The Mapping of the Magnetic Traverses in Forestry Summary Because of the characteristics of the object »-forest« the magnetic compass measurements will not lose their importance in forestry in spite of the possibilities of the forest cartography improvement using e. g. aerial photography. The magnetic compass measurements in the terrain will probably not change important in the future, but with hardware and software improvement the graphicah method of the adjustment of the magnetic traverses will be abondoned in favour of the numerical one. This made necessary to establish the formula for the allowable error of closure for numerical adjusted magnetic traverses. The errors in graphical adjustment are calculated by (1) and (2), in forestry mostly by (3). Analising the accuracy achieved by own measurements (Fig. 2) it was concluded that (4) or simplified (4a) used for traversing for topographic survey are not sutable for numerical adjustment of magnetic traverses and is proposed to use (5), where [d] is the total length of the traverse. |
