We are using Mapnik, Mapproxy and Openlyer6 for the development of GIS based web solutions. The GIS data from Postgis enabled postgresql DB. We are using EPSG: 32643 Projection and got the Map output but when we tried to add a point on the map that is not displaying. The code is posted here... I have added 2 points inside the map area but nothing displayed.

need to know whether the code is correct or not.
