Reference maps
general information, navigation, local maps
Reference maps examples
political, physical, and road maps
Political map
states, countries, capitals (reference map)
Physical map
natural features (reference map)
Road map
highways, streets (reference map)
Thematic maps
communicate information about a place, including its spatial aspects and what it is like there.
Choropleth maps
use various colors, shades of one color, or patterns to show the location and distribution of spatial data.
Dot- density
each dot represents a specified quantity of a spatial characteristic
Graduated symbol
Use symbols of different sizes to indicate different amounts of a variable
Cartogram
the sizes of countries are shown according to a specific variable. Area is distorted to show a variable.
Isoline maps
use lines that connect points of equal value to depict variations in the data across space. Used for weather and elevation.
Absolute location
exact and precise, address, latitude and longitude
Relative location
relationship to another place, saying “its next to my house” “between the high school and clemets building”
Absolute distance
exact and precise distance away
Relative distance
“How far is waco from dallas” “Its 1 hour”
Spatial interaction
conections contacts, movement and flow of things between places. Amazon has drastically decreased relative distance between consumers and products.I can order anything on Prime and have it delivered to my house in two days!
Absolute direction
exact and precise directions to location
Relative direction
relative relationships, turn left at target, then right at the second stop-sign
Clustering
close together, density, the number of something in a defined area
disperal/distrubution
far apart from eachother
Patterns and spatial associations
indication that two or more phonemes may be related, associated, or correlated with one another.
Mercator
area is distorted near the poles, increases size of high latitude areas
Peters equal area
shapes are inaccurate near the poles, vertically stretched near the equator
Robinson
all aspects are slightly distorted
Conic map
wrapped around a cone
fieldwork/field observations
the act of an individual physically visiting a location or place and recording firsthand information there
Geospatial technologies purpose
are utilized by businesses, organizations, individuals and government agencies to make decisions.
Geographic information systems
Computer system/software that stores, analyzes, and displays information from multiple digital maps or data sets.
Remote Sensing
The use of cameras or other sensors mounted on aircraft or satellites which orbit the earth above the atmosphere to collect digital images of the earth’s surface. Examples
toponym
locations name, ushally reflective of the culture and history of a place
site
enviormental features of a location, includes climate, water sources, topographs, soil, vegetation, elevation (DESCRIBE IT!!!)
situation
describes a places location in relation to other places surrounding it. Relative location, relationship woth other places, polotical, economic, and cultural context
distance decay
The interaction between two places declines as the distance between the two places increases.
Time-Space Compression
The increasing sense of accessibility and connectivity which seems to bring humans in distance places closer together. smaller time space compression, faster that things travel
enviormental determinism
The belief that climate and landforms are the most powerful forces shaping human behavior and societal/cultural development.
possibilism
Acknowledges the limitations imposed by the natural environment, but focuses on the role of human culture to modify and respond to the environment to better fit human needs.
Small scale maps:
show LARGE area with SMALL amounts of data. Zoomed OUT. BIG # on map.
Large scale maps:
show SMALL area with LARGE amounts of data. Zoomed IN. Small # on map.
Scale of Analysis-
It’s the lens through which geographers view a geographic area to study its relationships with other places and identify meaningful information.
