Determining the accuracy of historical landscape paintings

Historical landscape paintings are widely used to reconstruct past environments. However, artists did not necessarily fully depict reality, many exercising license to relocate and remould features. This paper applies photogrammetric techniques to the problem of determining the accuracy of artistic depictions of landscapes. Four 19th century paintings of Hobart, Tasmania, Australia by different artists were used to test the methods. The artists varied in their accuracy, with Frankland, the surveyor, being the most accurate, and Glover, the romantic professional artist, being the least accurate. This variation suggests that the use of paintings for historical reconstructions and measurements of historic features should be preceded by an accuracy assessment.
