What is NSDI ?
4NSDI : National Spatial Data Infrastructure
ICTcommon mapIT infrastructure to create, update, maintain and provide
geospatial information
Data Law
Map data(thematic map, common map)
Satellite imagery
Census/statistics
・NSDI law・Master plan・National Committee
Satellite positioning
lNSDI is a national platform to process, manage and provide geospatial data. The geospatial data contributes to national development in wide area, such as e-government, social infrastructure and land use management.lThe NSDI is comprised of ICT, Data and Law.

Recognizing crop growth condition from satellite imageryUsing satellite imagery, possible to estimate the growth of wheat or protein content in rice.
Growth level of each field

For wheat, enable to reduce wheat drying costs through timely harvesting and improve its quality.
For rice, it will help build a most efficient fertilization plan to support the stable production of high-quality rice.

Realization Steps for NSDI
24
lNSDI construction starts within ministries using maps frequentlylOther ministries and industrial sectors join step by step.
Small startMinistries in which maps are used frequently
New attendees expand uses of NSDI
F/S
Perticipation of industrial sectors
Ministries

Necessary Conditions for Success of NSDI PJ
25
Based on our past experience, the necessary conditions for success of NSDI projects are as follows
l Participants, ministries in Laos should be united under the project.- Consensus making
*Ministries should agree map data sharing among ministries
*Spatial object for map generation and map updating should be performed collectively
- Government committee or related institution to promote the project.
l Ministries should be coordinated- Committee or institution management- Leadership for consensus making- Management of working groups

Conclusion
26
l NSDI can be a national property.
l NSDI has great impacts on a lot of fields.Examples:*governmental administration ( mainly e-government )*social infrastructure construction*Creation of New IT industries*expansion of peoples’ welfare*environmenral conservation/natural resource management
l Spatial analyses based on “Big Data” processing and ICTplatform creates new application .
l Japanese team including Hitachi, Ltd. can be a big help to the realization of NSDI.
