233 ASSESSMENT OF VOLUME CHARACTERISTICS OF TROPICAL RAIN FORESTS ON LARGE SCALE AERIAL PHOTOGRAPHS P.J.D. Versteegh*) ABSTRACT The usefulness of large scale aerial photography of a tract of tropical rain forest in Surinam was investigated, by the ITC Forestry Department. Panchromatic BW, colour, and infrared colour photos of 70 mm size and 1 : 5,000 scale were available for initial tests on the possibilities of special recognition, crown counts, and stratified crown counts. The use of colour filmtypes offered little better possibilities than pan chromatic BW. More extensive investigations were carried out after a panchromatic BW, narrow angle photo coverage of 1 : 5,000 scale and 23 cm size was acquired. The results of the tests indicate that crown counts and stratified crown counts offer possibilities for assessment of the timber potential of the forest. RÉSUMÉ Le département de sylviculture de l’ITC a recherché l'utilité de la photo graphie à grande échelle pour l’étude d’une étendue forestière en zone tro picale humide de Surinam. Pour les essais initiaux les documents dispo nibles étaient des photographies 70 mm, à l’échelle du 1/5.000, panchroma tiques en noir et blanc, en couleur et en couleurs-infrarouges. Ces essais initiaux partaient sur les possibilités de reconnaissance des espèces, sur le comptage complet des couronnes et des différentes couches de l’utilisation des émulsions en couleurs donnèrent des résultats très légèrement meilleurs à celle des émulsions en noir et blanc. *) Senior lecturer in the Forestry Dept.
