Surveying and Mapping
The survey unit maintains a national database of UXO information:
impacted villages; the workplans and completed tasks of the field teams;
and historical bombing records. The data is maintained in a geographic information
system, which facilitates the printing of maps and summary statistics for
general and specific areas of interest.
UXO LAO has now received all US historical records of air combat
operations in South-east Asia from 1965-1975. These databases provide valuable
information on the type, quantity and locations of ordnance dropped.
The data is primarily used to create maps of the areas of potential
UXO contamination for provinces, districts, and specific areas of interest
like individual villages, roads or power lines.

UXO LAO has provided several hundred maps in response to requests from
a range of Lao government ministries for information about potential contamination
in areas selected for bilateral or multi-lateral development projects. In addition
to providing historical records, the US Government continued to provide
funds for specialised technical support for the survey unit: this includes
assistance in managing the data, producing maps and training UXO LAO staff.
Community Awareness teams now collect information to update the Level One
(General) Survey data. This, published in 1997, continues to provide
baseline information for workplanning. Level Two (technical) surveying was recently
introduced in the Programme. Survey teams visit contaminated
villages and record detailed information about the locations of ordnance visible
on the surface of the ground and define the perimeter of sites contaminated
with sub-surface UXO. This new activity will increase the efficiency of the
roving and clearance teams.
National standards have been adopted for Level One, Two and Three Mine Action
Survey reports. Level Three (Clearance completion Report) survey
documents are produced by field teams and forwarded to the National Office for
updating clearance records and archiving.
