Conclusion ULU Need:
A process to highlight the possible existence of historical tram infrastructure prior to ULU field investigation
ULU Solution: A GIS tram database integrated into the units working methodology
Result: GIS database derived from historical documents which provides a spatial and time reference of the historical Sydney tram network over the years 1921 to 1954
