Current status of GIS technology in e-government
project (1)

GIS technology has been used in Vietnam since 90s and
applied in many fields of state management such as land,
mineral resource, environment, agriculture, climate change
etc management.

Some leading GIS technologies as ESRI, Intergraph, MapInfo,
Autodesk ...have been used in many projects. Open source of
OSGeo and some other solutions have been put into practice
in many places

GIS has been used to develop CityGis in many provinces like
HCMC, Hanoi, Hue, Danang….but not completely successfully
yet.

Current status of GIS technology in e-government
project (2)

GIS has been applied in many fields as natural resource and
environment, construction, agriculture and climate change.

Base map (cadastral and topographic) has been invested and
developed in Central level nd Provincial projects but most of
them seem to be not updated.

There is not completely applied and updated CityGIS system
providing spatial data lookup and integration tool with State
database.

Existing issues
Develop GIS applications that
are independent on database
collection and processing
system
• GIS data systems have not been updated
• It spends much money to collect and standardize
data to put them into GIS system
Use many kind of basemap
• It is impossible to integrate data due to
difference from coordinate system
• It is impossible to use some free or open data
sources as Google Map, OpenStreetMap...
Lack of data sharing policy
• It spends much money on duplicate data
collection in many projects
• It is unclear in identify data management and
updating responsibility, causing fragmented data

DTT point of view on GIS in DN Egov Platform (2)

GIS data is developed on the same unified base map
including:
Database of cadastral map 1:500. This database contains
boundaries of Land Parcel, land for transportation, water surface
area and information related to legality of land parcel.
 Database of Topographic map 1:2,000 and 1: 5,000 (urban area),
1:10.000 rural area that is required 7 information groups:
topography, population, vegetation, transportation, hydrology,
administrative boundary and mathematical bases.

GIS is service platform
Geographical information
system of GIS is service
platform that is mainly
integrated to various
applications, also including
some following systems:
– Land usage management
– Construction authorization
management
– E-district/ E- ward
– Investment project
management

DTT point of view on GIS in DN Egov Platform (3)

Cadastral map database is commonly used for applications of land, construction,
transportation, planning, etc management

Database of topographic map should cover the whole Danang City, supporting all
public service applications.

Database of satellite’s image with its high resolution (more up-to-date than Google
Map, Bing Map) will be visual display for GIS system

There should be specific GIS information layer for each sector and they will be
updated by processing the public service profile

All GIS databases are managed centrally, assigned its updating task to each sector,
administrative agencies from all levels and shared common usage

GIS applications are integrated into public service application and city portal
12
Data current status of cadastral map

Cadastral map 1:500 is managed only by Department of Natural Resources
and Environment. This is highly legal database and updated by land
changes status.

There are digital cadastral maps in most of Danang districts now, excluding
Hoa Vang. They are all updated frequently by land changes. Danang has
transferred the cadastral map into centralized database (using ViLIS
software of Ministry of Natural Resource and Environment)

Department of Natural Resources and Environment submitted the master
project of land database developing to City’s People Committee, in which
there is new measurement of Hoa Vang as well as map data and cadastral
profile of districts standardization. Total investment value for this project is
about 300 billion.

Data current status of cadastral map(2)

Danang geographical map was drawn by images took from sky
view in 2003 and 2006. Thus, in comparison with current
status, there is lack of some updated information (on
transportation, population…)

Danang is not fully covered in area of topographic map with
ratio of 1: 2000 and 1: 5000

Topographic map database is currently managed in Measuring
Department of Department of Natural Resource and
Environment and transferred to Department of Information
and Communication for usage

DTT point of view on GIS in DN Egov Platform (1)

DTT recommended on bids to develop GIS as Platform, not
just as meeting specific applications as land management,
urban lighting and drainage.

Different from previous GIS development approaches of
Vietnam, Spatial data in GIS system of Danang will be updated
frequently through online public service applications on
unified base map across the city. Implementation model will
be a CityGIS with all necessary functions for urban
management.
17
Scenarios

Natural Resources and Environment Department updates, handles land changes,
releases land use certificate on database of cadastral map, manages environmental
issues as well as drainages on topographic.

Construction Department uses database of cadastral map to receive construction
permit submit letter, updates information of housing and construction works (detailed
drawing)

Transportation Department uses topographic map and cadastral map for general and
specific planning as well as urban lighting system management

Department of Planning and Investment uses databases of topographic map to manage
places of households, individuals and enterprises according to business registration
status in the city

Uses thematic maps to collect information on socio- economics across city to support
leader’s information needs.

.... (and many other applications depending on requirements from each unit)
