Locate anomalies for further assessment
The purpose of the magnetic survey is to record and interpret variations in the magnetic field. These may indicate buried objects, but can also arise from other sources in the ground or surrounding infrastructure. The results provide a basis for further assessment by the specialists responsible for the project. Magnetic detection alone does not establish the identity or condition of an object and does not constitute clearance of a site.
Survey design matters
Target size, expected burial conditions, sensor clearance, line spacing and background interference influence detectability. Vegetation, terrain and obstacles may limit how closely and consistently the sensors can follow the ground. These conditions need to be considered when defining the survey area, coverage requirements and interpretation scope.
Agree the information needed for follow-up
Discuss the required anomaly mapping, location information and reporting with MGT before the survey. The agreed results should help the project team understand where further assessment is needed and where measurement constraints affect confidence.
Information for an initial discussion
- Location and approximate size of the investigation area.
- Known site history and the types of objects of concern.
- Existing survey information, where available.
- Vegetation, surface conditions and nearby infrastructure.
- Requirements of the specialist team responsible for follow-up.
