ANALYSIS
UXOIntelligencen's experience, knowledge, databases, and archive collection allow unique analysis
results to be presented in a very short time.
By using only primary sources such as minelaying and minesweeping reports, war diary from minelaying units, sweep protocols and plots etc., a detailed and credible analysis result can be achieved, which can be presented in a simple and adapted way to the customer.
In the example below, a fictitious AOI has been used (green area).
Figure 1 shows the minefields/minelines that interfere or are in the immediate vicinity of AOI. Each
colour shows the type/types of mines that have been laid in each minefield.
Figure 1
Figure 2 shows the limited risk areas for each mine type. The risk areas are dimensioned based on
the positioning accuracy that prevailed when the respective minefield was laid. Since GPS had not yet
been invented during either the First or Second World War, positions could at best be determined
using landmarks such as lighthouses or beacons. In case of poor visibility, the position was calculated
by "dead reconning", ie. calculating current position by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time.
Depending on the navigational conditions prevailing at each individual mine laying, a position
uncertainty area has been assessed. This area is called “Mine Danger Area” (MDA).
Figure 2
Figure 3. All minefields are differently composed. Some consist of a few mines laid scattered in an
extensive area while others are dense and with mixed mine types. Thus, the risk of remaining mines
may vary depending on the composition of the minefields in question. By presenting the laying
pattern/density of mines in each minefield, the customer gets an idea of the risk that exists over the
entire AOI. Likewise, e.g. the normally difficult-to-detect non-ferrous mines are presented separately.
Figure 3
Figure 4. To dimension and plan the survey, Figure 4 shows which areas are contaminated and which
are not and thus do not need to be surveyed. UXOIntelligence analysis results allow the limitation of
areas that need to be surveyed, as well as detailed information on the number and types of mines
that are likely to remain within the AOI.
