Find latitude, Longitude (X,Y) from Multi-Geometry in PostGIS

A very warm welcome to this all-embracing tutorial on how to obtain latitude and longitude coordinates of multi-geometries in PostGIS. It is important to acknowledge that, no matter whether you are working with sophisticated spatial databases or with normal geographic points, you have to be aware of how multi-geometries work and how to use them in the further analysis. Here, we shall take you through a step by step process, effectively pointing at each logical stage, so as to enable the user to pick precise (X, Y) coordinates from shapes stored in the PostGIS database.

Multi-geometries and significance of multi-geometries in spatial databases shall be explained to you as a starting point. From there, we will go further and show how to extract latitude&longitude using simple SQL-queries from multi-points, multi-lines and multi-polygons. At the end of this tutorial, you will have the capability to handle multi-geometries using PostGIS hence promoting GIS project effectiveness and reliability. Come, take part and bring out the versatility of your geographic data with this fundamental PostGIS method!
