PostgreSQL has a geometric data type of "point". The format is listed as (x, y) but I am not sure if the X is to represent latitude or longitude. I have seen different systems that us X for either. Typically, coordinates should be read as lat/long but I have seen the opposite as well. An example in the help docs listed a point coordinate as x= longitude and y=latitude. Can someone clarify what the postgres standard is? What this will come down to is how built-in geospatial functions will interpret the point value.
Well the point data type is just that a point with x, y coordinates. The concept of longitude and latitude are higher order defined other systems that use the point type as a building block, i.e. Postgis. So which help docs did you see the x= longitude and y=latitude statement?
