As smart water management initiatives advance, the industry is shifting from traditional, fragmented IT applications to a collaborative, digital, and intelligent management model.
Historically, water information systems have struggled with diverse data sources, isolated business systems, and scattered spatial information.
This lack of data sharing and collaboration across domains makes it difficult to support refined supervision and comprehensive decision-making.
To address this, the "One Map" platform leverages water census data and GIS spatial technology. It aggregates multi-source data—rivers, lakes, water conservancy projects, monitoring stations, and water resource management—onto a unified spatial base map.
This enables full-domain visualization, traceable business associations, and real-time operational awareness, providing digital support for water resource management, disaster prevention, and project supervision.
Overall Construction Concept
The "One Map" solution uses a GIS platform as its core, forming an integrated architecture of "Spatial Base — Data Resources — Business Applications."
By spatializing water objects, the platform maps reservoirs, sluice gates, pump stations, hydropower plants, and hydrological stations into a unified map system.
This shifts mnagement from fragmented records to spatial, visual oversight.
Furthermore, by linking project archives, real-time monitoring, historical data, and video feeds, the platform extends beyond "viewing a map" to "viewing business status," offering multi-dimensional analytical capabilities.
1. System Technical Architecture
GIS Spatial Foundation Layer:
The platform uses GIS as the unified spatial base for modeling and expressing water resources.
By loading foundational geographic information (basins, river systems, administrative regions), it maps all water projects and monitoring facilities onto a single map environment.
It supports standard map operations like zooming, regional positioning, and layer switching to meet diverse browsing needs.
Water Resource Data Layer:
The platform establishes a unified data management system that merges static archival data with dynamic operational data.
Resources include project basics, river/basin spatial info, hydrological and water withdrawal monitoring data, video surveillance, and management unit associations.
This standardized organization ensures data accuracy for map displays, business queries, and statistical analysis.
Data Fusion & Business Association Layer:
This layer fuses spatial and business data, expanding from simple location displays to comprehensive business information.
Clicking a target object on the map reveals its basic profile (name, code, basin, coordinates) and dynamic metrics (real-time water levels, flow rates, withdrawal volumes).
Through knowledge graph tags, the platform links upstream/downstream water systems, related projects, and withdrawal permits, building a comprehensive relational network for analytical support.
Business Application Layer:
Tailored to actual management needs, the platform constructs specialized applications for different scenarios:
- Water Resource Management & Allocation:
Unifies the display of withdrawal outlets, monitoring data, and business ledgers to support dynamic supervision and regional water replenishment.
- Flood & Drought Disaster Defense:
Combines hydrological monitoring, project info, and spatial distribution to quickly locate key areas and projects, aiding in flood dispatch and risk assessment.
- Video Inspection:
Integrates live video feeds linked to spatial locations, allowing remote viewing of reservoirs, rivers, and stations to improve inspection efficiency.
2. Core Functional Capabilities
- Full-Domain Visual Management:
Displays the spatial distribution of water resources, supporting combined queries by river system, management unit, administrative region, or project type to quickly locate targets.
- Multi-Dimensional Information Fusion:
Associates project archives, real-time monitoring, historical trends, and live video. Managers can view project statuses from a unified spatial entry point without switching between multiple systems.
- Statistical Analysis:
Provides comprehensive statistical panels displaying the quantity and distribution of various water objects using pie charts, bar charts, and trend graphs for quick overview and categorized viewing.
- Unified Resource Directory Management:
Supports establishing a resource directory for map objects, including names, codes, river/basin affiliations, and update times. Directories can be exported to facilitate resource management and business queries.
3. Application Value
Enhances Unified Management: Integrates scattered resources onto a GIS base, helping managers quickly grasp regional water resource layouts.
Supports Business Collaboration: Fuses static project info with dynamic operational states, providing intuitive data support for water dispatch, project supervision, and flood management.
Improves Refined Supervision: Drives the transition from fragmented management to digital, collaborative operations through unified data maintenance and specialized application development.
4. Future Outlook
Looking ahead, the "One Map" platform will continuously expand its business topics and data resources.
By connecting water resources, business applications, and management processes through a unified spatial base, it will provide a stable data foundation and scalable business support for the ongoing digital transformation of the water conservancy industry.
