GIS Studies
GIS Mapping services offer a wide range of capabilities to help businesses and organizations effectively visualize and analyze geospatial data. GIS, or Geographic Information Systems, are computer systems that produce connected visualizations of geospatial data, such as maps, to communicate valuable information that may not be immediately apparent from raw data alone.
One of the most common types of GIS maps is the category map – often color coded. This map allows you to visualize which category each location belongs to. For example, you could use a category map to show site locations approved for renewable energy development in the U.K.
Another type of GIS map is the quantity map, also known as a choropleth map. This map color-codes each feature based on a numerical attribute, such as sales volume. Darker colors indicate higher values, while lighter colors represent lower values. Quantity maps are useful for identifying patterns and trends based on location, and they are commonly used for business analysis and demographics mapping.
Creating rules for quantities is slightly more complex than for categories. We define class breaks, which are ranges of values, to determine the color ramp used in the map. There are different methods for determining class breaks, such as equal interval, quantiles, Jenks optimization, and heads & tails. Each method has its own advantages and is chosen based on the nature of the data being mapped.
GIS mapping also includes other map types, such as bubble maps, heat maps, and cluster maps. These maps provide additional ways to visualize data and gain insights into spatial relationships. GIS maps can be stacked with multiple layers, allowing users to toggle each layer on and off as needed. Additionally, GIS maps offer interactivity, allowing users to pan, zoom, and click on features to access additional information.
