The Evolution of Traditional Urban Survey using Applicable Surveying Techniques
This research deals with how to facilitate and manage surveying methods to accomplish modernized and cost effective urban survey with best achievable accuracy. This is done by replacing traditional surveying methods with modern methods from both theoretical and practical point of view. At first, a theoretical assessment process on a tradition urban planning project in Saudi Arabia is performed by replacing traditional urban planning techniques previously used with more applicable surveying
... able surveying techniques as total stations regarding different matters such as applicability, cost and accuracy. After approving the main idea of this modernization process, a practical urban planning case study is performed using total station, geodetic GPS receivers and GPS navigators, on a private settlement block consisting of 6 buildings in a crowded neighborhood of Cairo city. The applied surveying techniques showed high efficiency regarding cost and effort, while saving observation time reaching to 60%. Accordingly, the adopted practical application proved to be beneficial for all desired aspects, as well as being promising for more extensive study areas in future.

III. URBAN SURVEY Urban planning is the discipline of land use planning which explores several aspects of the built and social environments of municipalities and communities. Other professions deal in more detail with a smaller scale of development, namely architecture, landscape architecture and urban design. Regional planning deals with a still larger scale. In terms of its objectives, planning is the elaboration of a set of related programs designed to achieve certain goal, while the planning process itself is the set of interventions and other actions undertaken during the elaboration of a plan. On the other hand, in terms of future control, it is the ability to control the future by current acts . Urban Survey Definition The urban survey concerns with the existing situation studies for an urban fabric context, which is a preparatory phase for analysis studies for the location to start further upgrading phases. This mentioned preparatory phase is very important as the accuracy of the related studies after that depends totally on the accuracy of this initial step. Accordingly, it is clearly essential to study and compare between different types and methods of urban survey, as to be able to reach the most accurate and progressive method to be used as a starting step in the right way of this long phases work. Urban Survey Types Here we need to define and study different variable types and methods, then subsequently, give fairly comparative analysis to illustrate the most effective, accurate, short timing and cheapest method. Consequently, several methods can be used to obtain the same main results with some differences in quality, details, accuracy, data covering and many fields' usages. The first type is the ordinary method by using the satellite images maps then start to update it by visual observations and non-accurate measurements of lengths and dimensions, then merging these drawn information by filled applications for all observed data to obtain finally the named fundamental maps, using geographic information system (GIS). This can be summarized clearly in five basic drawing sheets namely; land-uses, building uses, buildings heights, building conditions and building construction. An example of some of those sheets is given in Fig. 2.
