Plotting bathymetry – contours and depth bands in different coloured layers
I’m assisting a hydrographic surveyor to plan for plotting in AutoCAD. The survey spec has a requirement for a plot of soundings on a 4m x 4m grid with contours, that’s fine and no problem we’ve done this numerous times before, but there’s also a requirement for a plot with the soundings and contours banded in to different colours, eg 0 to 1 will be red layer, 1 to 2 in orange, 2 to 5 in yellow, 5 to 10 in green and so on. Does anyone know of a software package or add on that will sort our file of all points by depth bands into layers? We did this once before by sorting the file points by depth order and creating individual files for each layer but it took ages.
