Relascope

The Spiegelrelaskop is a measuring instrument for detecting different waldwachstumskundlich relevant parameters. It was invented in 1955 by the Forest scientist Walter bitterly and is built since then in an unchanged form. Since then it is one of the most important international instruments in forestry.

Properties

A Spiegelrelaskop is about a fist-sized structure. With this relatively versatile measuring instrument can perform the Winkelzählprobe for recording the basal area. This size is important for the estimation of standing timber volume in forests. In addition, you can visually measure using the Spiegelrelaskops distances ( tree ) height, trunk diameter, slope in the terrain and other special waldwachstumskundliche parameters determine ( absolute form height, shape numbers, stem volume, as well as the inventory level by means Hirata ). For all measurements, the inclination is corrected automatically by the built-in drum pendant. For accurate measurement, the Spiegelrelaskop can be mounted on a special stand with lockable ball joints and extendable and pivotable center column.

A further development of Spiegelrelaskops is also for the purpose of precision measurements, designed by Walter bitterly Telerelaskop with an 8 -fold telescope magnification.
