Abstract:
A Geographic Information System (GIS) is a technology designed to collect, store, analyze, manage, display, and update location-based data, integrating diverse data types from various sources. A critical component of GIS is its database, which organizes and stores data in a structured format, enabling the efficient retrieval and management of primary information. The geographic database plays an important role in various fields, including socio-economic development, national security and defense, natural resource and environmental management, transportation, and the exploitation of natural resources. The urban technical infrastructure database is one of the key databases supporting the development of smart cities.
Purpose. To develop a multipurpose geographic database at a scale of 1:2,000 for Ho Chi Minh City region, Vietnam, from which data layers will be extracted to support the management of urban technical infrastructure in the study area.
Methodology. The research consists of several essential steps, including LiDAR scanning, digital photography, data collection and processing, digital image mapping, standardization of digital elevation models, vectorization of geographic features, and field investigations to gather attribute data for geographic objects. Subsequently, the process involves integrating specialized maps with existing 1:2,000-scale topographic maps to standardize the geographic data. The next phase focuses on building a geographic database and editing the 1:2,000-scale topographic map using ArcGIS. Finally, data layers related to urban technical infrastructure will be extracted from the geographic database.
Findings. The geographic database was developed consisting of seven groups – borders, hydrology, surveying, population, topography, traffic, and surface coverage, and a 1:2,000-scale topographic map of Ho Chi Minh City was created. Additionally, basic urban technical infrastructure data layers were extracted from the geographic database to support urban infrastructure management.
Originality. This study is the first to establish a geographic database at a 1:2,000 scale and extract urban infrastructure data layers from it for the experimental area of Ho Chi Minh City, Vietnam.
Practical value. The research results will enhance the information system supporting urban technical infrastructure management, enabling local authorities to develop appropriate policies and streamline management processes more efficiently and effectively.
Keywords: geographic database, urban infrastructure, technical infrastructure management, Ho Chi Minh City, Vietnam
