Municipalities and industries such as oil and gas
are gathering new data on old pipelines
For years, engineers and owners of pressurized pipelines have been seeking better ways to monitor the condition of buried pipes. In lieu of exposing pipes for inspection, pipeline owners have used various types of remotely controlled probes, cameras, and other devices to obtain information about underground pipes. The oil and gas industries have largely led the charge, driven by regulations and risks associated with catastrophic failures and explosions.
Recent developments indicate that petroleum industry techniques can be tailored for municipal applications, such as water distribution pipelines. Robotic systems are offering new capabilities in obtaining real-time data, capturing the attention of budget-conscious owners of aging infrastructure systems. The July explosion of a steam pipeline in New York City provided a wake-up call that buried utility pipes cannot be considered out of sight, out of mind. Read more>>

Google's massive database of geospatial data includes street mapping, satellite and aerial photographs, digital terrain model data, and more. This incredible resource is available for browsing through a free utility called Google Earth. Imagery and terrain models accessible through Google Earth can be imported directly into Civil 3D with a minimum of fuss, making for an extremely useful feature set. In the last "CAD Clinic" column, we introduced this topic by describing the data available, as well as the steps required to import those images and terrain models. This month, we conclude our review of using Google Earth and Civil 3D by considering coordinate system issues and by looking at the Publish to Google Earth tool. Read more>>
