Research On The Management Information System Of The Ancient Tree In The Summer Palace Based On WebGIS

Ancient and famous trees which are rare at home and abroad have historical value and commemorative significance.Those trees have important scientific research value.As more and more attention has been paid to ecological protection,the protection of ancient and famous trees is becoming particularly important.The manual recording was mostly used in the traditional information management of ancient and famous trees.However,the data is easy to lose,the query efficiency is low,and the content is not comprehensive.The intelligent terminal based on mobile internet technology is applied to the information management system of ancient and famous trees,which can make the system more scientific and efficient.In this paper,the management information system of the Summer Palace ancient tree based on WebGIS is researched and developed.This system is designed according to the MVP architecture mode and is developed by Android Studio.According to the actual needs of the management and maintenance of ancient trees in the park,the main functional modules are:ancient tree information collection module,WebGIS map module and ancient tree information management module1.Development of the ancient tree information collection module:call the system camera and rewrite the camera bottom preview interface,and consistent with the screen Ruler line.According to the actual height of the reference object and the camera distance,the appropriate pixel factor is adjusted,and the height and the breast diameter of the old tree are calculated according to the distance from the measured ancient tree.2.Research and implementation of WebGIS based map module:Select the development method of Server API-based Ajax control in WebGIS technology,adopt the software development kit provided in the official development platform of Amap,realize positioning,add Marker icon,mobile icon in this module of path planning,and navigation.At the same time,the function module interface can also directly scan and recognize the two-dimensional code,and rely on the ZXing dependent package method to parse the scan result and obtain the data.3.Research and development of the ancient tree information management module:Using the Android native database SQLite database technology to realize the classification and preservation of the ancient tree inspection data,query the inspection data according to the ancient tree number and the inspection date,and display the latest inspection record.The management system of the ancient tree designed in this paper has been applied and promoted in the Summer Palace scenic spot.The practical application results show that the system has perfect functions and good user experience to meet the actual design requirements.
