A formal means of representing and manipulating spatially-referenced information represents a Geospatial data model.
<h3>What is Geospatial data model?</h3>
A formal method of describing geographically referenced data is a geospatial data model. It is a conception of reality and a distilled picture of physical things. Understanding trends that directly relate to your best and worst client bases is made possible by spatial data. You may combine your own consumer data with a tonne of free census and geographic data from open data portals run by government agencies.
Organizations can foresee and get ready for potential changes caused by shifting spatial conditions or location-based events with the aid of geospatial analytics. Decision-makers can better understand why solutions that succeed in one place frequently fail in another by using location-based data.
