摘要
针对目前管线大数据量数据库难以在移动端加载问题,同时顾及管线外业数据采集内外业一体化、离线保密等测量作业需求,本文基于GPKG(GeoPackage)数据库,使用ArcGIS Runtime API for Android开发包,设计并开发一款管线外业调查的离线式Android端软件。软件通过数据库MDB到GPKG转化方式,解决了大数据量数据库管线图流畅显示问题;使用GPKG数据库存储卫星影像切片,可以离线加载大区域的卫星影像,并且实现管线数据的采集基本功能。测试软件测试实验显示,十万级别数量的管线以及GB级别的卫星影像切片均可在秒内加载和显示。
This paper aims to solve the problem that it is difficult to load large volume databases in pipelines on mobile devices and considering surveying needs of indoor and outdoor research integration and offline confidentiality,etc.It designs and develops an offline Android application for outdoor surveying of pipelines based on the GeoPackage(GPKG)database and ArcGIS Runtime API for the Android development package.The application solves the problem of smooth display of large volume database pipeline map via database conversion from MDB to GPKG.Meanwhile,satellite images in large areas can be loaded offline by the GPKG database to store satellite image tiles.Moreover,the basic functions of pipeline data collection are all realized in this application.The application test experiments show that 100000 pipelines and gigabytes of satellite image tiles can be loaded and displayed in one second.
