A GeoPackage implementation of common map API on Google Maps and OpenLayers to manipulate agricultural data on mobile devices

摘要

Characterized by features of standards-based, platform-independent, portable, self-describing, and compact, GeoPackage, a new open format for geospatial information container, makes it much easier to manipulate geospatial data on mobile devices such as smartphones and tablets. In this paper, we present a GeoPackage based mobile application implementing Common Map API on both Google MapsTM and OpenLayers to assist in the manipulation of agricultural data on mobile devices. The app provides geospatial operations to access, manage, analyze, and visualize agricultural data on Google MapsTM and OpenLayers at the same time. Besides, by integrating with Apache Cordova architecture, users are able to run the app on multiple mobile platforms such as iOS and Android with little effort.
