What is Geographic Information System (GIS) Mapping?
A Geographic Information System (GIS) creates, analyses, and maps information that is linked to specific areas. The most common use of GIS is for producing maps that provide insights that may not be obvious from raw data alone.
GIS mapping works by linking location (spatial data) with description information (attribute data). The maps created help improve our understanding of regions and facilitate better decision-making.
Why is GIS Mapping Needed?
GIS mapping serves industries where location-based insights are critical. It helps:
1. Map Where Things Are
Example: Mapping the locations of renewable energy installations (e.g. wind turbines) to determine distance from residential zones.
2. Map Quantities
Example: Visualising areas across farmland with the highest agricultural output to plan investments in irrigation.
3. Map Densities
Example: Mapping population density in Irish cities to prioritise public transport projects.
4. Find What is Inside Areas of Interest
Example: Identifying all properties, roads, and natural features located within a floodplain. This information can be used to calculate potential risks and support protective measures.
5. Find What is Nearby Areas of Interest
Example: Identifying schools, parks, and businesses close to a proposed housing development site to evaluate community impact.
6. Map Change Over Time
Example: Monitoring biodiversity changes over time to assess the impact of agricultural practices.
Who is GIS Mapping Recommended For?
GIS mapping offers insights that drive smarter decisions for many industries. GIS mapping can be particularly beneficial for:
-
Government and Public Sector: Urban planners, local councils, and emergency services.
-
Environmental Agencies: For monitoring ecosystems, biodiversity, and climate change impacts.
-
Real Estate and Construction: To analyse land usage, zoning, and infrastructure planning.
-
Utilities and Energy: For managing networks like power grids, water supply, and telecommunications.
-
Agriculture: Farmers and agri-businesses leveraging GIS for precision farming and land management.
