There are several fields in Land that may be used for collecting Evidence of Contamination
Evidence of Contamination
| Standard values
|
| Indirect
|
Direct
|
None
|
Not Specified
|
Indirect Evidence
Which type of Indirect Evidence should be specified and the standard values should be customised to the Mine Action Programmes's Nation Mine Action Standard (NMAS) because the what is considered to be Indirect Evidence in one MAP may be considered as Direct Evidence in another MAP.
| Standard values
|
| Evidence from old survey
|
Former combatant zone
|
Mine/ERW accidents with unknown location
|
Mine/ERW records (low reliability)
|
Productive land not in use
|
Verbal reports
|
Not Specified
|
Direct Evidence
Which type of Direct Evidence should be specified and the standard values should be customised to the Mine Action Programmes's Nation Mine Action Standard (NMAS) because the what is considered to be Direct Evidence in one MAP may be considered as Indirect Evidence in another MAP.
| Standard values
|
| Detonations
|
Mine/ERW accidents with known location
|
Mine/ERW records (high reliability)
|
Mine signs, fencing, etc.
|
Visual observations
|
Not Specified
|
Land classification (former Mine Action Area Type)
Depending on Evidence of Contamination and which Type of Contamination / Ordnance Land is classified as:
| Classification
|
Definition
|
Contamination
|
| Indication
|
Used for inaccessible areas or areas with limited information available
|
Mines / UXO
|
| SHA
|
Strong indication of mine/ERW contamination on the basis of Indirect Evidence
|
Mines / UXO
|
| CHA
|
Confirmed contamination on the basis of direct evidence of the presence of mines/ERW
|
Mines / UXO
|
| Ammunition storage / Stockpile
|
The ordnance is stored in e.g. an armoury or a warehouse
|
All types
|
| EOD Spot task
|
May be subsurface or surface
|
Not mines
|
Ordnance Classification (former Device Classification)
This field has existed in IMSMA before V6.0.
