| Abstract: | The paper describes work undertaken in North Wales in 1967 and 1968 in which panchromatic and colour air photographs were used in the mapping of vegetation and in the study of other ground surface features. The problems of relating a priori classification schemes to the categories distinguished by air photo-interpretation are discussed and the case stated for developing classifications which enable more benefit to be derived from the advantages of air photo-ecology. |
