(1)System setting and being the portal of service provided the products of data manufactured by EPA in recent years, by using web-based interfaces. Project helped users realize the assistances of GIS by theme map.
(2)Making up policies of data sharing and SOP. Regulating the ways of obtaining data of users from EPA and out of EPA, it could make data interchanging more smooth. It also gave a midterm to long-term plan for GIS development of EPA as reference of future system developing.
(3)Integrating data and maps. The project integrated data manufactured by EPA and enhanced data interflowing and sharing.
(4)Joining and promotion. By applying technique of web map service and join NGIS alliance of MOI, service provided service of data viewing and system promotion, which will introduce harvest of this project to public.
