Figure 3.20 Inset maps that enlarge an area of the main map are tied to the main map in
various ways. In this example the inset map is connected to its corresponding portion of the
main map via a bounding box and rays.
Style
The inset map element should include its own scale bar, especially if it is a detail
map. The overview style insets do not necessarily require a scale bar if enough spatial
context is provided for the audience to orient themselves.
Descriptive Text
Descriptive text refers to any text that furthers the map’s purpose that does not fit
into any of the above categories. Often, the specific nature of your map will require
unique descriptive elements. A confident and skilled GIS professional will recognize
when and where a unique text element will enhance the viewer’s understanding of the
map and include it even though it is not referred to in any textbook on cartography or,
indeed, on any other maps the professional has seen. For example, a handout map of
ski trails might list Web sites to go to for current slope conditions.
Style
On a large poster‑sized layout please remember to ensure the readability of all large
blocks of text. This means that the font size must be large enough to read (14 point
or 16 point at least) at a distance of 1 or 2 feet (see Chapter 4, “Fonts,” for more text
size guidelines). You should also double‑space the lines to make it even easier to
read, look less dense, and be therefore less off‑putting. Headings for large blocks
of text should avoid the use of common terms like “introduction” or “study area”
and instead use a description that is pertinent to the material such as “Tide Levels”
or “The Great Lakes.” This ensures that you do not waste one ounce of space on a
