Spatial analysis is a research area that involves the study of the patterns, relationships, and trends of spatial data. It involves the use of geographic information systems (GIS) and other spatial analysis tools to analyze and visualize data in order to understand spatial relationships and make informed decisions. Spatial analysis can be applied in various fields such as urban planning, environmental science, transportation planning, and public health. It can help researchers identify spatial patterns, analyze spatial relationships, and model spatial phenomena to address complex spatial problems and challenges.
