This is a submission for the Redis AI Challenge: Beyond the Cache.
What I Built
Control Points Finder – Real-Time Geospatial Intelligence for Field Engineers Powered by Redis Cloud
Control Points Finder is a mobile-first geospatial search and navigation tool designed for surveyors, GIS specialists, and field engineers in Ghana. It solves a critical problem: locating verified control points quickly and accurately in the field.
Built with Flutter and powered by Redis Cloud, the app uses Redis not just as a cache—but as a primary database, full-text search engine, and real-time geospatial query layer.
🚀 Redis Capabilities
Redis powers the Control Points Finder with multi-model intelligence far beyond caching:
| 🔧 Capability | 💡 Description |
|---|---|
| 🔍 Fuzzy Full-Text Search | Search control point IDs and town names with flexible matching |
| 🌍 Geospatial Radius Filtering | Instantly find nearby control points using location-based queries |
| ✨ Autocomplete Suggestions | Live input matching with prefix and wildcard logic |
| 📇 Dynamic Metadata Display | Coordinate conversions and rich data cards for each control point |
| 🧵 Real-Time CLI Access | Direct querying and validation using Redis CLI |
🔧 Key Features & CLI Examples
1️⃣ Full-Text Search by Town Name
FT.SEARCH control_points_idx "@town:(Tema)" RETURN 3 id town location
2️⃣ Geospatial Radius Search
FT.SEARCH control_points_idx "@location:[5.5882 -0.1751 10 km]" RETURN 3 id town location
Result: Returns control points like:
SGGA C2600 17 4
SGGA 935/01/1 (ADGIRIGANO)
SGGA 7/89/106 (SPINTEX RD)
3️⃣ Autocomplete with Live Suggestions
Typing "SG" returns:
- SGGA C2600 17 4
- SGGA 935/01/1 (ADGIRIGANO)
- SGGA 7/91/640 (TEMA)
4️⃣ Dynamic Card Display
Each control point card includes:
🆔 ID, 🏙️ Town, 📍 Coordinates
📐 Original Easting/Northing
🏷️ Label and Redis Cloud source
🧭 Navigate button to Google Maps
🧰 Tech Stack
🐍 Python – GeoJSON to Redis Cloud loader for control point ingestion
| 🧱 Layer | ⚙️ Tool |
|---|---|

- 🧮 Preserves legacy coordinate systems for compatibility
🏁 Final Thoughts
Redis didn’t just support this project—it enabled it. From full-text search to geospatial intelligence, Redis proved it’s more than a cache. It’s a real-time, multi-model powerhouse that’s ready for the field.
Control Points Finder is a testament to Redis’s versatility, speed, and reliability. And it’s already making a difference in how engineers work.

How I Used Redis 8
Redis was the backbone of this project — not just for caching, but for powering intelligent, real-time geospatial workflows.
🔧 Redis Capabilities Used
Primary Database: All control point data stored as Redis JSON objects
RediSearch: Full-text search on town names and control point IDs
GEO Indexing: Radius-based location filtering for field proximity queries
Autocomplete: Live suggestions based on partial input using prefix and wildcard matching
Redis CLI: Used for direct querying, debugging, and validating search logic
🧪 Redis CLI Examples**
KEYS cp:*
Returns all control points in the Redis database
FT.SEARCH control_points_idx "@location:[5.5882 -0.1751 10 km]" RETURN 3 id town location
Returns all control points within 10 km of a given location
FT.SEARCH control_points_idx "@town_tag:{TEMA}" RETURN 3 id town_text location
Returns all control points located in Tema
