An evaluation of the utility of ERTS-1 data for mapping and developing natural resources of Iran

The author has identified the following significant results. Results are reported in structural mapping leading to tectonic interpretation; in surficial deposits mapping; in analysis of salt diapirism in southwest Iran; in updating and correcting existing hydrological maps; in monitoring fluctuations of water in some intermittent lakes; in the delineation of wetland areas and the study of fluvial suspended load of the head of the Persian Gulf in relation to the fishing industry; in exercises in soil mapping; in range and agricultural surveys and inventory using multistage sampling methods, and in the computer analysis of ERTS-1 digital tapes for urban land use. The completion of a 1:1,000,000 false color photomosaic of Iran is also discussed.

NASA plans for future earth resources missions

Development activities underway to improve LANDSAT sensors and observing systems are reported. Data cover high resolution imagery of surface temperatures for improving crop and other vegetation and soil classifications, and heat capacity mapping for recording surface temperatures at hours of maximum and minimum heating. Automatic identification and classification methods designed to extract information such as crop and forage acreages, amounts of water run-off, and types of land use directly from the satellite observations were also studied. A number of applications verification tests were conducted, particularly in the areas of crop and land use inventory and water run-off prediction, to demonstrate the direct transfer of space acquired information to end users.
