... 5 Veer-Off Reporting and Data Collection As noted earlier, the basis for developing veer-off location models was information obtained from aircraft accident and incident reports available from several databases in the U.S. and countries with aviation accident rates comparable to those verified in the U.S.

... 6including historical satellite pictures, were used to infer the approximate veer-off path of the aircraft. Location References Used Longitudinal Distances Longitudinal distances were measured from the runway threshold for landing and from the beginning of the takeoff roll for takeoff operations.
From page 7...
... 7 In addition, the runway distance available was divided into 20 subsections, 10 on each runway side, as shown in Figure 3. The length of each subsection varied according to the normalization procedure used for measuring longitudinal distances, as explained later in Chapter 5.
