The IS_VALID_LOCATION function takes a single GPS location parameter and returns true or false based on whether or not the value of the parameter is a valid location value. If this parameter is a GPS location property type, the definition of that property’s precision attributes will be used as a part of determining the parameters validity. Empty location values are always invalid.
