Rail Radar^® practical approach for positional referencing:

• locates data features
• compares and analyzes different data collection points
• provides accurate positional referencing for all data

Rail Radar^® positional referencing approach combines Differential Global Positioning System (DGPS) and accurate linear referencing which includes rail landmark feature tie-in. Rail Radar^® referencing also facilitates the identification in the field of localized subsurface anomalies identified during post-processing. All survey data components:

• are linearly and spatially referenced
• allows for accurate reporting of inventory, condition assessment and detected anomaly results
• simplifies the integration of all reported data into geographical information system (GIS) based track-management systems.

Synchronization of Data

• Tie imagery and ballast radar data are synchronized with onboard high accuracy linear and spatial referencing systems.
• All survey data is collected continuously at survey vehicle speed, with additional landmarks directly encoded into the data stream (mileposts, etc).

Spatial Referencing and Life Cycle Cost Analysis
The rigorous Rail Radar^® approach to referencing accuracy provides temporal stability for all collected data, and allows year-after-year condition assessment comparisons and track infrastructure performance modeling.

• Rail Radar^® is capable of providing accurate spatial referencing in any client specified coordinate system or projection.
• This capability allows the straight forward integration of data into existing Track Management Systems using any commercial GIS format.

This makes possible life-cycle cost analysis (LCC) to determine the most cost-effective approach for construction, rehabilitation and maintenance strategies allowing the estimate of time and costs at the network or project level.
