This paper carried out an over view of the projects of remote sensing application in animal disease surveillance to re-establish the fact that; remote sensing and GIS with its real-time and repetitive ability is operational in animal disease control, forecasting and surveillance with multi-sensor Satellites in the outer space.
he average refractivity gradient and the average effective earth radius (k – factor) estimated for Accra during the period under investigation were found to be -44.1405 N-units/km and 1.39 respectively suggesting that the propagation in this geographical location is mostly super – refractive. The highest and lowest mean values of FSV were found during the dry and rainy seasons in the months of January and June with 3.0998 dB and 0.0158 dB respectively.
The idea based on AURELHY method (Analysis Using Relief for Hydrometeology) which consists of treating or processing the local topography by means of a linear regression, followed by analysis viakriging residuals of the linear model for this cartographic approach.
