📸 Aerial Photographs and Satellite Images

Geography exams — especially at OCR B — sometimes provide aerial photographs or satellite images alongside or instead of a map extract. You need to be able to interpret what you see and link it to map evidence.

Two Types of Aerial Photograph

Vertical (bird's eye view): Taken directly overhead, looking straight down. Shows a plan view — the same perspective as a map. Features appear foreshortened but in their true map positions. Easy to measure distances if scale is known. Useful for land use mapping and comparing with OS maps directly.
Oblique (angled view): Taken at an angle, usually from a plane or drone. Shows buildings and vegetation in 3D — you can see height and volume of structures. More visually intuitive but harder to measure distances from. Good for showing the character and texture of a landscape.

What to Look for in Aerial and Satellite Images

What You SeeWhat It Suggests
Dense, regular grid of streets with terraced housingOlder inner-city residential area, likely 19th-century development
Large, regularly spaced buildings with car parksIndustrial estate, retail park, or edge-of-city commercial area
Green fields with irregular shapes and hedgerowsRural farmland — likely pastoral (animal) farming
Regular rectangular green fields with straight boundariesArable (crop) farming, likely mechanised agriculture
Blue/grey water body with white foam lineCoastline — useful for identifying erosion features like cliffs or beaches
Dense green canopy with irregular patchesTropical rainforest or dense woodland
Brown/red land with sparse vegetationSemi-arid or recently deforested area
Pale blue/grey urban sprawl with road networksUrban area expanding into surrounding rural land (urban fringe)

Linking Photograph to Map

Questions often ask you to identify which part of a map corresponds to a photograph, or to describe what a photograph shows using map terminology. The approach is:

  1. Identify distinctive features in the photograph: a river bend, a main road junction, a large building, a reservoir
  2. Find the same features on the map using the OS symbols
  3. Give the grid reference of the matching area on the map
  4. Describe any differences between what the photograph and the map show (a photograph may show recent development that postdates the map)

Satellite imagery (e.g., from Google Earth) is particularly useful for showing change over time — comparing images from different years can reveal deforestation, urban growth, coastal erosion, and flood extent. Exam questions may show two satellite images from different years and ask you to describe the change.
