AERIAL SURVEY METHODS FOR FORESTRY
AND FOREST INDUSTRY PRE-INVESTMENT SURVEYS
IN DEVELOPING COUNTRIES
by David A. Francis
Forest Economics Branch, Forestry and Forest Products Division, F A.O., Rome
Abstract The requirements of forestry and forest industry pre-investment surveys are
stated, the particular needs of developing countries are stressed, and the methods of meeting
these requirements are discussed : Necessity for sound planning of economic development.
Preliminary investigations essential to determine practicability of development projects and
scale of investment required. Attention is paid to recent advances in aerial survey methods,
both equipment and techniques. Mention is made in particular of the use of visual aerial
surveys and helicopter operations for field sampling in remote areas. Specific countries and
projects are referred to and selected cases mentioned which stress the limitations, as well as
the advantages, of present aerial survey methods. Economy of sampling, speed, ease of opera
tion and cost of pre-investment forestry and forest industries surveys are covered. The fact
that aerial survey techniques are not restricted to the determination of raw material supplies
i.e. an assessment of the forest resources of an area, is brought out. Aerial photographs are
also used for studies of related factors in project feasibility surveys : power and water supplies,
communications, selection of sites for industry plants etc.
Résumé L’éxposé présente les besoins en matière d’enquêtes préalables aux investissements
dans le domaine des forêts et des industries forestières; il souligne les besoins particuliers des
pays en voie de développement et étudie les méthodes aptes à satisfaire ces besoins. Le déve
loppement économique doit être rattionnellement planifié et des recherches préliminaires
sont essentielles pour déterminer dans quelle mesure les plans de développement sont réali
sables ainsi que l’importance des investissements nécessaires. Les progrès récents des méthodes
de reconnaissance aérienne, tant en matière d’équipement que de techniques, sont considérés;
les reconnaissances visuelles sont notamment mentionnées, ainsi que l’emploi d’hélicoptères
pour l’échantillonnage sur le terrain dans des zones éloignées. Des pays et des projets parti
culiers sont cités; certains cas sont signalés, soulignant les limitations, ainsi bien que les
avantages, des méthodes actuelles de reconnaissance aérienne. L’économie de l’échantillon
nage, la rapidité, la facilité de réalisation, et le coût des enquêtes préalables aux investisse
ments pour les forêts et les industries forestières sont traités. Le fait que les techniques de
reconnaissance aérienne ne servent pas exclusivement à déterminer les ressources en matières
premières, c’est à dire à évaluer les ressources forestières d’une région, est mis en évidence.
Les photographies aérienne servent aussi à étudier des facteurs connexes dans des enquêtes
sur les possibilités de réaliser un projet: ressources énergétiques et hydrographiques, commu
nications, choix des sites pour des industries forestières, etc.
Zusammenfassung Die Anforderungen an eine forst - und holzwirtschaftliche Inventur
für Investitionsplanung werden aufgezählt, die besonderen Bedürfnisse der Entwicklungs
länder betont und die Methoden, ihnen gerecht zu werden, diskutiert: die Notwendigkeit
fundierter Planung der Wirtschaftsentwicklung. Vorläufige Untersuchungen sind wichtig,
um die praktische Durchführbarkeit von Entwicklungsprojekten und das erforderliche Investi
tionskapital richtig einzuschätzen. Jüngste Fortschritte der Inventurmethoden mit Luft
aufnahmen werden besonders berücksichtigt, Geräte und Aufnahmetechnik dargestellt. In
venturen durch Luftbeobachtung und die Benutzung von Flelikoptern für Bodenprobenahmen
in schwer zugänglichen Gebieten werden erwähnt. Bestimmte Länder und Projekte werden
als Beispiele erwähnt und gewisse Fälle angeführt, die die Vorteile und Grenzen der gegen
wärtigen Inventurmethoden mit Luftaufnahmen deutlich machen. Wirtschaftlichkeit der
Probenahme, Geschwindigkeit, Leichtigkeit der Arbeiten und Kosten werden behandelt.
Es wird deutlich gemacht, dass Inventuren mit Hilfe von Luftaufnahmen nicht auf Einschät
zung der Rohstoffbasis beschränkt sind. Luftaufnahmen werden auch für Erkundung ande
rer wichtiger Fakten herangezogen: Energie- und Wasserversorgung, Transportverhältnisse,
Wahl des Standorts für holzwirtschaftliche Betriebe, usw.
