Ghost Planet allows investigators to record evidence during paranormal investigations using multiple capture methods. Evidence is organized into collections that include text notes, audio recordings, photos, and EVPs (Electronic Voice Phenomena).

​
Evidence Types

Ghost Planet supports four types of evidence:
  • Text Notes: Written observations with subject and detailed body
  • Audio Notes: Voice recordings and ambient audio (max 5 MB)
  • Photos: Visual evidence in JPEG, PNG, or WebP format (max 5 MB)
  • EVPs: Audio recordings marked as potential Electronic Voice Phenomena

}

​
Evidence Data Structure

All evidence types are bundled together in a single evidence package: 
{
  "investigation_id": 42,
  "location_id": 15,
  "created_by_user_id": 101,
  "visibility": true,
  "text_notes": [
    {
      "subject": "Initial observations",
      "body": "Detailed description of phenomena...",
      "location_id": 15
    }
  ],
  "audio_notes": [
    {
      "title": "EVP Session 1",
      "source_url": "https://storage.example.com/audio.mp3",
      "file_size_bytes": 2458624,
      "is_evp": true
    }
  ],
  "photos": [
    {
      "source_url": "https://storage.example.com/photo.jpg",
      "caption": "Anomaly in frame",
      "file_type": "jpeg",
      "file_size_bytes": 3145728
    }
  ]
}
The created_at timestamp and evidence id are automatically generated when you submit. You don’t need to provide these fields.

Best Practices

​
During Active Investigations

  1. Capture immediately: Record evidence as phenomena occur rather than relying on memory later
  2. Add context: Include detailed descriptions in text notes to contextualize audio and photo evidence
  3. Mark EVPs clearly: Use the EVP flag to distinguish potential paranormal audio from regular recordings
  4. Check file sizes: Stay under the 5 MB limit to ensure uploads succeed

​
For Desktop Uploads

  1. Organize first: Sort your evidence files before uploading
  2. Name files descriptively: Use clear file names like “basement-cold-spot-001.jpg”
  3. Batch similar evidence: Upload related photos together for easier organization
  4. Write comprehensive notes: Desktop mode allows for more detailed text note composition

​
Privacy and Sharing

  1. Set appropriate visibility: Use private mode for sensitive locations or ongoing investigations
  2. Review before publishing: Double-check public evidence for personal information
  3. Coordinate with team: Ensure all investigators agree on visibility settings

​
Troubleshooting

Your file exceeds the 5 MB limit. Compress the file or reduce quality:
  • For photos: Reduce resolution or use higher JPEG compression
  • For audio: Use lower bitrate MP3 encoding (128 kbps recommended)
Only JPEG, JPG, PNG, and WebP formats are supported. Convert your image:
  • Use an image editor to save as JPEG or PNG
  • Ensure the file extension matches the actual format
The subject field is required for text notes and cannot be empty:
  • Enter a brief description of the observation
  • Keep it under 500 characters
Check these common issues:
  • Verify the evidence visibility setting matches your view filter
  • Ensure you’re viewing the correct investigation
  • Refresh the page to load the latest data
