I have a forecast map of 6x6 lat/lon extend from 104E-110E, 10N-16N as an static PNG image and want to make it an overlay on the basemap of OSM/Google map using openlayers 3. The problem is OSM uses Mercator project while my images uses Equirectangular and the maps don't fit.
You can see my implementation at http://thoitiet.hus.vnu.edu.vn/?m=meteo&a=ol
Maybe there are methods where I can transform the image to Mercator first, but it's much better if openlayers can handle the correct projection. How/Is it possible that can I do it?
