Aiming at demand of automation and integration of portable equipments used in forest survey,a handheld type multifunctional gauge,GForest,is designed with a prototype. GForest integrates height indicator,angle gauge and the computation of forest stand's volume all together and thus has functions including measurement,data storage and camputation and other functions. GForest realizes anti-shake design through sampling control algorithm,use counter to store and control result of angle gauge counting and share datas with other equipments such as PCs and mobile intelligent terminal through USB port,aiming to solve problem of desynchrony of development of informationization of hardware equipments used for data collection in forest ground survey and data collection software. By this design,GForest can reduce hand works of data recording and typing-in in forest outdoor survey by a large extent and improve efficiency of outdoor data collection,through test and verification,the tested average error of tree height measurement using GForest is 4%,which shows the same outstanding performance as the similar import devices,furthermore,it has utility functions of angle gauge winding test and control,and has obvious advantage in cost which makes GForest suitable for application in industry.
