| Abstract | ||||
| This paper presents a new methodology to connect the surveying process directly with accurate geodatabase at 3D Geographical Information System (GIS) for any urban space without re-entering the surveyed data. This procedure conserves time and effort in studying and developing various urban projects whether current or extended. Additionally, the proposed approach is based on integrating the used surveyed systems with the appropriate geospatial surveyed software side by side using Building Information Modeling (BIM) for studying all details of the architectural objects into a geo-context. Accordingly, a dedicated proposed framework is proposed to develop the urban studies especially the development of the 3D geospatial models. The latter explores the importance of spatial relationships in surveying systems for different urban spaces that comprise a multilayer of analysis. Firstly, the spatial data of studied urban space is analyzed based on the database extracted from the surveyed systems used. Then, exporting this digitized data to ArcGIS software to build and analyze the urban space under study as a geospatial Model. Thus, the planner defines the required functions and urban needs that are be implemented in the study area. Secondly, using advanced geospatial surveyed software based on the concept of the highest reality and accurate database to link with the geospatial model. Finally, the last stage integrates the results obtained from the different surveyed systems and software used. Consequently, this paper introduces the effective contribution of the appropriate integrated system with an accurate geodatabase that redounds to taking appropriate planning decisions to develop or re-plan the presented urban project. | ||||
