Abstract Study sites in Cambridgeshire have been used to assess the relative merits of Landsat Thematic Mapper (TM) data, airborne TM data and conventional panchromatic aerial photographs, for surveying the ecology and land uses of lowland Britain, with particular attention to grasslands. Techniques of computer enhancement, classification and measurement are compared with those involving visual interpretation and manual collation of map information and land-use statistics. Comparisons include measurements of the accuracy and assessments of general accessibility, ease of use, efficiency and effectiveness of the various techniques.
