GIS and comparing a UK area with a wider world region

Digital maps let you stack data — flood risk over houses, income over postcodes, deforestation over time. In this lesson you learn how GIS layers work, then use the idea to compare a UK area with a region beyond Europe.

Part of your national curriculum
  • Geographical skills and fieldwork: Use geographical information systems (GIS) to view, analyse and interpret places and data

Key words

Words you'll need today

GIS
Geographical information system: software that stores and maps layered data.
Layer
One set of mapped information, such as rivers, roads or population.
Choropleth
A map shading areas by value, such as income or population density.
Query
Asking the data a question, such as which schools lie in a flood zone.
Time series
The same layer at different dates, showing change.

Layers and queries

GIS stores each type of information as a separate layer tied to real coordinates: one for rivers, one for buildings, one for flood risk. Because the layers share a coordinate system you can stack them and ask spatial questions — how many homes lie within a flood zone, which neighbourhoods are more than a kilometre from a GP surgery. That combination of map and query is what makes GIS more powerful than a paper map.

Choosing the right map type

A choropleth shades areas by value and is right for rates and densities, but it can mislead when areas differ hugely in size. Proportional symbols suit totals such as city populations. Dot maps suit distributions. Flow lines suit movement, such as migration or trade. Choosing the wrong map type is a common reason data looks confusing rather than clear.

Learn

Comparing with evidence

Compare a UK area — say the Lake District or inner Birmingham — with a region beyond Europe such as the Amazon basin or the Sahel, and use the same categories for both: relief and climate, land use, population, employment, and the main challenge each faces. Use figures from the layers, and write comparative sentences: 'X is denser than Y, at ... compared with ...'. That structure earns comparison marks.

Change over time

Time-series satellite layers show change directly: forest lost year by year, a city's edge advancing, a reservoir shrinking in drought. State what changed, where, by how much and over what period, then explain the process behind it. That final step — moving from description to explanation, and being honest about what the data cannot tell you — is what turns a data exercise into geography.

Common mix-ups

Things people often get wrong

  • GIS is just an online map — it stores queryable data layers, not only images.
  • A choropleth is always the best map — it distorts when areas are very unequal in size.
  • Comparing means describing each place in turn — comparison needs linked sentences using both places.

Your written work for this lesson

This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.

Case study

Flooding on the River Calder

The town of Harbrook sits where a steep valley opens onto a flat floodplain. In December 2015, 120 mm of rain fell in 36 hours onto ground that was already saturated. The river rose 2.4 m in five hours, and 380 homes and 54 businesses flooded. Two roads and the railway closed for eleven days.

Geographers pointed to physical causes — steep slopes, impermeable rock, heavy rainfall — and human causes: moorland drained upstream, new housing built on the floodplain, and drains designed for smaller storms.

Since then the town has planted 40 hectares of woodland upstream, built leaky dams in small streams, and raised flood walls to 1.8 m. In the storm of 2020 the peak river level was 0.3 m lower and 40 homes flooded, not 380.

Written for Good Learning Co.

Reading questions

  1. List two physical and two human causes of the 2015 flood.
  2. Explain how planting woodland upstream lowers the river's peak level.
  3. Using the figures, judge how successful the scheme has been. Quote data in your answer.
