I'm working toward creating a series of web maps involving relations between Canada and the Asia Pacific. The standard Spherical Mercator projection supported (exclusively it seems) by all major web-mapping frameworks is wildly unsuited to the task due to the extreme distortion in the north.
I really need to be able to use some other projection for this while also still being able to publish the final result as an interactive web map. My understanding is that the support for other projections in web cartography is essentially nil, with the exception of Proj4Leaflet. Working on the front-end only, that of course doesn't help me produce map tiles, and the support for alternative projections in that domain seems to be even slimmer. For example, I tried to create tiles in QGIS with a custom projection set in my map display and it managed to convert everything to Spherical Mercator automatically for the output - no projection options at all.
I'm beginning to wonder if the easiest solution isn't just to define an Oblique Mercator projection suited to my particular region, and then just try to shoehorn it into the framework used to display standard Web Mercator maps.
Is there any better, easier, less hacky way of doing this? Are there any web-mapping frameworks out there that support a reasonable set of alternative projections?
