<div dir="ltr">Hi Regina,<div><br></div><div>We are a Spatial Analytics company which has diversified into developing standard WebApps and tools. PostGres+PostGIS is the only database that we use company-wide, whether the solution involves GIS or not.</div><div><br></div><div>Out Usage of PostGIS is varied, and includes things like:</div><div><br></div><div>1)We have began to love the ability to do spatial Analytics (Overlay, Spatial Join etc) in the Database, instead of doing that in a Desktop GIS. This has given us an ability to have repeatable processes instead of error-prone point and click, Manual processes.</div><div>2)In many of our projects, the client is not GIS-savvy, and the application is not a GIS portal. But Having PostGIS in the backend gives us the ability to develop functionality which users expect, like find the closest store and the like.</div><div>3)We also develop simple, light-weight APIs on a SASS model, which allow our clients to send a query containing the end-user's lat-long, and we can return whether or not they fall in a given polygon (Say service areas of a stores, or areas where discounts are available and so on)</div><div><br></div><div><br></div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><font color="#999999" size="2">Regards,</font><div><font size="2" color="#444444">Devdatta</font></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Nov 1, 2018 at 9:36 AM Regina Obe <<a href="mailto:lr@pcorp.us">lr@pcorp.us</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Would love to go to Australia sometime.
