Conclusions

Asia Geospatial Forum 2013


• 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

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


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.


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.


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.

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…


Thank you very much
