The Digital Gravelometer has a host of features to improve your productivity, giving you the information you need – fast.

Key features include:

  • Intuitive, easy-to-use graphical interface
  • Extensive documentation and guidance on field procedures
  • Based on proven technology and thorough testing, published in Water Resources Research and Mathematical Geology
  • Does not require calibration at each field site (but full control of grain-measurement parameters is enabled)
  • Batch processing of samples (put the kettle on whilst the Digital Gravelometer processes your images)
  • View (and save) intermediate steps in the grain-measurement processes to permit verification of the output from the grain-recognition procedures
  • Customisable grain-size analysis report including:
    • User defined or default percentile estimates (in mm, phi and psi)
    • Standard grain-size distribution statistics (mean, sorting, skewness, kurtosis) based on moment or graphical methods using logarithmic, geometric and arithmetic methods
    • Proportion of grains in Wentworth size classes, standard sieve size classes or user-defined classes
    • Fully customisable graphical representation of the grain-size distribution as a histogram and cumulative curve
    • Information about the project (client, operator etc.) and each individual image (filename, sample ID, collection date etc.)
  • Output grain-size distribution analysis report to a web browser for viewing and printing, or export to a comma-separated variable file for further analysis
  • Undertake analysis on a cumulative percent finer or coarser basis
  • Combine grain-size information from multiple images into a single aggregated sample
  • User defined upper and lower grain-size truncations
  • Output on a grid-by-number or area-by-number basis
  • Export raw grain-size, orientation, and shape information

Digital Gravelometer is a work-in-progress and we are constantly seeking ways to improve it based on feedback from our users. If you have a suggestion for how it can be developed to better meet your needs, please let us know by e-mailing us via info@sedimetrics.com.
