  • The NGIS project in Taiwan

  • Major achievements

  • Emerging Technologies

  • Strategies

  • Conclusions

Spatial data infrastructure
Spatial Data Infrastructure

  • Geographic Information Systems (GIS) is a ‘new’ technology to collect, digitize, analyze, and share spatial data.

  • GIS, together with GPS and remote sensing, becomes an essential part of spatial data infrastructure in many countries.

The ngis project
The NGIS Project

  • In 1994, Taiwan launched her National GIS project and established a task force to implement the project.

  • The task force is co-chaired by deputy-ministers of the Ministry of Interior (MOI) and Council of Economic Planning and Development (CEPD). Members are from related ministries and local governments.

Ngis goal
NGIS -- Goal

Building up high-quality base maps and circulation environment for

  • Sustainable development

  • Administrative governance and international competitiveness

  • National Land Use Management

  • Natural disaster response and prevention

  • E-commerce

  • Awareness of public policies

  • Academic researches

Ngis organization
NGIS -- organization

  • Nowadays, the task force has 10 working groups.

    • A planning group is responsible for strategic planning and standardization.

    • 9 database groups are responsible for building up and maintaining base maps concerning topography, land ownerships, land use and control, transportation, natural resources, environment management, agriculture, socio-economics, etc.

Ngis the 1 st phase
NGIS – the 1st Phase

  • 1998-2003

  • 44 sub-projects in 4 categories:

  • GIS has been applied to government administration affairs, engineering, natural and social sciences, and public health.

  • Archived maps are still needed to be digitized, vectorized and further utilized.

  • Historians have employed GIS/ GPS/ Satellite images/ Google Earth to explore facts in ancient time.

  • There is a strong link with library science in terms of meta-data, map/ feature/ location finding, and knowledge management.
