  1. Building GIS as platform for e-government Tran Kiem Dung Senior Consultant - DTT Hanoi, 2012

  2. Content • Current status of GIS technology in e-government project • DTT point of view on GIS in DN Egov Platform

  3. 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.

  4. 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.

  5. Existing issues

  6. 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. • WorldView satellite's image with its resolution of 0.6m

  7. 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

  8. Cadastral map database

  9. Topographic map database

  10. Database of satellite’s image with its high resolution

  11. Satellite’s image updated to 2012 for Da Nang City

  12. 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

  13. 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.

  14. Map Index of topographic map in Da Nang

  15. 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

  17. 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 serviceapplications on unified base map across the city. Implementation model will be a CityGIS with all necessary functions for urban management.

  18. 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)
