GroundTruth - Community Situational Awareness

Key Features

What GroundTruth Provides

A comprehensive situational awareness platform powered by community observations and smart verification.

🔔

Proximity Alerts

Get instant audio and vibration alerts when verified incidents are reported within 1 mile of your location. Never miss critical information.

📊

Confidence Scoring

Every report has a 0-100% confidence score based on corroboration, time clustering, and spatial analysis. Higher scores = more reliable.

🗺️

Live Map View

See all active reports on an interactive map. View locally or switch to USA-wide view to see nationwide patterns.

✅

Clear Reports

If you pass a location and don't see the reported condition, submit a "clear" report to help reduce false positives.

🔒

Privacy First

No accounts, no tracking. Ephemeral sessions rotate automatically. Your identity is never stored or linked to reports.

🛡️

Anti-Spam Protection

Multi-layer verification prevents fake reports. Rate limiting, device fingerprinting, dwell time checks, and movement plausibility ensure accurate data.

🌍

Multi-Language

Full support for English, Spanish, French, Arabic, Chinese, and Vietnamese. Right-to-left text support included.

📋 Important Information

All reports represent community observations and are provided for situational awareness only. Reports are protected by multi-layer anti-spam verification including rate limiting, device fingerprinting, and movement analysis to ensure accuracy. GroundTruth does not verify reports through official sources. Confidence scores indicate corroboration levels, not authoritative confirmation. User discretion is advised.

How It Works

Confidence-Based Verification

Unlike simple binary systems, GroundTruth calculates a confidence score (0-100%) based on multiple verification factors.

80-100%

High Confidence

Full audio + vibration alerts. Multiple corroborating reports.

60-79%

Medium Confidence

Optional alerts (user setting). Some corroboration exists.

30-59%

Low Confidence

Map display only. Limited verification.

#

Report Count

More unique reporters corroborating the same incident increases confidence significantly.

⏱️

Time Clustering

Reports within 15 minutes of each other add a clustering bonus to confidence.

📍

Spatial Clustering

Reports from nearby locations (tight clustering) weigh more than spread-out reports.

📉

Time Decay

Confidence naturally decreases over time. Clear reports accelerate this process.

Privacy by Design

Your Privacy Protected

GroundTruth is built with privacy as a core principle. No accounts, no persistent tracking.

🔄

Rotating Sessions

Session identifiers rotate automatically. No persistent tracking of individual reporters.

#️⃣

One-Way Hashing

Reporter information is cryptographically hashed. Cannot be traced back to individuals.

📱

Client-Side Processing

Proximity alerts calculated on your device, reducing centralized data exposure.
