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.
