Forest inspection is an important work for forest resources investigation, disaster warning and ecological protection, and the realtime and effective mapping of the inspection area is very important. Aiming at some problems in the surveying and mapping technology of forest inspection area, including not high efficiency and accuracy. Intelligent surveying strategy based on Beidou navigation satellite system (BDS), combing Android intelligent operating system was proposed. The method of intelligent optimization forest patrol task planning path, the calculation method of forest patrol area and the intelligent sampling method based on the Beidou positioning technology combined with Android were designed. The intelligent patrol network platform based on “Internet plus” was established, and the hardware platform by using the BD-228 positioning module and the STM32 was developed. The visual map kit Baidu LBS SDK was integrated into the system to display the sampling points, and the distance offset filtering algorithm was implemented to eliminate the point that the error was too large. Then the coordinates of longitude and latitude were projected into Mercator coordinates for area calculation. Finally, the area of the inspection trajectory was calculated by using the vector triangular area algorithm. At the same time, the intelligent acquisition of sample coordinates was realized by using Mercator. Through multiarea and multifield test verification analysis, the average error of the system survey area was less than 2%, and the average error of sample acquisition was 2.21%. Thus this method can meet the requirements of forest engineering surveying and mapping.
