January 2015 Update
Scottish Natural Heritage published Visual Representation of Wind Farms: Good Practice Guidance in March 2006. Revised guidance replacing the 2006 guidance was published in July 2014 as Visual Representation of Wind Farms version 2. This was replaced by version 2.1 published in December 2014 and came into effect immediately.
When version 2 was published, Scottish Natural Heritage recognised that baseline photography was expensive and that it was often captured well in advance of the submission of an Environmental Statement. As a result, they agreed a grace period of 6 months from the publication of version 2 in which visualisations produced under the 2006 guidance could still be submitted. After January 2015 they expect all visualisations to comply with versions 2.1.
