ABSTRACT
Is here presented a methodology of investigation for terri-
torial studies in unknown and almost impenetrable areas of East
Kalimantan
This
photos and
photos, at
land-forms
- Timur (Indonesia).
methodology, based on the photointerpretation of aerial
on few field-checks, permits to carry out from the
the beginning, 3 physiographic maps: hidrologic map,
map and land-use map.
The first one shows the foundamental topographic elements
like main pecks, one road, villages and the complete drainage
patterns.
The second map is characterized by slope-cathegories (4 clas
ses: 0-347,
pending on
1-84, 8-152, over 15%) and by geomorphologic forms de-
the lithology and geologic structures.
The third map is an example of a type of land-use based
mainly on the photointerpretation.
It was possible to recognize 6 classes (Primary forest, Se-
condary forest, Swamp forest, Swamp grassland, Cultivations).
The few field-checks, all the possible ones, permitted the
review of the photointerpretation; to collect some soil informa-
tion; to add some elements for drawing at least two topographic
sections.
Finally, overlapping all these data, we obtained in a short
time a satisfactory land-units map (5 units, each one characteri-
zed by a slope-clas, a land-form and a type of land-use), which
represents
a land-suitability map for human settlements (the aim
of the work).
