I've thought for a while that your Gaia Topo layer could be improved, especially because until now I don't think you had any hillshade at all for a topo map! I spent some time checking out your map this morning, and it looks really nice at low zooms, but I'm still a little disappointed at high zooms. At zoom 13 the hillshading ends! For example, at zoom 14, I still much prefer a map with a hillshade (my own work): https://www.gaiagps.com/map/?loc=14.0/-121.1500/48.1582&layer=GaiaTopoRasterFeet https://www.gaiagps.com/map/?loc=14.0/-121.1500/48.1582&laye... https://nst.guide/#14/48.1582/-121.15 https://nst.guide/#14/48.1582/-121.15

That's fair... we chose to drop the shading at that zoom, but we could be wrong. I think some people prefer a cleaner read when zoomed in so far (especially for field use), and shading also makes the tiles larger/slower to download. Gaia GPS does have a separate raster hill-shading layer from ESRI you could layer on top, and we've been considering making our own (we already have an elevation data pipeline and create contour lines, so hill-shading isn't a huge step). Maybe that would have a special UX where you could choose to include it or not in your downloads. I dig your map style!

  That's true regarding file size. It is nice to have the option to overlay another hillshading layer. I use Terrain RGB tiles that I [make myself](https://github.com/nst-guide/terrain#terrain-rgb https://github.com/nst-guide/terrain#terrain-rgb), and having elevation data on the client opens up cool future possibilities like client-side viewshed analysis. And thanks! The [style](https://github.com/nst-guide/osm-liberty-topo https://github.com/nst-guide/osm-liberty-topo) and the rest of this project is open source. The style is a fork of osm-liberty, using the OpenMapTiles schema.
