I have an image, When user upload this image in leaflet, I want to divide this big images into tiles, how PostGIS can help me in this, ??
I found a few software which essentially break down images into zoom level and x and y coordinates, so there will be lot of tiles images.
Is there a way I can use PostGIS to break down images into tiles ?
