# Outerview Global Road Signs Index

A large-scale geospatial index of road signs and traffic signage with latitude and longitude.

This dataset is part of Outerview’s mission to organize the world’s physical infrastructure and make it searchable, measurable, and continuously updated.

---

## 🌍 Overview

- **Feature:** Road signs and traffic signage  
- **Scope:** Global  
- **Entries:** 15,000  
- **Total Index:** Millions of locations (full system)  
- **Formats:** Parquet / CSV / GeoJSON  

This index represents a **subset of a much larger global system** tracking road infrastructure and signage across the world.

Each row corresponds to a real-world road sign observed at a specific location.

---

## 🌎 Why This Index Exists

Road signs are a critical layer of **navigation, safety, and infrastructure intelligence**.

This index is designed to support a **continuous stream of real-world data**, enabling:

- Tracking changes to road signage over time  
- Detecting newly added, removed, or damaged signs  
- Improving navigation systems and map accuracy  
- Supporting autonomous driving and routing systems  
- Monitoring infrastructure consistency across regions  

Our goal is simple:  
**maintain a living, global index of road signals that reflects how roads evolve in real time.**

## 📊 Index Schema

| Column        | Description |
|--------------|------------|
| id           | Unique identifier |
| latitude     | Latitude coordinate |
| longitude    | Longitude coordinate |
| region       | Administrative region |
| source       | Data source |

## 🧠 Data Sources & Labeling

- **Imagery Source:** Mapillary  
- **Index Generation:** Outerview AI models  

All detections were generated using Outerview’s computer vision systems trained on large-scale real-world imagery.

---

## 🧪 Example Use Cases

- Train models for traffic sign recognition  
- Improve navigation and routing systems  
- Support autonomous vehicle perception systems  
- Monitor road infrastructure changes over time  
- Build geospatial search and world modeling systems
