  1. Hi I have some concerns about bathymetry widths calculation. The bathymetry widths calculated by WMS are up to 50% less than the real measurements. The projection seems to be correct and when I use the ruler I get correct values. The TIN resolution is fine and good. Now I am suspicions of the following issues: 1- The storage calculation from TIN is not correct and consequently the layers widths. 2- The TIN map resolution is not fine enough. 3- The projection is not correct or the ruler tool is not correct or the ruler shows the values in a different projection system (i.e The ruler shows the length at meters while the widths are calculated in a different unit).
