It is known that the relief forms are considered as eco- 
nomically profitable when they are being used for human acti 
vities. As this is generally not the case in the Amazon Re- 
gion, the RADAM geomorphologic maps try to point out the  a- 
reas potencially capable to become valuable when especific - 
projects are implanted. 
Therefore: 
- Flat areas (with a weak rate of erosion) have been separa- 
ted from dissecated areas (with a strong rate of erosion). 
- In flattened areas, it was investigated whether the geologic 
structure was affected and whether mineral resources could 
be there encoutered. or not, 
- Fluvial plains were defined as to their nature so that those 
always flooded or occasionally overflown, could be detatched 
From firm ground. 
- In flat areas the nature of flattening was investigated ai- 
ming to recognize minerals resistant to erosion and where 
they might be acumulated. 
- Topographic features and flood conditions have been delinea 
ted for roads design effect. 
The team of Geomorphology, in a tentative to exchange infor 
mation and results of their investigations, promoted an in- 
tegration with the Geomorphology Committee of the American 
States Organization in charge of preparing the Geomorpholo- 
gic Map of South America. 
With the same objetive, this team contacted the Centre 
de Geographie Appliquée de L'Université de Strasbourg and 
stablished a joint venture working program, since that Uni- 
versity maintains an experimental laboratory for the inter- 
pretation of RADAR images.
