T4A Maps QA
T4A Maps QA is made available ONLY to T4A Data Members who actively submit data. It is therefore NOT a free download for everybody, but is posted ONLY to active data member.

It is important to note that the T4A Maps QA is NOT a navigational toolkit, it is just a 2-dimensional map (lines and points) which serves ONLY as a quality control tool so that Data Members are able to check whether their data submissions (lines and points) have been processed correctly. T4A Maps QA is updated MONTHLY, with version numbers such as 6.09 (2006 September), 7.06 (2007 June), etc.
