PUBLIC OPEN-DATA COLLECTION AND VISUALIZATION BASED ON HTML5: MOBILE WEB APPROACH

摘要

A mobile web application performs specific tasks with digital contents on mobile web browsers in any place and any time. Mobile web technologies for service development or target-oriented application system implementations are mostly based on HyperText Markup Language5 (HTML5) to perform core functionalities from client-side. Among several useful APIs of HTML5, indexedDB provides off-line data storage capacity to support dual-mode of off-line and on-line processing. While, public open data policy in government organizations or agencies in most countries provides Open API or of downloading numerous types of geo-based data sets for mobile mashup or fusion applications. These data sets contain base map of Open Street Map (OSM) or other mapping servers, multiple types of vector layers and multi-resolution satellite images. Data sets generated from both natural environment and man-made environment, if they are freely accessible public open data, is considered as significant geo-based data contents to solve many real world problems. This study is to design and implement system about public open data collection and visualization, including geo-based data. As well, mobile visualization processor also provides through dashboard in an integrated environment. This implementation was carried out by fully open source stack and linkage approach such as Spring framework for common components and Bootstrap for client interface, without any commercialized software or proprietary tools. Conclusively, the implemented product and unique results by this approach can play a role to develop geo-based mobile application fields using many kinds of open sources and multiple types of public open data.
