How do you create a contour line?
Contour lines can be created by attributing each point to the lithic count amounts. Note: Overall contour accuracy depends on how well the data used to create the input raster represents the actual surface. Therefore it is important to evaluate the data and its purpose to avoid accuracy issues in data representation.18 jan. 2021
How do you identify a contour line?
Ever noticed those squiggly lines all over your hiking map? Other than the obvious trails and rivers, these squiggly lines are contour lines.
