1 Maps & Graphs!!

2 What is a graph? A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship. OR / AND A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship. OR / AND A pictorial device, such as a pie chart or bar graph, used to illustrate quantitative relationships. Also called chart. OR A pictorial device, such as a pie chart or bar graph, used to illustrate quantitative relationships. Also called chart. OR A diagram showing how two qualities are related A diagram showing how two qualities are related

7 Data terminology Mean Mean Mode Mode Range Range Median Median

8 Data terminology Mean (Average) Mean (Average) approximating the statistical norm or average or expected value Mode Mode is the value that occurs the most frequently in a data set

9 Data terminology Range Range The range of data in the set. i.e. the highest and lowest values in the data set Median Median the middle value of an ordered set of values

12 What is a map? A map is a simplified version of reality and is used to record information about the earths surface. Maps show a birds eye view of an area and is drawn to scale AND A map is a simplified version of reality and is used to record information about the earths surface.

21 What is a choropleth map? A map used to show the average density (or concentration) of features such as population and rainfall A map used to show the average density (or concentration) of features such as population and rainfall

22 What is a choropleth map? Each area that falls within a particular range is allocated an appropriate colour until the overall pattern is revealed. Each area that falls within a particular range is allocated an appropriate colour until the overall pattern is revealed.

23 What is a proportional circle map? A map that uses symbols (shapes – generally circles) drawn in a proportional size of a represented variable. A map that uses symbols (shapes – generally circles) drawn in a proportional size of a represented variable.

24 What is a flowline map? F lowline maps are designed to show movement – most commonly transports systems or flow of people with the use of arrows with the width of the arrow representing the amount.

25 Photographs Ground photos are those taken at ground level with the camera pointed horizontally. Ground photos are those taken at ground level with the camera pointed horizontally. Aerial photos are taken from the air or a high point. They can be: Aerial photos are taken from the air or a high point. They can be: Oblique – an aerial photo taken on an angle Oblique – an aerial photo taken on an angle Vertical – photo taken from a plane with the camera lens pointing straight down Vertical – photo taken from a plane with the camera lens pointing straight down

26 Photographs Satellite images – are taken from space that are digitally captured data of the earths surface which is processed to produced a digital image.

32 What is a topographic map? Topography (topo-, "place", and graphia, "writing") is the study of Earth's surface features Topography (topo-, "place", and graphia, "writing") is the study of Earth's surface features

33 What is a topographic map? Its a map which accurately depicts the physical features and relief (landscape) of an area by using contour lines to represent the size, shape, and elevation of the features. Its a map which accurately depicts the physical features and relief (landscape) of an area by using contour lines to represent the size, shape, and elevation of the features. They are usually maps of fairly small areas such as a town, or city and its surrounding countryside They are usually maps of fairly small areas such as a town, or city and its surrounding countryside

34 Topographic maps show… Natural Features: rivers, vegetation, coasts and relief (hills, plains, plateaus, mountains etc) Natural Features: rivers, vegetation, coasts and relief (hills, plains, plateaus, mountains etc) Cultural Features: roads, railways, bridges, houses Cultural Features: roads, railways, bridges, houses
