Hi, I'm researching for an application which needs to store "zones" based on gps points. Not sure the shape of these yet, most likely a circle or polygon. The system then needs to determine what zone a particular "location" (gps point) is in.
Can someone give me some direction as far as what terminology I should be learning and using, good beginner tutorials, and/or documentation a ogc/gis newbie should start with? In what I've got out of it so far I'll need to create polygons (or other geometry) and use st_within function do determine if the point is in that geometry. What I don't understand yet is how these polygons get created from lat/long data points. Thanks!
