EOS has been providing an enormous quantity of spatial data, and it is predicted that the global satellite data market will expand exponentially. Processing such vast and unique data in an efficient manner is necessary. Google Earth Engine (GEE) is an example of a cloud-based geospatial platform that revolutionized the way users store, process, analyze, and visualize spatial data. This chapter delves into the fundamentals of digital image processing, employing cutting-edge techniques to process, analyze, and visualize remotely sensed data through the use of Google Earth Engine (GEE) and JavaScript API. This chapter presents an in-depth exploration of digital image processing, specifically focusing on remotely sensed data. It highlights advanced techniques and includes two case studies that demonstrate practical applications in preprocessing and detailed analysis of land use and land cover (LULC) changes.

Khartoum is separated by three Niles and linked by eight bridges to Khartoum North and Omdurman. The construction of these bridges disrupted the natural flow of water and sediments which will consequently be reflected on the geomorphological settings of fluvial islands including erosion and sedimentation patterns. The objective of this study is to monitor and assess the development of fluvial islands in Khartoum State up to Sabaloka Gorge using Remote Sensing (RS) and Geographical Information System (GIS) techniques. Landsat Images captured during the period from 1975-2015 with standard false color and standardized 30 m resolution were found useful in understanding the impacts of bridges on disrupting the fluvial cycle. Consequently, the rates, trends of erosions and deposition, and the developmen...

Prior to the conference, debate over food and agricultural biotechnology was focused on three product groups: herbicide tolerant crops, animal drugs (especially BST), and crops engineered with the Bt gene. Although there are a few important exceptions, most products approved for use in the United States fall into one of those three groups. Debate over those products created an alignment of interests where agricultural input suppliers, the food industry, and commodity organizations opposed a coalition of interest groups representing food consumers, environmental and animal protectionists, and small scale farmers. Universities and government were caught in the middle. Only a few products (notably recombinant chymosin, the enzyme used in the production of cheese) escaped. The Rutgers meeting provided an overview of the products that may come on-line from agricultural biotechnology early in the next century. The papers in this conference report describe new food products that will do far more to enhance the dimensions of quality that are important to consumers: taste, purity, and visual appeal. If the food industry can ensure the safety of biotechnology foods (arguably in place now at the Food and Drug Administration (FDA)) and protect the principle of individual consent and control (labels are arguably the answer), these new products will enjoy consumer support, rather than opposition. What is more, new food crops that emphasize disease resistance or that utilize less toxic forms of pest control (such as Bt crops) should garner support from the environmental community.
