I would like to build a web-based application using leaflet which will have a flat plane and a simple X,Y coordinate system. Is there an SRID I can use for this? I will be generating my own basemaps based on the coordinates.
If it helps you conceptualize what I am doing just consider the game Zork where you move in an X,Y grid. It is similar except I would like to use Leaflet to create this to allow the user to pan, zoom and load basemaps for the different Z-Indexes.
