Land Use and Functions (Leaving Cert Geography): Revision Notes
Land Use and Functions
Aerial photographs are powerful tools that allow us to identify and understand different land uses and functions across landscapes. By recognising specific patterns, shapes, colours, and spatial arrangements, we can distinguish between various economic activities and urban functions.
Primary activities
Primary activities involve the direct extraction or use of natural resources and are typically located in rural areas.
Primary activities form the foundation of economic development by extracting raw materials from the natural environment. These activities are most easily identified in aerial photographs due to their distinctive landscape patterns and rural locations.
Agriculture
- Pastoral farming: Appears as green fields or areas where animals graze
- Arable farming: Recognised through freshly ploughed fields (dark brown/black) or yellow fields showing ripening crops
- Agricultural land typically shows regular field patterns divided by hedgerows or walls
Forestry
- Coniferous forests: Display uniform, dark green areas indicating planted state forests
- Native woodlands: Usually appear as irregular patches of mixed vegetation, commonly found within historic parks and protected areas
Renewable energy
- Wind farms: Clearly visible white structures with rotating blades, typically located in rural areas away from housing developments
- Solar panels: Appear as dark, rectangular installations on building rooftops
Horticulture
- Glasshouses: Distinctive rectangular or curved structures used for growing fruits, vegetables, and flowers
- These facilities are typically located near urban areas to provide easier access to markets
Secondary activities
Secondary activities involve manufacturing and processing of raw materials.
Industrial land use
Factories and industrial buildings can be identified by several characteristics:
Identification Example: Recognising Industrial Areas
Step 1: Look for building shape and design
- Flat rooftops and rectangular building shapes
Step 2: Check the location pattern
- Location in industrial estates on town outskirts
Step 3: Examine transport connections
- Good transport connections including roads and rail links
Step 4: Identify supporting infrastructure
- Large car parks and loading areas for goods vehicles
Tertiary activities
Tertiary activities provide services to people and businesses. These are the most diverse category of land uses visible in aerial photographs.
Educational services
Schools, colleges, and universities can be challenging to identify from aerial views. Key identification features include:
- Playing fields or tarmac courts surrounding buildings
- Green flag initiatives visible as gardens or green spaces
- Organised building layouts with multiple structures
Tourism services
Tourist facilities are identified through various recreational infrastructure:
- Tourist offices and information centres
- Hostels and accommodation facilities
- Caravan sites and camping areas
- Golf courses with distinctive fairways and greens
- Historical sites such as castles and heritage buildings
Transport services
Transportation infrastructure includes:
- Road networks of varying sizes
- Railway lines and stations
- Airports with runways and terminals
- Car parks and bus stations
- These create linear patterns across the landscape
Market and retail services
The Central Business District (CBD) is the main commercial heart of a town or city, identifiable by colourful shop fronts and taller buildings concentrated towards the centre.
- Traditional markets and retail areas are located in the CBD
- Shopping centres are typically found on town outskirts, surrounded by extensive parking spaces
- Retail parks show regular patterns of large, rectangular buildings with associated car parks
Port facilities
Harbours and ports are easily identified by their waterside location and specific infrastructure:
- Quays, piers, and jetties extending into water
- Container storage areas
- Cranes and loading equipment
- These features indicate maritime trade and transport functions
Ecclesiastical functions
Religious buildings and associated land uses include:
- Churches and cathedrals with distinctive architectural features
- Graveyards showing regular patterns of headstones
- Often located in central areas of towns and cities
Medical services
Healthcare facilities can be identified through:
- Hospitals with large building complexes
- Clinics and medical centres
- Ambulances parked in organised rows
- These are typically located with good transport access
Protection services
Emergency and security services are visible through:
- Garda stations and police facilities
- Fire stations with distinctive vehicle bays
- These provide essential protective functions for communities
Residential land use
There are five main types of housing that can be distinguished from aerial photographs:
Residential patterns reflect different periods of urban development and planning policies. Understanding these patterns helps identify the age and character of different neighbourhoods.
- Detached houses: Stand alone buildings separated from neighbouring properties by hedges or gardens
- Semi-detached houses: Two houses joined together, typically found in housing estates
- Terraced houses: Multiple houses joined in continuous rows, usually located on streets close to town centres or in older housing developments
- Apartments: Multi-storey buildings divided into multiple residential units, often featuring balconies
- Bungalows: Single-storey houses, typically located on the outskirts of urban areas
Each housing type reflects different periods of development and planning policies, creating distinct patterns visible from above.
Recreational land use
Recreational areas serve community leisure and social needs:
- Parks showing green spaces with paths and facilities
- Sports fields with marked pitches and courts
- Walking and cycling routes
- These areas provide important quality of life benefits for residents
Traffic management
Understanding traffic patterns and management strategies is crucial when analysing urban areas from aerial photographs.
Congestion hotspots
Congestion hotspots are areas particularly prone to traffic delays and bottlenecks that can be identified through specific landscape features and infrastructure patterns.
Traffic congestion is likely to occur in several key locations:
- Narrow streets that restrict vehicle flow
- Crossroads and junctions where multiple streets meet
- Main shopping areas with high pedestrian and vehicle activity
- Near schools during drop-off and pick-up times
- Bridge approaches and river crossings
Reducing traffic congestion
Various traffic management measures are visible from aerial photographs:
- Pedestrianised streets: Shopping areas where vehicles are excluded to reduce congestion
- One-way systems: Help improve traffic flow on narrow streets
- Roundabouts: Allow more constant traffic flow compared to traditional junctions
- Ring roads and bypasses: Divert traffic around town centres
- Yellow box junctions: Prevent vehicles from blocking intersections
- Off-street parking: Reduces street-side parking that narrows roads
- Double yellow lines: Prevent parking on streets to maintain traffic flow
Future economic development
When planning new developments, three key factors must be considered: site characteristics, transport accessibility, and environmental impact.
Site considerations
Greenfield sites offer several advantages:
Greenfield sites represent undeveloped land, typically agricultural areas that are being considered for new construction projects. These sites offer unique advantages for developers and communities.
- Cheaper and easier to build on flat land
- Located on town outskirts, allowing for future expansion
- Space for essential services like parking and loading areas
- Originally agricultural or unused land that has been rezoned for development
Brownfield sites present different challenges and opportunities:
- Contain old buildings that have become vacant
- More expensive to purchase and redevelop
- Often located in areas with excellent market access
- Require remediation but can revitalise urban areas
Transport accessibility
New developments require excellent transport connections:
Good transport accessibility is essential for economic success. Businesses need efficient ways to move goods and people, while residents require convenient access to employment and services.
- Access to roads and motorways for goods and people movement
- Railway connections for efficient transport
- Proximity to ports and airports for international trade
- Good transport links reduce costs and improve business efficiency
When locating schools, it's essential to choose sites away from busy roads to ensure student safety during road crossings.
Environmental considerations
Environmental protection is crucial in development planning:
- New developments must avoid parks, historic sites, and other preserved areas
- Factories should not be located too close to residential areas due to noise pollution
- Avoid building in areas with existing traffic congestion problems
- Maintain green spaces and environmental corridors
Key Points to Remember:
- Aerial photographs allow us to identify land uses through patterns, shapes, colours, and spatial relationships
- Economic activities are classified into primary (resource extraction), secondary (manufacturing), and tertiary (services) sectors
- The CBD is the main commercial centre, identifiable by shop fronts and taller buildings
- Traffic congestion occurs at narrow streets, junctions, shopping areas, and schools
- Greenfield sites are easier to develop, while brownfield sites offer better market access
- Site selection must consider transport links and environmental protection
