The SPH Engineering GPR Basics – Data Processing & Interpretation (GPR-2) training is the second-level GPR course, focused on processing, interpreting, and delivering results from airborne GPR survey data. Building on the system operation and data acquisition skills covered in GPR-1, this course equips operators with the practical skills to process SEG-Y GPR datasets in Prism 2, interpret radargrams for subsurface target identification, and produce professional deliverables for utility detection, void mapping, and pavement assessment projects.Training is delivered at the SPH Engineering office or via video conferencing. Price is per group of up to 4 students.Prerequisites Completed GPR on a UAV – Level 1 (GPR-1) training (or equivalent knowledge and field experience) Access to GPR datasets for processing exercises (own survey data or SPH Engineering-provided sample datasets) Training Outline GPR Data Fundamentals — Understanding SEG-Y format, trace geotagging, and the structure of airborne GPR datasets acquired via SkyHub Prism 2 Software Introduction — Overview of the Prism 2 data acquisition and processing software interface, project setup, and data import workflow Basic GPR Processing — Applying standard processing steps: time-zero correction, background removal, gain adjustment, filtering, and migration for improved target resolution Radargram Interpretation — Reading and interpreting GPR radargrams: identifying hyperbolic reflections, layer boundaries, voids, and subsurface anomalies Velocity Analysis & Depth Estimation — Determining signal velocity in the ground medium and converting two-way travel time to depth for accurate target depth estimation GIS Export & Deliverable Generation — Exporting processed GPR data and interpreted results to GIS-compatible formats for client reporting and regulatory documentation Practical Exercises — Processing and interpreting real GPR datasets from airborne surveys, identifying targets, and producing deliverable outputs Delivery Details Location: SPH Engineering office or remote via video conferencing Group Size: Up to 4 students per booking Price: Per group (up to 4 students)
