The Department of Information and Communications of Ho Chi Minh City has just deployed the integration and sharing of the database of the Ho Chi Minh City digital map system, helping units and people exploit and use map data accurately and flexibly.

Many useful applications

The process of updating information for the map is being implemented by units and districts. Initially, the conversion of the initial database has been carried out, including 28 data layers of 5 units: Department of Transport (3 layers), Department of Natural Resources and Environment (19 layers); Department of Information and Communications (2 layers), Department of Construction (1 layer), City Electricity Corporation (3 layers). The map is updated via API (application programming interface) or providing an account to the implementing unit.

Units proactively process operations and update in many other forms, such as directly updating via operational functions on the system, updating a series of addresses in pre-formatted excel files. Up to now, units have updated data in real time using APIs of databases of Ho Chi Minh City Electricity Corporation, Ho Chi Minh City Water Supply Corporation, Department of Education and Training, Department of Transport, etc.

To build a digital map of Ho Chi Minh City, in phase 1, the Department of Information and Communications will coordinate with the Department of Construction, Department of Natural Resources and Environment, Department of Planning and Investment to update useful data to serve state management agencies and people. In the next phase, the Department of Information and Communications will provide accounts and authorize units to connect and update using professional software, with priority given to updating data managed by the unit such as health, education, etc.

According to Deputy Director of the Department of Information and Communications of Ho Chi Minh City Vo Thi Trung Trinh, because this is a base map with a scale of 1/2,000, 1/5,000, people do not have the right to update data to the system but can only send comments about the locations that people see as incorrect. At that time, the system administrator will conduct verification procedures and update the data according to people's comments. At the portal address www.bando. tphcm.gov.vn, people can exploit and plan smart trips. The map system allows quick and convenient planning of trips from point A to point B, while displaying traffic options and choosing the best route.

Digital maps also provide real-time traffic information, helping to avoid traffic jams and adjust travel schedules; information about the surrounding environment or determine your location... In particular, the digital map of Ho Chi Minh City applied on mobile phones allows users to collect data from many different sources and forms, including taking photos, recording audio, taking text notes or entering data from the field.

Provide easily

To become a digital map to replace other platforms requires a lot of effort and time. The implementation goal of the system is to provide a unified base map and data for departments, agencies (exploited via the web) and software systems (exploited via API). Therefore, having a unified digital map system, shared throughout Ho Chi Minh City (instead of using Google map, Openstreet map...) requires agencies and units to publicize data types under their management; at the same time, share databases via APIs.

The Ho Chi Minh City digital map system not only provides uniform geographic information, but also helps people and professionals access data easily through many different means. Through this platform, Ho Chi Minh City integrates spatial data and attributes of related units in the city, forming a shared data warehouse to serve sharing and exploitation for application software of agencies and units.

“The Department of Information and Communications has advised the Ho Chi Minh City People's Committee to issue regulations on the operation and exploitation of the shared digital map system data of Ho Chi Minh City. Priority will be given to connecting APIs to agencies and units that already have specialized professional systems in place to use, share, and create separate data layers for management purposes. Next is to deploy a system to store shared digital map data for the entire city on a shared data warehouse, then share data with agencies and units that need to exploit it according to regulations approved by the Ho Chi Minh City People's Committee,” said Ms. Vo Thi Trung Trinh.

In order for digital maps to replace other platforms, the leaders of the Department of Information and Communications hope to promote the system widely to people, agencies, and units in the city to know and respond to contribute to building, using, and effectively exploiting the system.
