Definition
Geospatial analysis is a comprehensive terminology that encompasses various forms of analyses involving data that has geographical or spatial aspect. The primary focus of geospatial analysis is to use statistical methodology to better comprehend patterns, relationships, and trends within data as pertains location and geography. It is the equivalent of statistical analysis in the field of geography.
What is Geospatial Analysis?
Geospatial analysis involves gathering, displaying, and manipulating GIS (Geographic Information System) data including geographic and satellite imagery. At its core, it involves the creation and application of statistical analyses that result in geographically-based predictions, trends, and patterns. It leverages spatial data and uses spatial theory to add valuable context to visualisations and analyses.
Geospatial analysis is used in a range of industries and sectors, including environmental monitoring, urban planning, logistics, defence, and marketing. For example, a geospatial analysis can show where areas of high crime are likely to occur, aiding police in resource allocation. Another application could be showing how a disease might spread, helping public health officials prepare and respond more efficiently.
