Summary
The report examines the integration of aerial photography with GIS. The report focuses on Te Puru in the Firth of Thames. Aerial photography was used to map shoreline change over 35 years over a one kilometre stretch of coastline. Fourth order survey points were used to determine control points for registration of the aerial photographs. Shorelines were digitised from stereo images to identify the toe of the bank (rather than edge of vegetation). The data indicated that the shoreline location is subject to small and non-systematic fluctuations. Purpose: This report is based on a University of Waikato (Department of Geography) project, which was also supported by the Waikato Regional Council in 1993. The aim was to determine whether geographic display and analysis could be used to monitor changes within coastal environments.
Content
Five sequential aerial photographs were analysed, from 1944, 1968, 1983, 1985 and 1991. The 1944 photograph was omitted from the planimetric mapping. Maps are included that show shoreline change 1968-1983, 1983-1985 and 1985-1991.
