Shading is a process used in drawing for depicting levels of darkness on paper by applying media more densely or with a darker shade for darker areas, and less densely or with a lighter shade for lighter areas.
shading
[graphics (map display)] Graphic patterns such as cross hatching, lines, or color or grayscale tones that distinguish one area from another on a map.
Shading Sets the style of shading used for the surface.
Gouraud Draws the surfaces with a smooth shading to blend individual cell colors together.
hillshading
Shadows drawn on a map to simulate the effect of the sun's rays over the varied terrain of the land. Referenced by: ArcGIS Geostatistical Analyst; Hachure map; SAGA GIS.

Hillshading helps when the software can adjust the lightness of the map according to the hillshade value. Most raster-based GISes will do this.
Hill shading - A method of portraying topography on a map by shading different locations with tonal differences (i.e. different levels of gray) according to illumination by an assumed light source from the northwest, ...
Relief Shading (or Hill Shading)
This technique was created to give a flat map a 3D visual impression. It is designed to simulate the effect of the shadow cast by relief features such as mountains, ranges and gorges.

Do you see how shading makes a big difference in the appearance of surface models? Shading is what allows the eye to interpret a surface as a 3-dimensional object.

relief shading Technique for making hypsography on a map appear three dimensional by the use of graded shadow effects. Generally, the features are shaded as though illuminated from the northwest.
The technique of shading areas on a map with a given pattern of lines or symbols.
Cross-section
A section taken at right angles to the direction of a proposed centerline.
The reference area on a map that lists and explains the colors, symbols, line patterns, shadings, and annotation used on the map. The legend often includes the scale, origin, orientation, and other map information.

Map makers create this effect by using gray-tone shading that tricks the mind into perceiving the impression of undulating topography. In this image, as in aerial photographs, the same effect is produced by variations in surface illumination.
Digital maps derived through spatial modeling are inherently different from traditional analog maps, composed of inked lines, shading and graphic symbols used to identify the precise placement of physical features.
This includes base map information, graphics, text, shading, and other geographic and graphic data required to create the final hardcopy FIRM product to FEMA standards and specifications.
Short lines used for shading and denoting surfaces in relief (as in map drawing) in the direction of greatest slope. The thickness and spacing of the lines indicate the amount of relief.
Today, graphic display techniques such as shading based on altitude in a GIS can make relationships among map elements visible, heightening one's ability to extract and analyze information.
You should now have a "flat" map with no shading like the one shown in the first two figures to the right. Use the zoom tool to position the map correctly on the screen.
Pen plotters can handle most plotting jobs, but they do not produce good results in area shading such as in the production of cholorpleth maps. Raster plotters, on the other hand, are excellent in producing shading results.
A descriptive map that indicates, through some form of shading or pattern, the magnitude of a particular phenomenon within a defined geographical area.
LEGEND
A part of a map which contains explanation of the symbols, colours, and shading that have been used to code the various elements and data values.
You can adjust a variety of visual effects through the three-dimensional effects toolbar such as applying transparencies, layer face culling, layer lighting, shading, and depth priorities.

During the summer dark green shading (dew points in the 60s or higher) indicate humid air. Dew points in the 40s or lower (light green, yellow or white) are considered dry.

Another method of showing topography is relief shading, an artistic impression of elevation, which creates a 3-dimensional view. The addition of colour between selected contour intervals also serves to highlight elevation or depth.

raster based GIS software, numerical values are often used to indicate classes. Reclassification is an attribute generalization technique. Typically this function makes use of polygon patterning techniques such as crosshatching and/or color shading ...
Shaded relief (hill-shading) The technique of relief depiction by using a continuous range of gray shades to show a landscape as if it were illuminated by a light source from a northwest direction.
