Maps
Value of maps
As a way of recording and storing information - govmt., business, society at large must store large quantities of information about the environment and natural resource location
As a means of analyzing locational distributions and spatial patterns - maps let us recognize relationships and make it possible for us to visualize and conceptualize patterns and processes that operate through space
As a method of presenting information and communicating findings - Maps allow us to convey information and findings that are difficult to express verbally
Communicating with maps
Equally important to analysis
A map is only as good as the narrative that goes along with it
Alone, can tell an implicit story around a particular issue. Adding a narrative (visual, textual, verbal) elevates the purpose of the map
Cartography is closely related to this concepts - “Map Design” aka color choices, element arrangement (data points, boundaries, overlays, fonts)
Maps are symbolic abstractions - “generalizations” or “representations” of reality
What is the motive? Who will read the map? Where will it be used? What data is available for composing the map? What resources are needed (time, equipment)?
Elements of a Good Map
Issues of generalization, abstraction, and simplification
Information commonly needed for map readers: Necessary (Direction, Legend, Sources, Scale), Contextual (Title, Projection, Date of production), Selective (Lines, locator maps, insets, index)
Balaned elements
Map layouts
Defense for each element
Less is More!!
Map Types
What is a map? At it's most basic, a map is a representation of the world. Reference maps, thematic maps, and dynamic maps
Reference maps deliver locational information to the user. Ex. Topographic map
Thematic maps represent how things are distributed across space. Ex. distribution map
Dynamic maps are changeable or interactive representations of the earth, often requiring user interaction and often digital or web based. Ex. Apple maps
