Bland-Altman plots illustrating the agreement of mean distance from home (a), maximum distance from home (b), convex hull (c) and standard deviational ellipse (SDE) (d) derived from the map-based assessment (MBA) and GPS measurements. The continuous horizontal line shows the mean difference between measurements by the two methods; the dashed lines show the limits of agreement, defined as the mean difference plus and minus 1.96 times the standard deviation of the differences
