APPLICATION OF ORBITAL REMOTE SENSING TECHNIQUES IN STUDYING THE WATER QUALITY IN LAGOA DA CONCEICAO, SANTA CATARINA ISLAND - BRAZIL

摘要

By utilizing environmental data (physical, chemical and biological ones) sampled in the years of 1988/89 in the Lagoa da Conceicao as well as the same period TM Landsat 5 satellite images statistical correlations were established. Owned to the non-coincidence between the sampling days and the satellite passage mean punctual values and the satellite passing day weather conditions/similar values were used. Among all the selected environmental data, a water quality indicating bacteriological parametar was used. The results suggest that a set of more studies concerning to that variable should be carried out.
