2 Topography of Clifton suspension Bridge – Business case

Because this project is being done for charity, Clifton Suspension bridge, it is mandatory to utilise all free models, materials, and plugins. The visualised information model will be used to find clashes through visualisation, and it contains asset information in an aesthetically pleasing model (Knott and passe, 2021). The model should be ready to be imported and used by the sandbox arena platform. Because this model is open for everyone to use, it is being challenged to make it more acceptable for a project's tender stage, to aid in educating staff and BIM specialists, and to provide a visualisation impact that will assist future projects (Knott and passe, 2021). COWI addressed all of these concerns during the Kick - off meeting.

The project is been executed by a group of five different individuals where in this piece of the report is being discussed on the topography of the project. The main objective is to have georeferenced topography.

2 TOPOGRAPHY OF CLIFTON SUSPENSION BRIDGE –

BUSINESS CASE STUDY

According to the Cambridge dictionary, topography is defined as the aesthetic appearances of a land's natural characteristics, particularly the pattern of its surface (topography., 2022). When we say topography, we mean components like land, roads, trees, and rocks. The key factors evaluated throughout this project are having a georeferenced model, the model's aesthetics, and its accuracy. By breaking down the process into topography and other, they are explained in detailed below.

2.1 TOPOGRAPHY

The main objective of the topography is that it should be georeferenced. In the process of achieving that objective three different methods were tried in three different tools they are by using displacement map, using ArcGIS SDK plugin, and using Blender GIS. The more detail explanation of its application and its limitations are explained below. When talking about georeferencing it is important to understand the term georeferencing. It is nothing but the coordination of the visualized data to the real world data (USGS, 2022). This can be done by adding geospatial data to the game engine (Laksono and Aditya, 2019). An object, event, or phenomenon that has a location on the surface of the earth is considered geospatial data (Stock and Guesgen, 2016).
