The importance of this research lies in establishing an integrated system to support decision making of bituminous road surface maintenance in Lattakia within the environment of Geographic Information Systems, which leads to improve the level of performance and reach better conditions of road safety and comfort. In a former research, the bituminous surface condition data was conducted and filled in the Asphalt Institute Form by which we obtained an overall condition rating that led in turn to the type of maintenance of each studied segment and link them to the digitized maps where every segment appeared in a color reflecting its condition according to the purpose of the map. In this research we depended on the " Project Priority Methodology " to view and query different alternatives to support decision making of which road segments should be maintained first by using five categories each one gives us a weighing value, then we collected the total weighed value for the five categories together, and link that to digitized maps that guaranteed fast and direct reach to various solutions to choose the best, insuring as a result that the traditional way in maintenance which begins with the worst segment is not always the best, and that its time to move towards new pavement maintenance management systems.

Research summary
تتبع أهمية هذا البحث من خلال إنشاء نظام متكامل لدعم اتخاذ القرار المتعلق بصيانة سطوح رصف الطرق البيتومينية في اللاذقية باستخدام نظم المعلومات الجغرافية (GIS). يهدف النظام إلى تحسين الأداء والوصول إلى ظروف أفضل من الراحة والأمان لمستخدمي الطرق. في البحث السابق، تم جمع بيانات حالة سطح الرصف باستخدام طريقة معهد الأسفلت، وتم تصنيف حالة الطرق ونوع الصيانة اللازمة لكل قطاع وربطها بالخرائط الرقمية. في هذا البحث، تم استخدام منهجية تفضيل المشاريع حسب أولويتها لتحديد القطاعات التي تحتاج إلى الصيانة أولاً. تم استخدام خمس فئات لتحديد الأولويات، وتم ربط النتائج بالخرائط الرقمية لضمان الوصول السريع والمباشر للحلول. أكدت النتائج أن الطريقة التقليدية في صيانة الطرق التي تبدأ بالأسوأ ليست بالضرورة هي الأنسب، وأوصت بالانتقال إلى نظم إدارة صيانة الرصف الحديثة.
Critical review
تعتبر هذه الدراسة خطوة هامة نحو تحسين إدارة صيانة الطرق في اللاذقية باستخدام تقنيات حديثة مثل نظم المعلومات الجغرافية ومنهجية تفضيل المشاريع. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، الدراسة تركز بشكل كبير على الجانب التقني دون تقديم تحليل كافٍ للتحديات المالية والإدارية التي قد تواجه تطبيق النظام المقترح. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية والمناخية على أداء النظام المقترح. ثالثاً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت مقارنة مع نظم إدارة صيانة الطرق في مدن أو دول أخرى للاستفادة من تجاربهم. وأخيراً، بينما تم استخدام منهجية تفضيل المشاريع، لم يتم توضيح كيفية تحديد الأوزان النسبية للفئات المختلفة بشكل مفصل، مما قد يؤثر على دقة النتائج النهائية.
Questions related to the research
  1. ما هي أهمية استخدام نظم المعلومات الجغرافية (GIS) في صيانة الطرق؟

    تساعد نظم المعلومات الجغرافية في توثيق وتحليل وعرض البيانات المرتبطة بالرصف بطريقة تفاعلية وسهلة، مما يسهل عملية اتخاذ القرار المتعلق بالصيانة ويوفر الوصول السريع والمباشر لمختلف البيانات والحلول.

  2. ما هي الفئات الخمس المستخدمة في منهجية تفضيل المشاريع حسب أولويتها؟

    الفئات الخمس هي: حجم المرور، حالة الطريق، الالتزام المحلي، السلامة، وإجراءات التحكم بالنقل.

  3. لماذا تعتبر الطريقة التقليدية في صيانة الطرق التي تبدأ بالأسوأ ليست بالضرورة الأنسب؟

    لأن البدء بصيانة القطاعات الأسوأ قد لا يكون الأكثر فعالية من حيث التكلفة والفائدة على المدى الطويل. النظام المقترح يهدف إلى تحديد الأولويات بناءً على مجموعة من العوامل لضمان الصيانة الأكثر كفاءة.

  4. ما هي التوصيات الرئيسية التي قدمتها الدراسة؟

    أوصت الدراسة بأن تكون الصيانة في المؤسسات الطرقية عملاً إدارياً متكاملاً وليس مجموعة من المهمات المنفصلة، وأكدت على ضرورة عدم تقييد عقود الصيانة بقيم محددة ولكن حسب الدراسات والمتطلبات الفعلية. كما أوصت بمتابعة وتوسيع الأبحاث في مجال نظم إدارة صيانة الرصف الطرقي.

This research highlights the vital role of Pavement Management Systems integrated with Geographic Information Systems in planning and managing road maintenance in Lattakia, and getting a flexible local system by following a new method in processing a nd viewing information that supports maintenance decision. This study included applying a pilot project for managing pavement maintenance over a group of roads following The General Establishment for Road Communications. Those roads were divided to links and segments then evaluated using the " Asphalt Institute Method ", which gave us a numeric pointer that led in turn to the type of maintenance needed for a particular pavement. In this research, we depended on the Geographic Information Systems to design and build a comprehensive database, that reflected the present condition of the studied roads, and enabled us to store, analyze and document pavement surface condition and link it to the digitized maps of the studied roads. This guaranteed easy and direct access to various kinds of data and solutions as every segment appeared in a different color reflecting its conditions according to the theme of the map. By doing so, we could support the process of taking right maintenance decisions.
3D models of historical sites and monuments are very interesting in archaeology and digital tourism fields. These models help archeologists document historical sites and analyze the relationships between their components. Moreover, 3D models constitu te an attractive factor that encourages visiting sites and presents virtual information about cultural heritage. In this paper, we propose an approach that uses capabilities of CAD (Computer Aided Design) and GIS (Geographic Information System) systems to construct spatial and semantic database for historical sites and modeling them in 3D. Users of the mentioned database can use it to gather information about sites and to navigate across them via the animation capabilities in GIS. The proposed ideas will be applied on the historical site of Ras-SHAMRA in Lattakia. Spatial data concerning the site will be acquired form a topographic plan designed in 2004. These data will then be processed and introduced into GIS environment. ArcGIS software will be used to achieve an Archeological Information System (AIS) for the site and to construct a 3D model of the site and the royal palace.
The Drastic method has been used to assess the potential sensitivity of the Groundwater In Lattakia basin using Arc GIS 9.2 Where the modified Drastic system has been developed by combining the land uses and its divisions with general Drastic model .As a result, final values of Drastic have been modulated into two categories "low and moderate sensitivity" It has been found that the introduction of the human criteriahas increased the potentialof the moderate sensitivity of the Groundwater. As a final result, the general content of the sensitivity map which has been establishedfor Lattakia basin, showed, the domination of low sensitivity category in the north western and the north eastern areas which has big location depths of the Groundwater and high topographic altitudes.In contrast, the moderate sensitivity category dominated in the southern areas of the study region. The latter areas which are characterized by the existence of varied human activities havelocation ofGroundwater levels close to the surface.
The Marketing information systems are considered the backbone of decision making, particularly these needed to run facilities with higher efficiency and effectiveness of marketing process. The study recommends that the served facilities ought to d evelop the organizational structure, in away leaving the routine more over forwarding towards more flexible structures, and decentralization in decision making. As well as getting rid of operation standards, standing in the hand in order to rationalization of the decision made. And getting the valuable, credibility and economic information at suitable time allows to rationalization and directing activities the existing process of marketing the rationalization and directing activities to achieve at higher level, This enforce the facility to be awareness to the importance of providing effective marketing information system, This make it able to govern the process of decision making, reduce the time and effort which is responsible for search from information and analysis it, and enable it be able to assess the prospects for the future, and the face of environmental changes.
The main goal of this study is to produce landslide sensitivity mapusing GIS at Syrian Coast area.At the first stage of the study, 75% of the landslides locations (45 landslide locations) are used as training dataset and the rest was used as (15 la ndslide locations) the validation dataset. Fourteen input data layers were employed as landslide conditioning factors in the landslide sensitivity mapping. These factors are slope degree, aspect, altitude, plan curvature, profile curvature, tangential curvature, surface area ratio (SAR), lithology, land use, distance from faults, distance from rivers, distance from roads, topographic wetness index (TWI) and stream power index (SPI). Using these conditioning factors, landslide sensitivity index was calculated. Subsequently, the result was plotted in ArcGIS and landslide sensitivity map was obtained. The produced sensitivity map is useful for general land-use planning.
