Aerial archaeology in eastern Slavonia in 2014

Istraživanje je provedeno u razdoblju od lipnja do studenoga 2014. godine, a cilj je bio uvidjeti korisnost zračne arheologije na području istočne Slavonije. Prijašnja saznanja upućivala su na velik potencijal ovog plodnoga ravničarskog kraja s velikim parcelama u primjeni ove arheološke metode. Uz sad već brojne mrežne stranice koje donose vertikalne i satelitske snimke, snimanje kosih snimaka iz zrakoplova omogućilo je ciljano arheološko istraživanje.Aerial archaeological survey in two sessions on June 6 and November 12 captured a series of new sites in eastern Slavonia. Apart from the new sites, known sites were also captured, such as, Klisa, airport (fig. 1) (Radić 2007: 284) and Ivanovac, Kolođvar (fig. 2). Sites were spotted either as soil marks (fig. 2), crop marks (fig. 3) or shadow marks (fig. 4). Imagery from traverse aerial shots was completed with the analysis of vertical aerial imagery from cyclic survey by the State Geodetic Administration (SGA) from ARKOD and Geoportal stations, as well as Google Earth, Bingmaps. The analysis confirmed the presence of several sites located during aerial survey in June and November. A site which has a large number of images from practically all the mentioned sources is Klisa, airport (fig. 1). Most circle-shaped sites appear as individual circles, such as Ivankovo (fig. 5) and Viškovci (fig. 4) and concentric circles in case of Levanjska Varoš (fig. 6). They can also appear as identical circles one next to other, which happens to be the case with Preslatinci, Ugljare (fig. 7) (Dekker 1959) or as a combination of big and smaller circles, for example Vrbica, Drake (fig. 8) or Kešinci, Glomač-Požarike (fig. 9). There are remarkable examples of large oval fortifications such as Markušica, Novoševci (fig. 10). Most of the sites have been surveyed and archaeological material has been found on most of them (pottery and lithic finds, mostly). Preliminary view of the pottery has confirmed that the sites cover almost all archaeological periods, but mostly Neolithic and the Middle Ages
