Digital Gravelometer has been developed in the Department of Geography, Loughborough University, by Dr David Graham, Professor Ian Reid and Dr Stephen Rice. Digital Gravelometer enables you to measure unconsolidated gravel sediments rapidly and accurately from digital photographs. With Digital Gravelometer you can dramatically increase the productivity with which you sample exposed gravels, obtaining size information with a similar accuracy to that achieved using conventional techniques. Collecting a sample is as easy as taking a digital photograph – just follow a few simple guidelines and 'snap'. At the end of the day, transfer the images onto your computer and load them into the Digital Gravelometer software. A few basic pieces of information about each image and a few mouse clicks are all that is normally required to obtain a complete grain-size distribution for your samples. In addition to basic size-distribution parameters, Digital Gravelometer produces customisable reports containing a host of statistical parameters along with graphical grain-size distribution curves and histograms. Once you have customised the report to suit your particular requirements, the settings can be saved as a template, making the analysis of subsequent samples even quicker. In the event that you wish to undertake analysis beyond that supported by Digital Gravelometer, reports may be exported to a comma-separated variable file that is readable by most data analysis packages (including Excel)
