# GroundTruth — subsurface scan QA & trade estimating

> GroundTruth — subsurface scan QA & trade estimating — ai-gtfi-groundtruth. Use this tool when you need to accurately analyze subsurface scans and generate reliable trade estimates, as it solves problems related to do-not-core calls and reduces errors in GPR and pipe scan interpretations. GroundTruth takes subsurface scan data as input and outputs flagged areas and trade estimates, streamlining the QA process. It is ideal for use in construction, excavation, and infrastructure projects where subsurface accuracy is crucial.
