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:
Designed for people to refer to for general information about places.
Two main types:
Political: Show governmental boundaries of countries, states, and counties, the location of major cities, and usually significant bodies of water.
Physical: Show the natural features of the earth, like mountains, rivers, and deserts.
Thematic Maps:
Used as a communications tool to tell us how human activities are distributed.
Types:
Cartogram: A map in which the size of areas is shown in proportion to the variable being measured.
Choropleth: A thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map.
Dot Density: A map that uses dots to represent the frequency of a variable in a given area.
Isoline: A map with continuous lines joining points of the same value.
Proportional Symbol: A map where the size of the symbol varies in proportion to the intensity of the mapped variable.
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 is inevitable when projecting a 3D surface onto a 2D plane.
Types:
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 distances 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, that can be shown on a map
Geographic Information System (GIS): A computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface.
Geographic Positioning System (GPS): This system uses data from satellites to pinpoint 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 an 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 compromising the ability of 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 and 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
