivnega pregleda, in 232 takih, ki se s temi območji prekrivajo in so tako primerne za primerjavo med obema fazama oz. strategijama pregleda. Posamezne lokacije so predstavljene v tabelah, ki vsebujejo podatke o številu odkritih najdb posameznega obdobja: o velikosti ekstenzivno in intenzivno pregledanih površin, o razmerjih med velikostjo ekstenzivno in intenzivno ter površinsko in podpovršinsko pregledanih površin, o gostotah posameznih vrst gradiva, odkritih s površinskim in podpovršinskim pregledom, o razmerjih med gostoto posameznih vrst gradiva, odkritih v ekstenzivni in intenzivni fazi, ter o regionalizaciji lokacij. Poleg tega podatkovna zbirka vsebuje besedilo s podporno analizo primerjave rezultatov ekstenzivne in intenzivne faze pregledov, ki ni bila vključena v povezani izvirni znanstveni članek. Podatkovna zbirka je shranjena v Repozitoriju Univerze v Ljubljani ter omogoča ponovno rabo v obliki preverjanja predstavljenih rezultatov analize ali izvajanja nadaljnjih analiz na predstavljenem nizu podatkov.
