I need to create a topographic map of an imaginary place. My map has to be on regular printer paper. The map has to include At least 20 contour lines with none crossing, Contour Intervals/Index Lines, Map Legend, Large Hill that has steep and gentle sides with river, Small hill that features a cliff, Depression, at least 3 Water Features w/contour lines, 5 types of buildings/locations.
I need help with understanding what to put on the map first through last. I also would like a more deep understanding of what's needed and what that thing is.
