Cloud computing, the prevailing and rapidly emerging technology, has become mainstream in most of the industries. Developed by the Information Center, Ministry of The Interior, Taiwan Geospatial One-Stop (TGOS) is the portal which enables users to search, view, query, and access the geospatial data and the web services in Taiwan.
Serving as the geodatabase and web service provider, TGOS contains comprehensive query catalog, Metadata database of national spatial data, and web services, helping government, organizations, academic institutions, and citizens to find information like contents, data providers (departments), and usage limits of the required geodata through searching Metadata on TGOS.
The public spatial data in Taiwan are owned by different departments. To effectively lower the cost of repeated service maintenance of the systems for government institutes, TGOS Cloud is developed to collect, store, and process the spatial data from local governments and then publish diverse APIs such as TGOS MAP API to integrate with their own data.
The existing TGOS only served to collect spatial data and offer physical files. In response to the recent expansion of system requirements, TGOS Cloud aims to fully support the original systems, to demonstrate the functionality such as membership database, browsing authority of spatial data, and service registration management, and to enable users to integrate the spatial data that will be processed and served as APIs on the TGOS portal.
In this project, SuperGIS Server 3 allows TGOS users to create, manage and distribute spatial data as GIS services including map services, feature services, and OGC services and unify map tile types to reduce labor cost in data preparation for government departments. Moreover, the server GIS ensures that new GIS services can be overlaid with the existing ones and easily applied to various mobile applications using Map API.
TGOS MAP API is classified into five elements, including the basic and advanced Web-controllers, stacking for map elements, data structures, and other located services. Users can use frequently-used essential base maps and manipulation tools to display the map data.
TGOS Cloud provides end-users with the ability to query data or employ application with pre-generated base maps. By accessing the TGOS Cloud system for TGOS MAP API and Network Service, users can develop their own map services using TGOS MAP API and achieve seamless data fusion in TGOS database for Web GIS and Mobile GIS applications.
With the development of TGOS Cloud, it facilitates organizations to integrate and publish spatial data as diverse services via connecting with TGOS services. Consequently, users are not only able to apply Map API offered by TGOS Cloud to conduct various analyses such as route analysis and buffer analysis but also to effectively manage their map websites without paying huge costs to publish maps.
