UNIT ONE: THINKING GEOGRAPHICALLY
1. Introduction to Maps
Learning Target: Identify types of maps, the types of information presented in maps, and different kinds of spatial patterns and
relationships portrayed in maps.
● Reference maps are designed for people to refer to for general information about places. The two main reference maps are political and
physical
● Thematic Maps are used as a communications tool – tell us how human activities are distributed

Spatial Patterns Represented on a Map
absolute and relative distance
and direction
Clustering: Grouped/bunched
together
Dispersal: appears to be
distributed over a wide area
Elevation: using levels of how high/low
something is located on the land
Map Projections (distortion in shape, size, distance, and direction)
Mercator Map
Shape and directions of
countries are fairly accurate
Greatly distorted toward poles
Robinson Map
Everything is distorted in small
amounts
Goode
Continent sizes are accurately
portrayed
Directions and distant aren’t
accurate
Gall Peters
Shape of countries especially near the
equator are distorted
2. Geographic Data
Learning Target: Identify different methods of geographic data collection.
Geospatial Data: all information including physical features and human activities
Geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on
Earth's surface
GPS stands for Geographic Positioning System: This system uses data from satellites to pin-point a location on earth and help people find
their way to a destination.
Remote sensing: refers to the process of taking pictures of the Earth's surface from satellites (or, earlier, airplanes) to provide a greater
understanding of the Earth's geography over large distances.
● Spatial information can come from written accounts in the form of field observations, media reports, travel narratives, policy
documents, personal interviews, landscape analysis, and photographic interpretation.
3. The Power of Geographic Data
Learning Target: Explain the geographical effects of decisions made using geographical information.
Geospatial Data: all information including physical features and human activities
Census data: an official count of individuals in a population (in the USA, it happens every 10 years)
4. Spatial Concepts
Learning Target: Define major geographic concepts that illustrate spatial relationships.
Absolute location: The precise spot where something is located
Relative Location: where something is in relation to other things
Space: extent of a area and can be in a relative and absolute sense
Place: refers to the specific human and physical characteristics of a location.Distance Decay: a geographical term which describes the effect of distance on cultural or spatial interactions
Time-Space Compression: is the increasing sense of connectivity that seems to be bringing people closer together even though their distances are
the same
Pattern: The geometric or regular arrangement of something in an area
5. Human-Environmental Interaction
Learning Target: Explain how major geographic concepts illustrate spatial relationships.
Sustainability: the goal of the human race reaching equilibrium with the environment; meeting the needs of the present without while also
leaving resources for future generations
Natural Resources: a physical material constituting part of Earth that people need and value
Environmental Determinism: How the physical environment caused (determined) social development
Possibilism: the physical environment may limit some human actions, but people have the ability to adjust to their environment
6. Scales of Analysis
Learning Target: Define scales of analysis used by geographers explain what scales of analysis
reveal
Scale: the relationship between the distance on the ground and the corresponding distance on a
specific map - also a concept describing how "zoomed in" you are while studying a geographic trait
(Global (Globalization), Regional, National, State, and Local)
Scale of Analysis: how zoomed in or out you are when looking at geographic data
7. Regional Analysis
Learning Target: Describe different ways that geographers define regions.
Region: a place larger than a point and smaller than a planet that is grouped together because of a measurable or perceived common
feature
Formal Region: a region that is based quantitative data data (that can be documented or measured) - all government areas are this because
they share a government (Example: Wisconsin)
Functional Region: a region based around a node or focal point - terrestrial radio broadcasts are an example of this (example: Radio station
broadcast area, DC metro)
Vernacular (Perceptual) Region:
