Alternate Message
NA

Message Type
ERROR

Description
Invalid SGS ZH Sample Ratio. This value is used to control the area used for SGS at ZH locations and it should be between 0 and 1. The area is set to <ratio> X cell_area to sample and generate Z values around a cell corner (the sampled elevations are not used in the hydraulic computations, only for map output).

Suggestions
Ensure the .tgc command "SGS ZH Sample Ratio ==" is set to a value between 0 and 1.
