SGGP November 2, 2023 07:41

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 database conversion 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 handle operations and update in many other forms, such as directly updating via system functions, 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, prioritizing the updating of 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 journeys. The map system allows planning a journey from point A to point B quickly and conveniently, 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 scene.

Easy to provide

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 the entire Ho Chi Minh City area (instead of using Google map, Openstreet map...) requires agencies and units to publicize data types under their management; at the same time, share databases through APIs.

The digital map system of Ho Chi Minh City 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 data on the shared digital map system 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 to the public, agencies, and units in the city so that they can know and respond to contribute to building, using, and effectively exploiting the system.

Ho Chi Minh City Digital Map is a digital map platform used for the entire city, replacing map applications such as Openstreet Map, Google map. The system provides a diverse collection of base maps, including administrative maps, traffic maps, topographic maps, and satellite maps.

On the digital map, data is regularly updated from official information sources, integrated from departments, branches, districts, towns, and cities in the area. With this application, users can also share information about locations with others via Facebook, Zalo, Twitter, Email, Telegram, QR...
