Give 2 advantages of using ICT in the collection of data
can use a handheld GPS to get accurate location information which can be used to show data linked to specific locations within a GIS  can collect qualitative data using digital cameras which can be used to help explain findings / anomalies
1 of 15
ive 4 disadvantages in the use of ICT in the collection of data
often requires expensive equipment (e.g. data loggers / Global Positioning Systems)  may require specific software to actually make use of the data collected using data loggers etc.  data from the internet may have some bias
2 of 15
Give 3 advantages of GIS
provides ability to show lots of information on one map  information can be linked together to help identify spatial patterns / support analysis of data  more and more people have access to GIS - e.g. i-phones etc.

Give 2 ways in which GIS can be used in society.
GIS is used to provide navigation systems in cars 3. Utility companies use GIS to locate and manage water, drains, gas and electricity supplies.

What is meant by a proportional symbol?
proportional symbol - e.g. proportional circles, are drawn in a proportion that represents the size of the value that is being presented.
5 of 15
Give 2 advantages of proportional symbols
1. Proportional symbol maps are not dependent on the size of the area associated with the variable so all areas have equal visual importance 2. provides a quick visual comparison of a variable between 2 places.
6 of 15
Give one advantage and one disadvantage of using a flow line map
An advantage is that it gives a strong visual impression of both volume of movement and direction of movement between 2 places. However A disadvantage is that parts of the map can get very crowded and make it more difficult to interpret
7 of 15
Give examples of data that could be shown using flow lines.
. Pedestrian flows around a CBD 2. Traffic flows between a settlement and surrounding villages 3. Migration to or from the UK

Describe the difference between a bar graph and a Histogram
Histograms show continuous data and therefore bars are drawn touching each other, whereas bar graphs show discrete data and each bar should have a small gap between them.
9 of 15
Give 3 advantages of using Bar Graphs and also state a disadvantage
Advantages: - can easily compare 2 or 3 data sets - can estimate values from a glance - summarises large data sets in visual form Disadvantages: - can only be used with discrete data

Give examples of human features that you could describe from a map
Relates to man-made features / influenced by humans and may include:  Land-use (i.e. residential, recreation, industrial etc.)  Communications (i.e. roads, railways etc.)  Settlement (inc. site, situation, shape (linear, nucleated etc.))
11 of 15
Give examples of physical features that you could describe from a map.
elates to natural features so may include: relief (shape of land e.g. contour patterns, shape of land e.g. valleys, height above sea level etc.) Drainage (e.g. number of rivers, width, lakes, marsh etc.) Vegetation: woodland, type vegetation
12 of 15
Define the following terms:  Linear Settlement  Nucleated Settlement  Dispersed Settlement
Linear Settlement - where buildings are located either side of a main road Nucleated Settlement - where buildings are grouped together (often at a crossroads or around a village green) Dispersed Settlement - where individual buildings are spread out
13 of 15
What is meant by the situation of a place?
he location of a place in relation to other places (e.g. 2 km northwest of the A428, or located on the south bank of the River Ouse) etc. Remember - P A R C Places (nearby Settlements); Accessibility; Relief (near hills) Communications (near roads)
14 of 15
What is meant by the site of a settlement? What could be included in a description of site?
his refers to the physical characteristics of the place and the land it is built on. SHAWL Slope; Height above sea level; Aspect (way slope faces); Water Supply; Land (e.g. floodplain)
