Working with the Georgia Department of Transportation in the US I developed a model reconstruction and semantic enrichment engine that can digitize the 15,000 highway bridges for asset management in the state of Georgia. Working with Network Rail in the UK I developed a new structural inspection system using photogrammetry to replace the traditional, dangerous, inefficient, and non-informatic inspection approach for examining 30,000 ageing railway bridges. • Ma, L.*, Sacks, R., et al.
