النمذجة الكارتوغرافية لعمليات الإزاحة الأفقية بين الخرائط الطبوغرافية و المرئيات الفضائية لمناطق مختارة من العراق باستخدام RS GIS

الملخص EN

Iraq's topographic maps suffer horizontal displacement when compared with space visualizations, a vertical exaggeration that distorts during the preparation of the spatial database, and is the basis for the construction of digital cartographic modeling.

Therefore, model construction suffers distortion as a result of horizontal displacement by circularization, And satellite Image.

The basic idea was to apply the algorithm of H.

Kohorst for horizontal displacement in a statistical manner within the ArcGis environment.

This study was designed to achieve the possibility of addressing the distortion of horizontal and vertical exaggerations, either cartographically or cartographically.

The use of the analytical method and the use of methods of statistical analysis, remote sensing, geographic information systems, maps and digital cartographic techniques, the most important digital techniques (Gps- Digital Map- Geo Statistical Analysis) and the use of topographic maps 1: 100000 prepared in the General Survey Authority Baghdad, satellite data (Landsat 30 meters and 15 meters).

Was applied to a study on selected models of Iraq Rawanduz for the mountainous region and Xuan for the mountainous and coastal region of the Plateau and Basrah for sedimentary plain.

The study concludes that maps suffer from distortions due to geographic projection and generalization.

Maps 1: 100000, and distortion of digital cartographic models due to the horizontal displacement of errors in data sources, differences in measurements, projections and erosion, the study recommends applying these mechanisms and standards to large scale maps to build an effective and useful database in planning processes The holistic development of an era has become a digital technique and models that mimic the reality and the main actor of decision makers.
