A Repeatable Site Survey: Mapping Rooms, Sensors, Witness Positions and Environmental Conditions
A site survey turns an unfamiliar building into a documented research environment. Without a map, investigators may not know where a sound was recorded, how far a witness stood from a doorway or whether a sensor was moved between sessions. Repeatability begins with spatial documentation.
Create a site plan. Sketch the accessible areas and label rooms, corridors, stairways, windows, doors and connected spaces. Add approximate dimensions and a north arrow if orientation can be established. Mark restricted or unsafe zones separately.
Record positions. Give every sensor a unique identifier. Note its coordinates or measured distance from fixed landmarks, height, orientation and mounting surface. Photograph each position from more than one angle. Do not rely on memory or informal labels such as “near the old door.”
Map witness locations. Record where each observer was positioned and which direction they faced. Include sight lines, obstructions and likely sound paths. This can help assess whether two people had comparable access to an event.
Environmental context. Note building materials, lighting, HVAC, electrical equipment, nearby roads, occupancy and weather. Record doors and windows as open, closed or partially open. Include a time-stamped activity log.
Repeat survey. At the beginning and end of each session, check whether equipment or site conditions changed. If furniture, doors or sensors moved, update the plan and note the time. A site map is a living record, not a decorative diagram.
Privacy and security. Do not publish precise layouts of private residences, security systems or sensitive locations without permission. Store access-controlled maps securely and share only what is necessary for the research report.
Conclusion. A repeatable site survey makes evidence easier to interpret and allows independent teams to test the same conditions. Good mapping is one of the simplest ways to improve the quality of field research.

AERM Research and Reporting Checklist
Before publication, confirm that the report:
- States the question and the observation separately from any interpretation.
- Identifies the location and conditions at a level that respects privacy and safety.
- Records equipment, settings, placement and known limitations.
- Preserves original files and documents any processing.
- Describes controls, alternative explanations and unsuccessful tests.
- Reports uncertainty and avoids claims stronger than the evidence.
- Has permission for all identifiable recordings, quotations and images.
AERM Core Principle: No anomaly is considered paranormal until environmental, psychological, technical, and scientific explanations have been systematically evaluated.
About AERM
Anomalous Evidence Research & Media (AERM) is a research and media initiative focused on structured investigation, evidence preservation and public science communication. Through its research publication work and the Paranormal Frame platform, AERM aims to make complex scientific ideas accessible while maintaining a clear distinction between observation, interpretation and established evidence.
