Vestfold Hills Lake Bathymetry - Yearly Changes
Progress Code: completed Statement: Data may be held several times for the same lake and to record changes by year. The data set was derived from numerous hardcopy maps, which involved four main processes. These were: 1, The hard copy maps were scanned and saved as TIF images. These images were then...

The data set was derived from numerous hardcopy maps, which involved four main processes. These were: 1, The hard copy maps were scanned and saved as TIF images. These images were then loaded into Corel Trace and the lines traced creating a DXF file. The DXF files were checked using Microstation for small tracing errors such as dangle arcs, and corrected where necessary. 2, The images of the hard copy maps were geo-referenced using Microstation and a similarity transformation. The images were fitted to the Vestfold Hills lake edge data using a visual best-fit approach with varying results. 3, Using the geo-referenced images, the DXF files were imported, and a similarity transformation was performed to fit the line data to the geo-referenced image. Once geo-referenced, all contour lines had their respective heights tagged. 4, The contour line data were then imported into the Arc/Info coverage format (utilising regions) and structured to conform with the Australian Antarctic Division's Spatial Data Model.
