Cartography

Cartography is the art, science and technology of making maps together with their study as scientific documents and works of art - British Cartographic Society

The conception, the designing and the execution of the map – Robinson

Map process

Reality Cartographer Map (replace reality with symbols) Map reader

Page 4: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

What is a map? Real things

Page 5: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Real things reduced to points, lines, or polygons

Page 6: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Drawn with symbols in different colors

Page 7: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Types of Map Reference

Location and position of features Roads State capitols Time zones

Thematic Single theme, topic, attribute

Population density Temperature variation Pickups per capita

Page 8: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Reference maps show locations

Page 9: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Thematic map show attributes

Page 10: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Colors and labels: Reference or Thematic?

Page 11: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Class or groups based on attribute value

Page 12: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Number of classes Eye sees up to 8

variations of one color Be careful

Page 13: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Classification methods

Equal Interval Equal range, 100-200, 200-300, 300-400 Some groups may not have objects in them

Natural groups Objects with similar values, make a group

Quantile Equal number of objects per group 5 groups, 50 states, 10 states per group

Manual

Break points Define highest number in class Which classification method?

Page 15: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Quantile Add break points Total number divided by number

of classes 58 California counties 5 classes 58/5 = 11 counties per class

Dot maps show density

Page 17: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Graduated symbols, bigger, more

Page 18: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Chart maps, piece size, reflects value

Page 19: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Pie size can be proportional

Hierarchy – Front to Back Map topic should be forward

Page 24: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Which is forward? Land? Water?

Scale and Generalization Raster and digitized outline, very detailed

Page 30: Lecture 5 Map design. Cartography Cartography is the art, science and technology of making maps together with their study as scientific documents and

Scale and Generalization Outline is very detailed with each pier

Scale and Generalization Yellow generalization for smaller scale maps

Scale and Generalization As you zoom out (smaller scale) all that detail

isn’t needed and actually takes longer to draw
