GIS Navigator assisted RAF Lakenheath to address utility network challenges, specifically in electricity, water, sewer and gas, by enhancing infrastructure management through Geographic Information System tools. The project begins with extracting BIM and CAD models data and converting it into GIS compatible formats and creating utility network datasets. Spatial analysis, such as georeferencing, vector model based tasks including digitisation and topology, and populating the Data, were utilised to visualise and organise data within GIS. The Result? A database containing multiple datasets that supports RAF Lakenheath in making strategic decisions about utility layout and infrastructure planning, leading to improved long-term management and network efficiency.
