【摘要】：随着时代的发展,各种技术的更新换代,森林资源调查作为林业工作至关重要的一个环节,也需要随着时代的发展而改变。随着林业装备信息化和精准林业理论体系的不断发展,森林资源调查设备与森林资源调查理论不断的革新升级,森林资源调查设备从传统的皮尺、到全站仪、再到今天的MINI超站仪,不断地走向便携化。本文所研究的森林资源调查PDA技术是从林业手持式测量装备、林业手持式记录装备以及云端云计算技术三个层面上提出一套涵盖测量、记录、计算、统计绘图和云端数据管理等功能为一体的完整解决方案。本文所研制的森林资源调查PDA,是以嵌入式开发为核心,使用ARM与WinCE开发的林业手持式测量装备,主要提供了树木胸径、树高、方位角,以及地理坐标的测量。以移动端混合开发为核心,使用Android与Cordova开发的林业手持式记录装备,主要提供了树木样地内外业一体化的记录计算功能,数据可视化与统计功能,同时通过移动端的网络模块能使用云端提供的数据服务。本文所开发的云端服务器应用程序,是以阿里云服务器后台开发为核心,使用MEAN Stack全栈技术提供了REST风格的数据服务,以及导出Excel表格的功能。本文所设计和研发的森林资源调查PDA,其创新性特点在于：1、解决方案提供了测量、记录、计算、统计、绘图和云计算以及数据处理从头到尾的整套业务流。2、解决方案针对林分观测,林木模型提出了新的算法。3、解决方案通过对硬件测量仪器与移动端、云端业务的结合,解决了传统林业手持式设备在计算、存储、可视化上的不足。4、解决方案使用C/S和B/S混合架构和NoSQL,构建了与云端结合的内外业-体化森林资源调查解决方案。
[Abstract]:With the development of the times and the upgrading of various technologies, forest resource investigation, as a crucial link of forestry work, also needs to change with the development of the times. With the continuous development of forestry equipment informatization and precision forestry theory system, forest resources investigation equipment and forest resources investigation theory are constantly innovating and upgrading. Forest resources investigation equipment ranges from traditional tape ruler to total station instrument. Then to today's MINI super station instrument, unceasingly moves toward the portable. In this paper, the PDA technology of forest resource survey is proposed from three aspects of forestry hand-held measuring equipment, forestry hand-held recording equipment and cloud computing technology. Statistical mapping and cloud data management and other functions as one of the complete solution. The forest resource survey PDAs developed in this paper are based on embedded development and developed with ARM and WinCE. They mainly provide the measurement of tree DBH, tree height, azimuth and geographical coordinates. With the mobile terminal mixed development as the core, the forestry hand-held recording equipment developed by Android and Cordova mainly provides the record calculation function, data visualization and statistics function of tree sample land and field. At the same time through the mobile network module can use the data services provided by the cloud. The cloud server application developed in this paper is based on the background development of Ali cloud server. It provides REST style data service with MEAN Stack full stack technology and the function of exporting Excel tables. The Forest Resources Survey (PDAs), designed and developed in this paper, is innovative in that it provides measurements, records, calculations, statistics and solutions. Mapping and cloud computing and data processing a complete set of business flow. 2, the solution for forest observation, tree model proposed a new algorithm. 3, the solution through the hardware measurement instrument and mobile, cloud business integration, It solves the shortcomings of traditional forestry hand-held equipment in computing, storage and visualization. The solution uses C / S and B / S hybrid architecture and NoSQL, and constructs a solution for the investigation of forest resources in the field and outside industry combined with cloud.
