Cartography: Communicating Spatial Information Flashcards
What are the 3 types of Cartographic Traditions?
- ) Communication Maps (cholera map)
- ) Storage maps (oldest)(stores geographic info)
- Topography on them
- Longitude and Latitude
- UTM
- Infinite # of info - ) Analysis Tradition
- recent tradtion
When we make maps we include spatial and non-spatial information, what is examples of spatial information and non spatial information?
Spatial: Numbers, addresses, location, statistics, areas and paths
Non-Spatial: Identity/name, Quantity/magnitude, statistics, and category.
Cartography
science of map making.
Cartographic semiotics
- symbols
- Typography
Cartography as Communication
One of the most useful approaches to the study of cartography is to view maps as a form of visual communication. Cartographers seek to make use of viosual resources such as colour, shape and pattern to communicate information about spatial relationships.
Syntax:
How sentences are laid out in order to create grammatical sentences
Semiotics:
Theory of signs
Semantics
Relationship between a sign (or symbol) and what is signifies
Pragmatics
How is the sign used?
maps are
geographical information of geographical phenomenom.
How is cartography different to other forms of visual communication?
Cartographers must pay special attention to coordinate systems, map projections and issues of scale and direction that are in most cases of relatively little concern to other graphic designers or artists.
Some of the most important decisions cartographers make in the process of cartographic design revolve around…
- ) How much to simplify the situation being depicted and
2. ) How to symbolize the relationships being represented.
Types of Maps:
- ) Planimetric Maps
- ) Cadastral Maps
- ) Topographic Maps
- ) Thematic maps
What maps have more specification of location and position?
Thematic has most specification and Planimetric has the least. Topographic has more than cadastral.
Planimetric Map:
A map showing Horizontal variation
Cadastral Map
- map often based on markers (monuments) for the physical description of a specifiec land area.
- Uses longitude and Latitude
- Everything on map referencing towards markers.
Associated with planning. - Has internal frame of reference
Topographic Maps:
- Maps representing elevation change through contour lines, shading or colour.
- Provides an accurate and consistent frame of reference for locating features on the map
- Continous fram of reference
- Topographic maps have external or global frame of reference
- Has a neat line!
Neat Line:
Beginning and end of map space
Topologic Map:
- Maps that maintain accurate spatial relationships but relax the location accuracy of individual features!
ex. ) map of londons underground is a topologic map because they relax on some location accuracy such as the river. Sometimes features will be relaxed so it is easier to read by the viewer.
