Synopsis (short abstract) Aerial photographs have been used for several decades in the study of the earth's surface. Scientists extract from the vast range of information in each set of air photos, such data as is relevant to their particular field of study. They must learn how to handle the photographs and also know how different objects on the surface of the earth are represented in a photographic image. The study of the image of those photographed objects and the deduction of their significance is usually called

    The concept of aerial surveys for estimating the fishery resources and various related parameters is new to a country like India, but the UNDP/FAO Pelagic Fishery Project, Cochin had conducted three such surveys in 1972, 1973 and 1974, mainly for estimating the pelagic fishery potential in the Project area extending from Tuticorin in the south to Ratnagiri in the north along the south-east and south-west coasts of India. The present survey, the fourth in the series, has been planned by Dr. G.P. Bazigos (FAO Consultant) and conducted under his leadership. The objective of this survey was primarily for obtaining a synoptic picture of the fishing effort distribution and localization of the inshore fishing industry in the Project area with a view to correlating it with the distribution of the resources located by the acoustic surveys of the Project. The survey was conducted using an 8-seater Twin-Beech aircraft chartered from M/s Goldensun Aviation, Bombay, from 27 to 30 September 1978 . This report includes accounts of the structure of the fisheries of the Project area such as information on non-mechanized and mechanized fishing crafts, gears, resources, fishing seasons and grounds and the presentation, analysis and critical analysis of the data collected during the survey.

    Soil survey interpretation and its use 1967
    Also available in:

    This soils bulletin brings together some of the methods which have been developed and tested in countries that have active programs of making and using soil surveys, and a summary of some of the principles of soil survey interpretation. It is mainly addressed for the soil scientist who is making and interpreting a soil survey, or who is re-interpreting a soil survey already completed. Methods are suggested, with examples, for comparative ratings of soils, capability grouping of soils for the com mon crops, estimating yields of crops on different kinds of soil under defined sets of other growth factors, groupings of soils for range and for woodland management, and use of soil maps and reports in engineering work that involves soils as foundations or as construction material. There are also brief discussions of soil maps for planning, use of soil maps in appraisal of land, and the preparation and use of general soil maps.
