CBS Spatial Decision Support System

0
🎯 Problem

Location-based operational data was scattered across manual lists, local files, and disconnected field notes. This made it difficult to see what was happening in each region, compare locations, prioritize work, and report progress with confidence.

💡 Solution

Built a map-first CBS platform where spatial records can be viewed, filtered, enriched, and turned into practical reports. The system connects geographic context with business data, making every record easier to understand and every decision easier to justify.
