Presentation Details
TerraLogik was contracted by NAV CANADA to generate a 1:500,000-scale topographic base from 1:50,000-scale data for use in aeronautical navigation charts. TerraLogik used the raster analysis tools in FME, coupled with custom Python code and the GDAL open-source library, to create generalized contours at 1:500,000 scale from 1:50,000-scale DEMs covering Canada and the Northern United States. See how the WorkspaceRunner is used to perform this process - and reduced processing time from 24 hours to 1 hour per chart.
