Abstract Ground Penetrating Radar (GPR) is a critical non-destructive geophysical method used in civil engineering, archaeology, and utility mapping. A recurring operational challenge is the efficient transfer of processed data—specifically horizontal time-slices (amplitude maps)—from acquisition systems to analysis platforms. This paper defines the "GPR Slice Download" process, examines current data formats, evaluates transfer methodologies, and proposes best practices to ensure data integrity and interpretability. 1. Introduction Modern GPR systems generate dense volumes of data comprising hundreds of A-scans per meter. While real-time vertical profiles (wiggle traces or colorized sections) are useful for on-site decision-making, detailed subsurface analysis often relies on depth slices (also called time-slices or C-scans). These slices represent horizontal plan-view amplitudes at specific depth intervals, enabling detection of linear utilities, buried structures, or stratigraphic changes.
