GIS for Land-use and housing management
GIS MODEL OF DISTRICT 5 OF HCMC
In order to keep with an existing official management, the system should be a centralised one. This centralised system needs one server computer that stores all of GIS data in one geodatabase while other client computers connect to the server to exchange data through a backbone network.
In this model, the server should be located at the People's Committee Office of District 5 while other clients are located at their places in the committee precinct. In general, the GIS of District 5 will be a professional system with six components: Hardware, Software, Data, Procedure, Orgaware, and Humanware. However, in order to reuse effectively old land-use and housing information stored on paper maps, this project is considered as the first stage of implementing a professional system concentrated on building up a database and automating some necessary functional procedures.

Consequently, the first version of DIGIS would:
- Hardware: Take full advantage of existing hardware including workstation computers, printers, and other devices.
- Software: Reuse operating software and be equipped with ArcView GIS 3.2.
- Data: Gather all of existing data, put them all together to be ready for updating and retreiving by any GISs. That was an important objective of this project. Data of DIGIS were designed into 2 types: basic data and thematic data. Thematic data could be created from paper or digital maps, statistical tables, or other documents. All of paper-based data were vectorized into computer as shapefile data. However, this issue could not be finished at an expected time because some data were being completed, especially the planning data, parallelly with the project. At the end of the project, over 15 spatial data layers and many non-spatial data tables were achieved for DIGIS.
- Procedures: Automate some principal business processes as automatic procedures. They have made the system more effective. Procedures were classified into five toolboxes: core applications toolbox, planning applications toolbox, land-use and housing's applications toolbox, public work's applications toolbox, and state house's applications toolbox.
- Organisation: Not be mentioned in this version of the project. A framework for the system is needed to make it more professional. However, due to the scope of this version of the project, this job will be done in the next project.
- Training: Train basic knowledge for the district's staffs. This is one of the important issues to make the system available soon. The project got enthusiasm of the district's staffs. Over 15 people were taught the basic GIS and how to use DIGIS tools.
In summary, the aims of the project were established at 3 components of GIS: Data, Procedures, and Training. In the future projects, all of six components of GIS should be considered to build up a more professional system to help the local government improve their managing tasks and widen their services to the citizen.
