SPH Engineering's GeoHammer is a simple to use tool to quickly assess and process GPR (ground penetrating radar) and CSV data from various sensors (magnetometers, metal detectors, gamma-radiation spectrometers, etc.).

Particularly useful as a data processing tool in the field, the interface is optimized for maximum simplicity and ease of use.

Main features and functions:

• Windows and Mac OS (Apple Silicon) support
• import of GPR data in SEG-Y and GSSI DZT formats
• import of Cerulean Sonar SVLOG files recorded for Cerulean Surveyor 240-16 MBES and Cerulean OmniScan 450
• display data tracks on the map
• data geotagging using POS files or precise flight tracks as source
• split data to separate lines - described in Quick Start
• most popular processing options covering majority of applications for scenarios like utilities and other man-made objects detection:
  • background removal and contrast (gain) adjustment for GPR data
  • low-pass filtering for CSV data
  • GNSS time-lag compensation (CSV)
  • data quality check for coverage and altitude range (CSV)
  • running median filtering to highlight anomalies in the data
• setting marks in the data
• export marks in KML format
• generate and export amplitude maps as geotagged GeoTiff images for GPR data
