"WMATA Metrorail Using ¡®Big Data¡¯ to Install Cellular Service" ¡ª¡ª Passenger Transport
Description:
¡°In the U.S., mobile LiDAR mapping technology had not been used in tunnels on any known project more than five miles in length,¡± Falken said. Metrorail engaged Maser Consulting, P.A., an engineering firm specializing in geospatial services, to test the mobile technology on a five-mile section.
The demonstration was successful. Next, the engineering firm made the ¡°big data¡± readily available to Metrorail engineers and the cellular companies using uGRIDD infrastructure data management service, which allows users to view, measure, extract and download information in a secure server environment...

Description: ¡°With the LiDAR data stored on uGRIDD anyone can zoom down a 360 degree LiDAR depiction of a rail line and find the data you need. It avoids time intensive and costly field work,¡± said Jim Harper, CTA chief engineer for infrastructure.Harper believes that asbuilt dimensions of the CTA rail infrastructure provided by LiDAR will help to create a good capital asset inventory of the system, improving capital asset management and application of CTA¡¯s limited capital improvement funds. .... ...
