Complementary use of non-destructive methods, including remote-sensing and field walking surveys may provide a clearer and more reliable look at archaeological remains visible on the surface. One of the traditional methods is fieldwalking surveys, which is usually carried out extensively and intensively. An extensive field survey is very helpful in locating new sites, estimating its size, quantity and quality of finds, its chronology, and state of preservation. An intensive field survey is a more detailed method focused on the spatial dispersion of finds (see metal detectors survey).
The vicinity of the legionary fortress has been investigated by extensive field surveying by the Bulgarian-German Expedition (Conrad, Stančev 2002). The vicus at Ostrite Mogili has been investigated in 1977 and in 2000 (Sarnowski 1979; Tomas 2006).
The vicinity of Novae, including some parts of the canabae were surveyed again in 2012 and 2013. The first attempt was focused on the verification of its size, which was not an easy task due to the presence of the summer houses in the area. The GPS hand-held devices were helpful in marking the border points of the site. More detailed investigations were carried out in the area of the annex, particularly in its central and southern part.
The settlement at Ostrite Mogili was investigated in 2013 and 2014. The aim of the prospection was to establish its accurate size and its easternmost borders and the accurate map of the site, as well as to investigate more intensively the eastern part of the site, where the archaeological materials are densely spread on the surface.
