Spatial Analysis is the process of manipulating spatial information to extract new information and meaning from spatial data. It is a type of geographical analysis done using a GIS which seeks to explain the patterns and relationships between objects or in an area, to better understand and visualize information and data, bringing a holistic understanding of a given situation.
