Destructive Tree Sampling (DTS) makes it easy to measure overbark and underbark diameters up the stem of felled trees. You simply create a template on the web at destructivetreesampling.com.au. Download your template to an android device and measure the trees in the field. When you have completed measurement, send the data back to the web at destructivetreesampling.com.au where you can download the data, analyse or load into your own system.
