• Land Area : 330.000 km2
• Population : 88 million people (2010)
• Urbanization : 30% (2010)
• Upcoming Plans:
- To be industrialized country by 2020
- To develop a strategy for NSDI in Vietnam with the vision to 2020
A large amount of spatial data in various scales is available to access:
Topographic mapScale: 1:250000 to 1:10000Coverage: Nationalwide
3D map
Satellite images
Land use map1:50000 to 1:1000Coverage: Provinces Cadastral map1:1000 to 1: 200Coverage: Cities
Geodetic network 1st and 2nd orderCoverage: Nationalwide
Geodetic and elevation control pointsSea water levelDEMGeoid surfaceDrainage systemTransportation systemAdministrative boundarySatellite imagesLand useCadastreLand valuePopulation and economic infrastructure distributionSea bed topography
Problems:
• Duplication on Data production
• Poor of data sharing
• Data standard
• Lack of management skills
• Individual cannot get spatial data.
• Policy on the development of spatial data is unclear

In order to utilize spatial data efficiently…

National Spatial Data Infrastructure (NSDI)National Spatial Data Infrastructure (NSDI)
Name: National Spatial Data Infrastructure (NSDI)
Temporal scope: ~2020 year
Purpose: To establish a concise plan to drive State’s activities toward the development of the National Spatial Data Infrastructure
Scope:
1.To eliminate redundant spatial data
2.To encourage data sharing
3.To have decision making through spatial analysis
4.To make spatial data widespread in the society
5.To reduce cost and budgets

There are 7 components were proposed for National Spatial Data Infrastructure
1. Framework Spatial data
2. Standards
3. Access to data
4. Technology
5. Policy – Legislation
6. Organization – Institution
7. Partnership
Asia Geospatial Forum 2013
Framework spatial data includes 7 layers, same as layers
from 1:10000 scale topographic map.
1. Vegetation
2. Administrative border
3. Topography
4. Hydrology
5. Transportation
6. Population distribution
7. Satellite images.

Surveying and Mapping activities in Vietnam are
following these standards:
• National Mapping Standard (2005)
• National Database Standard (2005).
• Geographic Data Standard (2009)
• Cadastral Data Standard (2010).
• Land registration standards
• Law of Survey and Mapping (doing)
Standard of spatial data contents, data exchange, meta-
data and data services

Data discovery, data access and data process
Only State’s Institution and companies can access
spatial data. It is necessary to overcome information
monopoly data center by issuing legal regulations, policies
to facilitate access to spatial data.
Asia Geospatial Forum 2013
Hardware and Software Equipment, Data Communication Network.
Technologies from Intergraph and ESRI are mainly
used to make and edit spatial data.
Surveying and mapping technology has been completely
changed into digital.
Technologies for data securities and automatic
updating spatial data in a huge database are getting very
important.
Asia Geospatial Forum 2013
National Assembly and Government have paid much
attention to legal frame and policy on ICT application and
e-Government.
NSDI development strategy is expected to be approved
by Prime Minster in 2014, and also Law on NSDI is
approved by National Assembly adopts in 2017.

State budget spends about USD 100 million/year
for encouraging communities to participate in NSDI

teaching survey-mapping, land administration and other
related subjects.

Data production from State’s companies will be transferred to those from the local and privates companies. Spatial data will be update from the local to those of government center.

At present, State budget is investing about:
USD 40 million / year for cadastral works 。USD 74 million / year for production and upgrade of spatial data.
USD 1 million / year for spatial data network construction.
USD 2 million / year for spatial data production technology.
Vietnam does not have an official guidelines for the
development of NSDI yet. Local enterprise scares to do
business with spatial information. Lack of investment to spatial
data.
Still long way to go…
