5 5 Geometry data comprises shot and receiver numbers and locations, elevation data, shot depth and uphole times (if available) First break picks can be imported if picked in external packageĦ 6 The ray trace method of model based First Break pick analysis can be computer intensive when dealing in 3D Ray tracing can be speeded up if the survey area is rotated to a north-south orientation which simplifies the trigonometryħ 7 The data in the survey are extrapolated to a north-south grid if a rotation is not applied.
