I have some static USA maps in Lambert Conformal projection that I would like to overlay in Leaflet together with geo-reference support. They are centered at 38N, 98W. I have found that the closest CRS equivalent is ESRI:102004 from http://epsg.io/102004
+proj=lcc +lat_1=33 +lat_2=45 +lat_0=39 +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m no_defs
So I modified this definition to +proj=lcc +lat_1=30 +lat_2=50 +lat_0=38 +lon_0=-98, and was able to set up this custom projection in Leaflet using proj4leaflet. Now, it is time for me to overlay the static USA maps using L.Proj.ImageOverlay. In order to do that, I need to specify the bounds for the overlay using projected map coordinates. I could open up http://epsg.io/transform#s_srs=102004&t_srs=102004 and get the coordinates there. However, those coordinates are valid only for the +lat_0=39 +lon_0=-96. So how should I determine the correct coordinates based on +lat_0=38 +lon_0=-98 instead?
