Remote sensing and Gis were used in studying the relations among natural factors represented by topography and spatial analysis for vegetation land cover in Agricultural land use. This paper mentioned the followings: 1.   Gis applications in topographic analysis of ( SRTM) Digital Elevation Model of the study area . 2.   Remote sensing applications in mapping vegetation land cover and derivation of Agricultural field crops from Landsat scene. 3.   modifying and changing field crops and slope from Raster data to Vector data. 4.   Overlying remote sensing unsupervised classification results and Gis to reveal the relations between slope and the spatial distribution of crops. 5.   Preparing an accuracy classification report from error matrix and required statistical analysis to find significant correlation between slope levels and spatial distribution of crops. SRTM-DEM covering the study area was used as a main source of data for extracting surface slope analysis results by using spatial analyst in ArcGis 9.3 . Landsat 7 Satellite scene was processed in Erdas imagine 9.1 for digital image processing . Unsupervised classification was conducted in extracting the field crops vegetation . Crops layer overlaid on slope to show the relations and the effects of slope levels on the spatial distribution and density of crops in the study area after intersection of both layers. Results showed that (Coefficient of Association ) factor was (- 0.53) correlation factor was (- 0.93) at significant level of 95%.   -  -    –    –    –  –     :                             ) RS&GIS (.                           .      :              ) Dem (            .                 .        )(         ) R2V .(  ) Overlay (               ) slope (   .               .     ) DEMSRTM (       ) (SRTM                      ) ArcGIS V.9.3 (    Spatial Analysis Extension) (         ) Landsat7 (   ) Erdas 9.1 (         ) Unsupervised Classification (         ) Overlay (  ) Slope (    ) Agriculture Crops (                    .              )   (        ) Slope (     -  -
