PotentialHazardValue
CodeList:PotentialHazardValue
This attribute indicates that part or all of the RouteLink passes through an area that may pose an impediment to passage for users or a level of risk.
Only RouteLink features with the descriptiveTerm of ‘No Physical Manifestation’ or ‘Path’ are eligible to have the potentialHazard attribute populated. Values may be multiple if appropriate.
This attribute is particularly relevant where a RouteLink feature has been provided with a descriptiveTerm of ‘Route Without Physical Manifestation’, as some legal rights of way may pass over problematic or even dangerous terrain and may need to be excluded from any route options.
For all other navigableLink features, this value is null.
