What is GIS?
A geographic information system (GIS) is a computer-based tool used to analyze and visualize data that contains location information, known as geographic or geospatial data. For example, global population data is connected to a location so it could be visualized in a GIS by creating a map. One of the key strengths of maps is their ability to summarize and display a large amount of geographic data in a visually-appealing way, which makes it much easier to identify any patterns and trends in the data.
GIS has numerous applications in fields that involve environmental work, from natural resource management and conservation to climate change analysis. Many complex environmental problems require a data-informed approach, where GIS can play an important role in finding spatial relationships and visually presenting these results. However, it’s important to note that GIS is only a tool designed for a specific type of data. While GIS and maps are ideal at handling geographic data, alternative tools like spreadsheets and graphs may be much better suited to other types of data like numerical data.
