You can also use modelbuilder to iterate through all the FC's in the FGDB that is then passed on to Recalculate FeatureClassExtent. ... View more

You can use the Set Null (spatial analyst) tool to define areas of "no data". You should do the no data/NULL ing only after you've created both the bathymetry and /terrain DEM rasters. your outputs should all be rasters not shapefiles. You could also merge the bathymetry and terrain DEM rasters but it will be a pain getting the symbology/color ramp to work right. Keeping them separate and just using no color for NULL/no data pixels will be easier by displaying them at the same time but with their own separate color ramps. I would also probably include the lake shoreline as an outline with no FILL color (as a shapefile if you want) so you can give it a distinctive color/width that will allow you to highlight it against the terrain /bathymetry. ...

You could also create 2 sets of "DEM's" one for the land part with an appropriate color scheme for land areas and with the lake areas masked out and converted to NODATA. The second "DEM" (bathymetry) for the lake part also with an appropriate color scheme and with the land areas masked out and converted to NODATA. You would have to make sure though that your lake bathymetry data is using the same datum as your land areas (as in reality the lake shoreline may not be 0m or 0 elevation) and that they are of the same pixel sizes and pixel position so that a snap raster is very useful when you create them. When you load them both into Arcmap (doesn't really matter which one is on top), just make sure to set the symbology for both nodata areas in each DEM as no color. ... View more
