Archaeological and forensic investigations are often expensive and time-consuming, and there is always a risk of missing significant targets. A ground-penetrating radar survey can efficiently map landscape-scale subsurface targets, facilitating a more refined and informed investigation. GPR data can reveal vertical and horizontal relationships between important archaeological and landscape features, such as buried structures, wells and privies, and historical roads. These data can then be used to guide excavation efforts and minimize impacts to the landscape.

GPR data from a buried historical structure, showing time slice data at multiple depths. With data like these, excavation planning can incorporate horizontal and vertical anomaly patterning, and assess important areas for archaeological ground-truthing or resource avoidance. For analysis purposes, time slice data can reveal contextual information regarding site layout and the spatial relationship between features.
