Our Outreach Officer and Geoscience expert, Dr. Pippa Cowles, explains everything you need to know about GIS for GIS Day.
Today is GIS Day, GIS I hear you say what is that? You may have heard of it in your geography class before. GIS stands for Geographic Information System and connects geography with data – lots and lots of data! It helps us understand what belongs where and looks at data connected to a particular location.
Data can be anything from maps, aerial photos, satellite imagery to spreadsheets. GIS allows all these data types to be laid on top of one another on a single map. It uses location as the common point to relate all these data set together.
GIS can help supermarkets plan where to open a new store, help the police analyse crime patterns, or help aid vehicles get to a location using the fastest route.
GIS lets us create, manage and analyse geospatial data and visualise the results on a map to help us make more informed decisions.
