Using off-the-shelf digital cameras for planning permit detail surveys - a comparison with conventional surveying methods
Conventional methods of detailed feature surveys have progressed somewhat over the years with the introduction of automated measurement and storage along with reflectorless technologies; but are nonetheless an intensive and time-consuming procedure. With the current technological developments in the field of digital cameras and photogrammetric software such as iWitness (by Photometrix), it is now possible even for an inexperienced user to perform a photogrammetric survey, measuring coordinated points of interest on imaged objects. It has become apparent that a useful application may be in the field of detailed feature surveying, particularly for planning permit applications. This paper aims to present an introduction to photogrammetric design, some issues and strategies for field data acquisition and a comparison of this technique to other conventional field acquisition techniques in a pro-con manner. This paper will also present identifying factors to investigate for when this method is and is not an ideal alternative to current survey practises through simple case studies.
