I'm trying to convert a lake's bathymetry polygons that are assigned an elevation to contours. I can't just perform a topo to raster and I can't just convert polygons to polylines while maintaining accurate elevation attributes for the desired contour lines. How can I get the contours and have the correct elevation attributes attached?
also... I have a separate time period's bathymetry with contours that I've rasterized. I want to calculate volume. I'm thinking I should do a cut fill between the surface and the bottom. How do I create the raster for just the surface at one elevation level?
