Abstract
Considering the growing negative environmental impacts all over the world and the deteriorating living standards in Sudan, this paper focuses on the authors' contribution to an agricultural project that aims at participating in solving such problems in the study area. The study area, which is exploited by the local farmers, is located north of Omdurman at the western bank of the River Nile. The main objective of the entire project is to establish an irrigation scheme that provides cheaper, sufficient and constant water supply in order to reduce the irrigation cost and effort and increase productivity, leading to reducing the poverty level and improving the living standards. The contribution of the authors in this project is represented in the provision of the basic topographic information which represents a decisive factor for the design of the proposed irrigation scheme. The data used for getting the topographic information were space technology data such as Real time GPS readings, GPS Navigator readings, and Landsat ETM + image, as well as, digital ground survey data such as readings taken by the Total Station survey instrument at site. Using ERDAS Imagine 8.5, the ETM+ image was processed, interpreted to extract the necessary planimetric information. Using ArcGIS9.3 Geostatistical Analyst, the GPS - and Total Station readings were processed to obtain detailed information about the terrain. The effort made by the authors clearly revealed the important role of space technology to conduct the studies that assist in designing projects that reduce the negative environmental impacts and improving the living standards in the project area. The integration of the GIS facilities with this data represents an excellent addition, because it facilitates the presentation of the output in the form of dynamic maps accompanied by attributes of the different layers, beside the static maps. These layers are very useful for designing the detailed engineering activities required for designing the required irrigation scheme in a later stage.
