Yes, the MinMax elevation and the MaxCulture are datasets published by Terra Vista when publishing the CDB dataset of elevation and GS/GT features respectively. Those datasets are often used by runtime systems to optimize some computations such as LineOfSight.
I'm not sure where to ask this so I try here.
About MinElevation and MaxElevation components, which tool is able to generate such component. Does Terra Vista do it when creating the CDB ?
