15. LKN-SH | BSHC Lidar Seminar | Lutz Christiansen | Hannover, 28.05.2014 Summary Laserbathymetry Dry land and shallow water areas without a gap Depth is dependend on turbidity Shallow water systems (1 Secchi-depth) Deep water systems (2 to 3 Secchi-depths) accuracy (declaration of the producer) Shallow water systems : horizontal 0,5 m, vertical 0,1 bis 0,2 m Deep water systems : horizontal 2 m, vertical 0,2 bis 0,3 m Systems are in strong development this time

16. LKN-SH | BSHC Lidar Seminar | Lutz Christiansen | Hannover, 28.05.2014 Area of Laserbathymetry The whole coastline (ca. 640km, ca. 800km²) from the buildungs of coastal protection on the dry land down to 3-5m (1Secchi), Minimum: data until the area of hydrographic survey Baltic Sea
