The modern techniques of the information systems are considered as one of the most
important tools, that most institutions, bodies and organizations working in the areas of
planning and future development are seeking to use as effective analytical
and technical
tools for collecting and analyzing the vast amount of spatial and descriptive information
and the data of the human and natural phenomena, for both planners or decision-makers, at
the various stages of the planning process to cope with the urgent urban problems in
addition to supporting the completion of development plans in record time and high
quality, and reduce waste in energies and resources.
In this context, the research displays the advanced analytical techniques and tool, and
their role in whole planning processes, and identifies the methods of application of GIS
systems as the most efficient and widely used system in the fields of urban planning and
land use, and in developmental decisions support. Also, the research presents a practical
model for the distribution of tasks within the departments and institutions involved in the
planning, to introduce the information systems in their work, and highlights the most
important obstacles that may face the use of those systems.
The study comes up with a number of conclusions and recommendations for the
potential application of advanced techniques and avoiding obstacles, which directly
contribute to raising the efficiency and effectiveness of planning processes, and
improving the planning process management.
To determine the prime potential locations of the hydrocarbon structural traps in
Al-Qaryatein region, which can help in the hydrocarbon exploration processes and reducing a lot of time and fieldwork efforts, lineaments and circular features were i
dentified in the study area by processing and analysing Satellite data using several Remote Sensing techniques and Geographic Information Systems. The priority locations of subsurface structures were distinguished using several special criteria; these criteria are related to the density of the lineaments and their directions within the circular features of the study area. The priority locations of subsurface structures were evaluated by the integration of remote sensing and non-seismic geophysical data which were processed and interpreted by using their own techniques, to determine the prime potential locations of the hydrocarbon structural traps which reached three locations in the study area. The integration between geophysical data and remote sensing techniques increased the trust in the results of this study.

The eco-tourism is an important element in the economic and social development at
the both local and international levels. It represent an essential economic resource for the
governmental sector, so this research particularly important because it i
s looking for the
possibility of using GIS techniques in the protected areas management. The objective of
this study is to verify the GIS importance in creating data-base which is significant for
Naby Matta protected area managers; this data-base is basically helping in the development
of the ecotourism. The results of research confirmed the importance of geographic
information systems in designing of database and the various maps and its role in
determining the steps tourism development such as determining the places of assimilation
and classify it according of the visitors density, select the better tracks for pedestrians, the
appointment of entry points and restaurants, observation points, in addition to the
investment potential of geographic information systems in spatial analysis such as
proximity and distance analysis of particular point from another point, or search for a
particular tourist attraction and find it such as searching for the best spots to enjoy the
picturesque scenery away from sensitive environmental housing thus saving time and
effort and speed in the service of visitors.
The overlay functions in Geographic Information Systems (GIS) are considered as one of the basic functions of these systems, and often, a variety of data stored in layers may be integrated together to generate new layers that contain useful informati
on for decision-makers. All geographic objects are stored in layers and usually rely on crisp set theory, whether, stored in a vector or raster format. In many cases, boundaries of classes or objects are not clearly defined, or when we perform classification of features into classes, the geographic objects located in the boundaries of classes could be classified into the wrong class. This research aims to develop overlay functions methodology based on fuzzy logic, reclassify the objects into fuzzy classes, and study the usability of this method to integrate data of specific phenomenon to help make optimal decisions. To implement and examine this idea, a set of Fuzzy Membership Functions was developed using the Python programming language embedded within the ArcGIS environment. Through this Fuzzy Membership Functions, the user can generate fuzzy sets and combine with each other according to one of fuzzy operations, and thus the generation of fuzzy sets allows supporting the right and reliable decision. To test the proposed fuzzy model capabilities, it has been applied in Tartous governorate to select suitable tourist facility sites in accordance with groups of factors. In summary, data integration using proposed fuzzy overlay functions can improve the reliability of data representation and thus the reliability of make the best decisions.
