Creating geo-spatial locations for 130 stations
The first stage of the project was to geospatially insert over 130 stations into the company’s master technical map the London Survey Grid system. Over time LUL will be able to enrich the information held about the stations to include ‘as-built’ or new project drawings.
Multiple drawing files had to be pieced together using internal documents including old drawings featuring station entrances and exits, OS maps, and track plans to create the station layouts.
The next stage was to add polylines for each of the rooms in the stations and then tag the data with relevant information. This information included the station name, room number, which floor it was on, and what the room was used for, which were also obtained from the internal documents mentioned above.
