Richie 330 Posted June 17, 2016 You don't need to enter any values for height of sea level etc in TB, your height data contains that already. Just set easting to 200000 and northing to 0 If your sea is not water and deep then set them manually using L3DT 1 Share this post Link to post Share on other sites
g50st 1 Posted June 17, 2016 ok do i manually have to lower sea level or is there an option Share this post Link to post Share on other sites
Richie 330 Posted June 17, 2016 You would just have to set the height as a negative value in L3DT the apply the areas using the 'set to' tool in L3DT , -40 is the norm but you want some shallow areas round the coast/beach areas, i normally go from -1 to -10 meters then smooth it. 1 Share this post Link to post Share on other sites
