| The effective protection of forest resources and ecological environment is an important foundation for sustainable development of human society.The forest area of our country is vast,and the forest resources are various,and the forest patrol inspection is an effective way to guarantee the healthy growth of the forest area.However in the present many problems in the inspection technologies used in most of the forest,complex operation,low efficiency,such as inspection process inspection result report and feedback lag,the inspection work assessment and management is not perfect,low accuracy of forest area of surveying and mapping.Aiming at the problems that exist in the way of inspection and the actual goal of forest management,this paper proposes a based on Android mobile platform,combined with GPS/BDS dual-mode positioning and "Internet+" model of intelligent inspection system of surrveying and mapping.The main research contents and work described in this paper are as follows:Through field investigation in the forest now patrol the present situation of the management,an area of surveying and mapping technology,consult the related literature about the corresponding technology research status at home and abroad,analyses problems of existing technology,and integrating the actual goal of forest management,forest intelligent inspection system was designed and implemented the information platform.The integration platform of forest information management is composed of intelligent mobile inspection instrument,cloud server,cloud database and Web management and dispatching center.The key design has completed the intelligent forest mobile inspection of the Android terminal software.Introduces the software adopts the MVP of the infrastructure,each function module includes checking dot positioning,inspection tasks of intelligent planning,inspection records and history records management,query,data report beidou short message function modules such as the specific implementation method,and designs and realizes forest inspection path optimization method;Embedded geographical information mapping algorithm in the inspection software.Combined with geographic coordinates information algorithm,and realized the earth WGS84 coordinate system and the local coordinate system of xi ’an in China between 80 transformation,based on Mercator algorithm for latitude and longitude coordinates to plane km network coordinate transformation,and by using vector calculation algorithm to realize the local area of forest triangle area;JiuFeng forest farm in Beijing and henan longyuan flowers and trees bases on the system function and system accuracy test algorithm.Experimental results show that the system in the dot inspection,inspection records,inspection plan,the short message communication which implements the functions such as intelligence,on the functional can completely meet the needs of forest daily patrol management.On the other hand,the average error of the forest area with the system mapping is less than 2%,and the sampling average error is less than 3%,which can fully satisfy the demand for surveying and mapping accuracy in forest engineering. |
