يتضمن البحث دراسة جيوديزية لشبكة المثلثات العقارية المحلية في منطقة صلنفة، و اقتراح حل من أجل ربط الشبكة المحلية بالشبكة العقارية العامة في سورية. يعتمد العمل على مقارنة نتائج التحويل ثنائي الأبعاد، بحيث يتم اختيار التحويل الأمثل الذي يتلافى حدوث تداخلات بين المناطق و المخططات العقارية، و يقلل من تشوهات الشبكة بعد تحويلها (انزياح، دوران، مقياس). في البداية تم التطرق إلى تاريخ انشاء الشبكة الجيوديزية في منطقة صلنفة و مراحل تنفيذها، و مشاكلها الهندسية، و ثم إلى طرق التحويل المستخدمة في الربط، و تطبيقها على الشبكة، و اختيار التحويل الأفضل، و تعيين بارمترات التحويل المناسبة. و تم اقتراح حل يعتمد على تقسيم الشبكة إلى ثلاث قطاعات، بحيث يقلل تشوه الشبكة الناتج عن التحويل في كل قطاع. تم اعداد برنامج حاسوبي لتنفيذ التحويل المُقترح و ربط نقاط الشبكة المحلية باستخدام لغة البرمجة C#. و تم التحقق من بارمترات التحويل الناتجة بمقارنة القياسات الخطية المحسوبة من الاحداثيات الناتجة عن التحويل مع القياسات الخطية الموجودة في دفاتر رصد الشبكة، و بإجراء قياسات حقلية لبعض النقاط الموجودة و حساب احداثياتها و مقارنتها مع الاحداثيات المحسوبة عن التحويل.
Search includes the geodetic study local network triangulation real estate in Slenfeh area, and propose a solution for the local network linking public real estate network in Syria based on a comparison of the 2D-Transformation results so as to choose the optimal conversion which avoids the occurrence of interactions between regions and schemes real estate and reduces distortions network after conversion (shift, rotation, scale). At first been touched to date geodesic network set up in Slenfeh region and the stages of execution, and the problems of engineering, and then to the transformation methods used in the link, and apply them to the network, and choose the best conversion, and set parameters optimal transformation, have been proposed solution depends on the network is divided into three segments so that Network least deformation resulting from the transformation in each sector. A computer program that has been prepared for the implementation of the transformation and linking local grid points by using the C # programming language. It has been verified the resultant transformation parameters by comparing linear measurements calculated from coordinates resulting from the transformation with linear measurements in the network observation records, and execution field measurements of some of the points and calculate its coordinates and compare it with the coordinates calculating fromtransformation.

The transformation of coordinates between the global coordinate system yield
ellipsoid WGS84 (World Geodetic System 1984) and the local coordinate system yield
ellipsoid Clark1880 in different regions of Syria, is the essential step in the effectiv
e use of
GNSS (Global Navigation Satellite Systems) surveying techniques in Syria, and the
transformation occurs with 3D transformation between one ellipsoid and another, or 2D
transformation directly between two planar. The transformation must be understood,
analyzed and tested. The research is about the accuracy of the 2D transformation in small
area to give coordinates can be directly used in different surveying and engineering works,
and about studying the common points number and their distribution effect on
transformation accuracy, and conclude that the biggest effect on transformation accuracy is
for the common points distribution.
In this paper, we define tensors and space Riemann spaces and
fixed curvature, and offer a study of some cases associated
with the search topic, the basic function is to study the
relationships that remain valid when the coordinates system
change to another system.
The main objective of this research is to develop an
arithmetic model for transformations between geographic and
State Plane Coordinate within the three types of Conformal
Syrian Conical projection (tangent, secant and Semiconformal),
In order to
enable all Specialists and surveyors to
carry out direct and reverse transformations of horizontal
coordinates of the points without returning to any competent
authorities to avoid any administrative and computational
complexities.
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.
This paper presents an overview of AVASAG; an ongoing applied-research project developing a text-to-sign-language translation system for public services. We describe the scientific innovation points (geometry-based SL-description, 3D animation and video corpus, simplified annotation scheme, motion capture strategy) and the overall translation pipeline.
