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

Read Quick Start first - https://github.com/ugcs/UgCS-GeoHammer/wiki/Quick-Start

Main features and functions:

  • Windows and Mac OS support
  • import of GPR data in SEG-Y and GSSI DZT formats
  • display data tracks on the map
  • 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
  • data gridding and export as GeoTiff images for CSV data
  • customizable templates for CSV data import, out of the box GeoHammer has import templates for following data formats:
    • SPH Engineering's SkyHub data log (position.csv file)
    • SPH Engineering MagNIMBUS magnetometer
    • SENSYS MagDrone R4, R3, R1 data files (ASC format)
    • SENSYS MagDrone R1 raw data files
    • Medusa MS series gamma ray spectrometers CSV files
    • Geometrics MagArrow
    • GEM Systems GSMP-25/35
