| 520 | _aIn the present study a suitable methodology is developed for estimating crop area by integrating remote sensing and GIS based on land survey approach. Area frame surveys are common approaches to gather land cover data. In contrast to mapping approaches, area frame sampling is a statistical method. Based On the visual observation of sample geo-referenced points, area estimates are computed and used as a valid generalization without studying the entire area under investigation. The approach has also the important advantage of not involving/disturbing the land owners and the farmers. The survey concerning the estimation of yield for the major crop will be carried Ollt by cutting small samples in the field. The sample covers the whole Nile valley and the delta, the observed area is about 35000 km' and the distance from South to North is about 1000 km. Digital topographic maps 1:5000 and SPOT5 satellite Images was used, 2,5m resolution, Ortha-rectified (DTM). The survey used the WGS84,Universal Transverse Mercator 36 N, which parameter are given hereafter. | ||
