to locate zones in the sea that are good fishing grounds. A model is being 
developed in which the main parameter is the sea surface temperature 
obtained by means of the thermal imagery of NOAA and SMS satellites. Other 
parameters like catch statistics, salinity, chlorophyll content etc. are 
also taken into account. The system is being planned in such a way that the 
information will go to the fisherman in the shortest possible time. 
Oceanography and Hydrography 
Among the projects developed in this program, the following 
that have been concluded recently can be mentioned: 
e Study of the thermal discontinuity between the Brazil and Falkland 
Currents with the THIR imagery of Nimbus , V (TSENG 77). The knowledge 
of the behavior of this discontinuity is important because it has 
. been verified that it is a good Pargo Roseo fishing ground. 
e A study of the circulation patterns of the Lagoa dos Patos, State 
of Rio Grande do Sul, has been concluded (HERZ 77). Landsat imagery 
and SKYLAB photography were used in this work. 
Actual and Potential Land Use Mapping 
Recently a project to classify the urban land use of Sao 
José dos Campos, based on Landsat imagery, has been concluded (NIERO 78). 
Presently a project to map the land use of the Paraiba River 
Valley, between the cities of Rio de Janeiro and Sao Paulo, is being 
developed. This valley is undergoing a very accelerated industrialization 
which is causing serious distortions in the adequate use of the land 
(COTTR 78) . 
Another project being developed is the evaluation of the 
impact on the land use of a region due to the construction of a secondary 
road.
