Abstract

-Each surveying project is unique and requires a specific surveying technique. The problem lies in that not only all techniques are not suitable for all kinds of surveying projects, but also The wrong choice of the appropriate surveying method for the building can cost a lot of time and effort or cause damage to the heritage building. Individually, any surveying project depends on many factors that describe its “nature” and affect the selection of the appropriate surveying method, These factors may vary from the cost to the required degree of accuracy, or the number of existing details required to be scanned in the heritage building… etc. Therefore, this paper aims to develop a proposed methodology to choose the most suitable surveying method according to each surveying project’s nature. The project’s nature has been described in this paper through several factors deduced from studying modern 3D surveying methods. The paper discusses the common modern 3D surveying methods which are Laser Scanning and Photogrammetry and elicits their characteristics and affecting aspects. Complex structures may now be efficiently and correctly recorded remotely thanks to these technologies, which was not possible with earlier survey techniques. This paper, also, follows an analytical approach to prove the effectiveness of the project’s nature factors in selecting the most suitable surveying method, by analyzing several case studies of surveying projects according to the project's nature factors. As a result, a methodology for choosing the most appropriate surveying method according to the project’s nature has been deduced.
