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.
