Data for the four individual blocks have been integrated using a grid-based differential continuation onto a sloping plane (1500′ above sea level SE to 3700′ above sea level NW) to produce a single grid over the entire survey area. This gridded data set with maps is available as an optional deliverable. Survey Size: 5,198 line
