UNIT 1 Flashcards
Reference Maps
A map helps us to find the shortest route between two places and to avoid getting lost along the way. The maps in an atlas or a smartphone app are especially useful for this purpose.
Thematic Map
A map is often the best means for depicting the distribution of human activities or physical features, as well as for thinking about reasons underlying a distribution.
What’s a Map
A scale model of the real world, made small enough to work with on a desk or computer.
What’s a map maker called?
Cartographer
Choropleth Maps
Displays data by using different colors or shades of colors. Each color or shade shows a different quantity of data
Dot Maps
Shows data by placing points on a map where the data is occurring. Shows spatial situation of data
Graduated Symbol Maps
A graduated symbol map also know as a proportional symbol map is a type of thematic map that uses map symbols that vary in size to represent a quantitative variable. Typically, the size of each symbol is calculated so that its area is mathematically proportional to the variable.
Isoline Maps
Use lines to connect different areas that have similar or equal amounts of data
Weather map (shows areas with similar temperatures)
Cartogram Maps
Shows data in a dynamic way
The greatest value represented by the largest area
Time-distance Decay
Time-distance Decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales’ activity space, their interactions begin to decrease.
Map Projections
The shape of an area can be distorted, so that it appears more elongated or squat than it is in reality.
The distance between two points may become increased or decreased.
The relative size of different areas may be altered, so that one area may appear larger than another on a map while it is in reality smaller.
The direction from one place to another can be distorted.
Geospatial technologies
GIS, Satellite Navigation, and GPS
Allow businesses, people governments, and organizations to locate places and visualize geographic data
Geographic Information Systems (GIS)
Computer system that can collect, analyze, and display geographic data
Captures, stores, queries, and displays the geographic data.
It produces maps that are more accurate and attractive than those drawn by hand.
Remote Sensing
The acquisition of data about Earth’s surface from a Satellite orbiting Earth or from other long-distance methods.
Online Mapping and Visualization
The compilation and publication of Web sites that provide exhaustive graphical and text information in the form of maps and databases. Online mapping services are used for tasks such as planning trips, determining geographical positions, finding landmarks and businesses, obtaining addresses and phone numbers, and plotting storm tracks
Satellite Navigation System
Sat Nav provides geo-spatial positioning
Specific location on or above the earth in 3 dimensions
Locate latitude, longitude, altitude, velocity, and time information
Census Data
Censuses can be conducted at various levels, ranging from national censuses that cover an entire country to regional or local censuses that focus on specific areas or communities. The data collected through a census is often used for statistical analysis, research, and the development of public policies. It is an essential tool for governments, businesses, researchers, and policymakers to make informed decisions and address the needs of the population.
What are geographers interested in?
Exploring why phenomena are found where they are
Looking a how actions at one point on earth can affect conditions elsewhere
Place: A Unique Location
A feature’s place on Earth by identifying its location, the position that something occupies on Earth’s surface. In doing so, they consider three ways to identify location: place name, site, and situation.
Place Names
Because all inhabited places on Earth’s surface—and many uninhabited places—have been named, the most straightforward way to describe a particular location is often by referring to its place name. A toponym is the name given to a place on Earth.
Site
The second way that geographers describe the location of a place is by site, which is the physical character of a place. Important site characteristics include climate, water sources, topography, soil, vegetation, latitude, and elevation. The combination of physical features gives each place a distinctive character.
Situation
Situation is the location of a place relative to other places. Situation is a valuable way to indicate location, for two reasons:
Finding an unfamiliar place. Situation helps us find an unfamiliar place by comparing its location with a familiar one.
Understanding the importance of a place. Situation helps us understand the importance of a location. Many locations are important because they are accessible to other places.
Resource
a substance in the environment that is useful to people, economically and technologically feasible to access, and socially acceptable to use.
Sustainability
the use of Earth’s resources in ways that ensure their availability in the future.
renewable resource
produced in nature more rapidly than it is consumed by humans.
A nonrenewable resource
produced in nature more slowly than it is consumed by humans.
Three Pillars of Sustainability
Environmental Pillar
Society Pillar
Economic Pillar
Environmental Pillar
The sustainable use and management of Earth’s natural resources to meet human needs such as food, medicine, and recreation is conservation.
Society Pillar
Humans need shelter, food, and clothing to survive, so they make use of resources to meet these needs.
Economic Pillar
Natural resources acquire a monetary value through exchange in a marketplace
Sustainability’s Critics
Some environmentally oriented critics have argued that it is too late to discuss sustainability. The World Wildlife Fund (WWF), for example, claims that the world surpassed its sustainable level around 1980.
Others criticize sustainability from the opposite perspective: Human activities have not exceeded Earth’s capacity, they argue, because resource availability has no maximum, and Earth’s resources have no absolute limit because the definition of resources changes drastically and unpredictably over time.
Cultural ecology
The geographic study of human–environment relationships
Environmental Determinism
Physical environment caused social development
Possiblism
To explain the relationships between human activities and the physical environment
The physical environment may limit some human actions but people have the ability to adjust to their environment
Globalization
free trade, transportaion and communication equals a growing economy
