Geospatial analysis

Definition

Geospatial analysis is the process of collecting, interpreting, and analyzing spatial data to understand patterns and relationships in geographic contexts. This technique is crucial for making informed decisions based on location, as it combines statistical analysis with geographical information systems (GIS) and mapping technologies. By leveraging spatial data, geospatial analysis helps visualize complex information and reveal insights that are vital for various applications, from urban planning to environmental monitoring.
