Digital Gravelometer由拉夫堡大学地理系的David Graham博士，Ian Reid教授和Stephen Rice博士开发。数字砂砾仪使您能够从数码照片中快速准确地测量未固结的砾石沉积物。使用数字砂砾计，您可以显着提高生产力，从而获得暴露的砾石样本，获得与使用传统技术获得的精度类似的尺寸信息。收集样本与拍摄数码照片一样简单 – 只需遵循一些简单的指南和“快照”。在一天结束时，将图像传输到您的计算机上并将其载入数字Gravelometer软件。关于每个图像和几次鼠标点击的一些基本信息都是获得样本的完整粒度分布所需的全部信息。除了基本的尺寸分布参数外，Digital Gravelometer还生成可自定义的报告，其中包含大量统计参数以及图形颗粒尺寸分布曲线和直方图。一旦您对报告进行了定制以适应您的特定要求，设置可以保存为模板，从而使后续样本的分析更加快速。如果您希望进行数字砂砾仪支持以外的分析，则可以将报告导出到逗号分隔的变量文件，该文件可以被大多数数据分析软件包（包括Excel）读取。
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).
