Automatic Generation Cleaning & Generalization of 50 Contours for NRCan's Geospatial Database

Natural Resources Canada (NRCan) has developed a process to automatically generate, clean and integrated contour lines from Canadian Digital Elevation Data (CDED). Part of this workflow is an impressive collection of 25 FME workbenches that have been developed to drastically minimize the need for manual editing. Manual editing has been reduced in some cases from days to one to two hours. We would like to show you some example of those tools.
