(19 cards)
spatial humanities
process of including space and place in humanities
spatial humanities example
historical maps
social geography
maping fictional places
mapping in journalism
data maps
Show basic facts like population, weather, or traffic.
Usually made with numbers and are simplified.
Good for giving a big-picture view.
Often miss the details of real life in a place.
deep maps
Show rich, detailed stories about a place.
Include people, buildings, animals, plants, history, and feelings.
Use photos, videos, sounds, and stories — not just numbers.
Focus on qualitative (descriptive) info, not just quantitative (numbers).
Bring narrative (storytelling) back into mapping.
why deep maps matter
They give a richer, more human view of the world.
Do maps tell the truth?
maps are political and may not accurately reflect real life data
what type of maps are data maps
population maps
digital maps
specific set of techniques - different to creating maps by hand
digital maps common formats
raster maps
vector maps
raster maps
grid of pixels
in a data map, each pixel represents something about that point such as roads, weather
vector maps
geographic features represented as series of numerical values
usually points, lines, and polygons
mapping aesthetics to values
how visual elements (like position, size, color, and shape) are used to show information on a map.
mapping aesthetics to values
MAPS vs data maps
maps: position is usually based on
geographic position (i.e. physical location on earth)
data maps: use position, size, color and shape to
draw points on a map, or will use position and colour to
fill in polygons
Polygons
Use position to place the area.
Use color to fill it in and show data values (e.g. income, pollution).
how do we create our own maps
- a basemap: backgroundmap on which to draw data
- geographic elements: points, lines or polygons
- data (quan to be mapped to geographic data
- GIS (geographic info system) software which can interpet and map sets of geographic elements
basemap
needed to anchor geographic data in recognisable space
often provided by third part (google)
geographic data
points: longitutide coordinates
lines: multiple connected sets of points
polygons: joined and closed lines
points coordinates
decial (51, 100)

geographic info ine on column in the format (latitufe, longitude) 51, 10
works on relational tables (tables with connected data)
Keeps geographic info separate from ther data.
This way is more efficient and makes it easier to update the map or data later.
