The traditional method for estimating the condition of plant vegetation, demands a performance of very labour-intensive biometrical analyses. A new approach of estimating the condition of plant vegetation can be remote estimation based on indicators e.g. NDVI. Today, we have the possibility of obtaining mis information by using spectral cameras. This allows the possibility of estimating large areas. The obtained data in the form of photographs, are converted by using geographical information systems(GIS) to the maps e.g. infection of plants, the condition of the vegetation (Kozyra and Pudetko 2006, Bravo et al. 2003). Such methods, are gaining wider use in scientific research as well as in agricultural practice (Kozyra and Pudelko 2006, West et al., 2003 Scotford and Miller 2004). The aim of this research was the estimation into the condition of overwintering winter cereals from aerial low-altitude photography.
