Topic & Abstract: Cartographic Representation of Aspect of Desertification For Wasit Governorate
Using Modern Geographic Techniques
The thesis dealt with ... (the efficiency of modern geographic technologies in using statistical methods and mapping, analyzing satellite visuals with different dates, using methods and methods of processing them and preparing them for extracting information and reaching the extent of the available possibilities to reveal the phenomenon of desertification and its risks in terms of accuracy in its drawing, and its ability to store, process and display. And the retrieval and output of geographical information, which allowed the use of these techniques in order to design thematic maps (desertification maps) of the study area to form a nucleus and an applied study that facilitates the decision-makers in finding appropriate solutions to environmental problems)
The thesis aims to show the spatial relationships between the natural and human geographical characteristics and their impact by shaping the phenomenon of desertification in Wasit Governorate, as well as employing modern geographic techniques in detecting the manifestations of desertification and monitoring its changes in Wasit Governorate through the use of spectral indicators (Indices), in addition to identifying the methods of cartographic representation. The phenomenon of desertification in the study area, through the application of geographic information systems (GIS) and remote sensing (RS) in the design and production of digital desertification maps and the representation of data for the study area, so that it can be updated continuously in the event that recent information is available for the study area, whether it is Spatial or descriptive information
The thesis concluded a set of results, the most important of which are .... Desertification map is one of the most important types of objective maps that overlap a group of natural and human factors in its production, and each has a suitable method, means and method in its representation, in addition to the possibility of modern geographic techniques in representing desertification maps and their effective role in Modeling and analyzing it with high accuracy - in addition to the integration between the programs of geographic technologies and the diversity of digital processing methods, which gave great flexibility in analyzing and processing satellite images and calculating digital indicators and evidence, and finally, the study demonstrated the use of spectral indicators of desertification aspects that have a high and accurate ability to identify and monitor desertification in the study area
The thesis recommended ... (the use of modern technology for geographic information systems and remote sensing in the study of desertification maps due to their success in providing a large amount of accurate and fast information on representing the manifestations of desertification, determining their risk levels and revealing their changes, so the geographical studies, especially cartography, should be directed towards modern geographic technologies. In producing and designing maps, instead of traditional methods, to ensure accurate analysis, speed, and shortening of time and effort, as well as developing digital indicators and evidence for monitoring and detecting environmental problems in dry, semi-arid, and even semi-humid areas by conducting specialized studies and experiments in applying these evidence. On the interpretation of a specific milestone only
