C. Brewer, NationalMapping.us Color contrasts Red roads vs brown contours hard to distinguish – use gray contours All colors lighter than black labels – few halos This is not a road map – do not use whole contrast range on road categories Leave contrast available for update and overlay of operational information –magenta could be used for additions if no magenta symbols Contrasting outlines on point symbols separate from each other and background

90K 24K Multiscale durability: good point overlaps

Halos and casings - Dull greenish brown halo on contour labels - Slightly blue halo on hydro labels - Slightly beige casing on local roads - Slightly gray fill in road shields - Slightly gray drop shadow on populated place names Other labels dark enough to read over content

C. Brewer, NationalMapping.us Geoprocessing for map design Contour cracking for faster drawing Polygon-to-line for dashed lines Dissolve on attribute to join small segments (e.g., roads) Pair layers with version not symbolized for labels with different classes (e.g., flowlines, admin areas, populated places) Flowline upstream drainage area (UDA) calculated for stream tapering Smooth DEM first to create generalized contours and hillshade for terrain
