What is Geospatial Analytics?
It is the process of examining geographic or location-based data to reveal relationships, patterns, and trends among variables that could help organizations make more informed business decisions. More specifically, it involves capturing, storing, retrieving, managing, analysing, and displaying all types of geographically referenced data. At its core, geospatial analytics leverages location data - commonly longitude and latitude coordinates - to better understand people, places, and events in the real world.
Data Integration and Management
One of the key early steps in any successful Geospatial Analytics initiative is properly integrating location data from various sources and managing it in a centralized geospatial database or GIS (geographic information system). This may involve collecting spatial data like maps, images, addresses, postal codes; as well bringing in non-spatial data containing longitude and latitude coordinates from business applications, IoT sensors, social media posts, surveys and more. Organizations then need to clean, validate, standardize, aggregate and structure this mixture of structured and unstructured spatial and aspatial data for downstream analysis.
Visualization and Mapping
With location data organized and accessible, geospatial analytics tools allow visualizing and mapping datasets to gain insights. Maps display relationships between variables by pinpointing data points on an interactive map interface, while spatial visualization techniques help identify trends, outliers and clusters. Basic mapping helps find high and low values across regions, while advanced visualization aids pattern recognition. Maps also assist communicating findings to others by presenting a visual rather than just a statistical perspective.
Spatial analytics require GIS and mapping software with functionality for overlaying multiple data layers, filtering by location attributes, switching basemaps, and exporting publication-quality outcome maps. Popular options include ESRI ArcGIS, QGIS, Mapbox and Google Earth Engine. Simple locations can also be plotted on interactive dashboards in analytics platforms like Tableau, Power BI or IBM Cognos without specialized GIS skills.
Spatial Pattern Analysis
Beyond descriptive mapping, geospatial analytics incorporate a variety of statistical techniques to quantitatively analyze patterns in location-based datasets. Common methods include spatial autocorrelation that reveals features correlated by their positions; hotspot or cluster detection algorithms pinpointing statistically significant high-value areas; proximity analysis examining influence of one feature on another based on distances.
Organizations apply these techniques to problems like site selection, risk analysis, market assessment, infrastructure planning and more. For example, hotspot mapping can help retailers identify optimal new store locations based on existing sales clusters. Analyzing spatial autocorrelation of property values aids urban planners develop more effective housing policies.
Demographic Predictive Modeling
Leveraging the power of location, geospatial models can associate demographic characteristics of small areas with satellite imagery, aerial photos and other geographic factors to generate detailed, hyperlocal population and economic estimates. For example, a model trained on census block group data across major cities can predict attributes like average income, age, family size for any given small area solely based on its spatial context.
Such detailed, high-resolution demographic layers assist in tasks like direct marketing, emergency response planning, and infrastructure development where understanding micro-level variations matters. They can also fill data gaps and help monitor changes at a more granular level than official reporting provides.
Route Optimization and Network Analysis
Analyzing road networks and optimizing routes is another prominent use case for geospatial analytics. Mapping road infrastructure onto GIS datasets facilitates network modeling for applications like shortest path analysis, service area delineation, location-allocation problems and more. Emergency response teams can leverage this to route ambulances efficiently. Field service technicians can optimize delivery logistics. Urban planners gain insights on transportation flows.
Location Analytics for Insights
Leveraging the unique capabilities of geospatial technologies and techniques, analytics on spatial data helps transform static maps into strategic decision tools. Whether for site selection, risk forecasting, market potential analysis or supply chain optimization - incorporating a geographic perspective provides a added context to reveal patterns, relationships and insights previously hidden in traditional datasets. As location data grows increasingly available from diverse sources, the opportunities for data-driven decision making through geospatial analytics will continue to expand across all industries.
