Geographical Skills: Maps and Data (SACE Stage 2 Geography Geographical Skills and Fieldwork)
“Interpret and apply geographical skills including map reading, graph and statistical interpretation, photograph analysis and spatial technologies to answer geographical questions.”
Geographical skills are the practical tools used to read and analyse spatial information: maps, graphs, statistics, photographs and spatial technologies. Section 1 of the SACE Stage 2 Geography e-exam tests these skills directly, so you must be able to give grid references, calculate distance and gradient, interpret graphs and statistics, analyse images, and read patterns from maps. This dot point is about applying skills accurately under exam conditions.

What this dot point is asking
This dot point underpins the geographical skills tested across the course and, in particular, Section 1 of the external examination. Marks here come from precision and correct technique rather than long writing, so practising the mechanics is essential.
Reading topographic and thematic maps
Topographic maps show relief and features using contour lines, symbols and a grid.
- Grid references: a four-figure reference locates a grid square; a six-figure reference locates a point to within 100 metres, read eastings before northings ("along the corridor, up the stairs").
- Distance: use the linear scale or representative fraction. Measure along the route and convert using the scale, for example a 1:50,000 map means 1 centimetre equals 500 metres.
- Relief and gradient: closely spaced contours mean steep slopes; gradient is the vertical rise divided by the horizontal distance.
- Direction and bearing: give compass direction or a bearing in degrees from north.
- Area, cross-sections and intervisibility: estimate area from grid squares and draw cross-sections from contour values.
Two points on a 1:50,000 map are 4 centimetres apart, so the horizontal distance is 4 times 500 metres, which equals 2000 metres. The contour values show the land rises from 120 metres to 320 metres, a vertical rise of 200 metres. Gradient is rise over run: 200 divided by 2000 equals 0.1, or a slope of 1 in 10. Showing the working like this is exactly what the e-exam rewards.
Interpreting graphs and statistics
Geography uses many graph types, and choosing or reading the right one matters.
- Line graphs for trends over time, such as rainfall or population.
- Bar and compound bar graphs for comparing categories.
- Population pyramids for age and sex structure.
- Climate graphs combining a temperature line and rainfall bars.
- Scatter graphs to show relationships, where a line of best fit reveals correlation.
- Choropleth, isoline, flow and proportional symbol maps for spatial data.
Statistical skills include reading rates and percentages, calculating the mean, median and range, and describing trends precisely with figures rather than vague words.
Analysing photographs and remote imagery
Ground-level, oblique aerial and vertical satellite images each give different views. Skills include describing the foreground, middle ground and background, identifying land cover and land use, comparing images over time to detect change (for example deforestation or urban growth), and linking what is visible to geographical processes.
Using spatial technologies
Geographic Information Systems (GIS) layer spatial data so patterns can be analysed, for example overlaying flood risk, land use and population. Remote sensing from satellites such as Landsat classifies land cover and tracks change. GPS locates field data precisely. The exam expects you to interpret outputs from these technologies, not to build them.
When a question gives you a topographic map and a source such as a graph or photograph together, the marks reward integrating them. Locate the feature on the map with a grid reference, read its character from the photograph, and quantify the relationship from the graph or statistics. For example, you might give the six-figure reference of a ridge, describe its steep relief from the closely spaced contours, confirm the land cover from a supplied image, and then read a rainfall figure from a climate graph for the same area. Combining several sources to build one evidence-based answer is the higher-order skill the e-exam tests, and it is best practised with past papers under timed conditions so the mechanics become automatic.
Do not give vague answers or skip your working in skills questions. Saying a slope is "steep" instead of calculating the gradient, or reversing eastings and northings in a grid reference, loses easy marks. Read eastings first, always show calculations, and quote figures from the map, graph or statistic rather than describing them loosely.
Linking it together
A complete command of geographical skills means giving accurate grid references, calculating distance and gradient from scale and contours, interpreting the full range of graphs and statistics, analysing photographs and imagery for change, and reading outputs from GIS and remote sensing. These are the precise, evidence-based techniques that Section 1 of the SACE Stage 2 Geography examination assesses.
Exam-style questions
Questions in the style of SACE Board exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
SACE 2019-style5 marksRefer to the topographic map COAL RIVER. A tourist hires a bicycle in Richmond (area reference 3568) and plans to cycle along route C322 to point P (grid reference 282734) and along C324 to point Q (grid reference 295625). Compare the geographical features of these routes.Show worked answer →
Five marks for a "compare" answer, so identify features of each route and draw explicit similarities and differences, using map evidence (relief, gradient, distance, land use, settlements).
A high-scoring comparison covers, for both routes:
Relief and gradient: read contour spacing to state which route is steeper or flatter and whether it climbs or descends. Closely spaced contours mean a steeper, harder ride.
Distance: estimate length using the linear scale or grid squares; note which route is longer.
Land use and scenery: compare what each route passes through, for example farmland, bush, river flats or built-up areas.
Features along the way: rivers, bridges, junctions or points of interest.
The key skill is comparative language ("Route C322 is steeper than C324, whereas C324 is longer but flatter"), with grid references and contour evidence cited throughout.
