    8. Brief introduction of service Relevant links List of reference E-learning Q&A Promote popularity Download data for free This is homepage, the web address is http://ngisdata.moi.gov.tw

    9. Latest News and Popular Data (Including subscription to RSS) Information and Web Services Displayed on the Homepage : • Latest News • Popular Metadata • Application for Popular Data • Application for Popular Services • Subscription Service to RSS for Users to Update Information

    10. Search for Metadata Functionality: Providing user with a variety of ways to search for metadata which contain spatial representation information, coordinate system, data contact information, distribution information, data quality information, and more as to achieve the goal of data circulation.

    11. Data Category User can search for metadata according to nine data categories on homepage which are natural environment, natural resources and ecology, environment quality, social economy, transportation network, land information, land-use planning, public pipeline and topographic map.

    12. Data Circulation User can have online services through this platform which are: • Application for data and map services • E- payment • Data and map services Download This functionality is to facilitate data circulation.

    13. Web Service Functionality The web service functionality can provide data services and function services. For example, it can publish WMS (Web Map Services) of 1/1000 of topographic map, which is data service. Coordinate transformation service and address positioning service are function services. This functionality enable user to search for services online and apply for online services though our platform. User could retrieve and interact with remote sources of map service directly by user’s own application system, which could reduce developing cost and time, which facilitate development and application of NGIS.
