I'd like for my road-path-smooth elements to show at a lower zoom level than they currently are because my application is for the outdoors and these are more important elements. Is that possible? I can't seem to find out how to adjust this in studio.
If you're talking about displaying layers from the Mapbox Streets tileset, then no, it's probably not possible. The vector tiles are optimised for Mapbox's style (also, confusingly, called Mapbox Streets), and don't contain data that isn't already displayed.
Your need is a common one, but unfortunately the only way to solve it is to find a different set of vector tiles that meets your needs, or create one yourself.

I'm using MapBox's static API in a project. I have managed to load maps with the same width and height in terms of latitude and longitude regardless of the resolution. This is so that users see the same area regardless of their screen resolution, for example. The problem is that on larger resolutions features and —especially, text appear much smaller, relatively. For example, these two maps look very similar, except for the size of text (and some other details, like the thickness of lines):
https://api.mapbox.com/styles/v1/mapbox/outdoors-v11/static/0.63189425,46.195750258333334,14.3/540x285#2x?access_token=ACCESS_TOKEN

Is there a way to compensate for this and have the text on the larger image print larger, and have thicker lines? (in pixel terms). The result being that, say, two 6 inch screens print text in the same real-world size (centimeters) regardless of their pixel count.
I have looked into layers and filters, but it does not seem like there is a straightforward way of achieving this. It looks like maybe designing new maps would be the way to go, but I'm using the default ones and I would not know where to start.
THank you
I'm a bit confused by the premise of your question here. The API's #2x parameter is meant to toggle resolution and should serve exactly the purpose you describe. The reason for different amounts of label information being included in the images you've shared is because you've used different zoom values (13.15 vs. 14.3) and the labels in Mapbox core styles are zoom-dependent, meaning they change based on the zoom value used to generate the map.
With a fixed image width, and no #2x parameter:
/styles/v1/mapbox/outdoors-v11/static/0.63189425,46.195750258333334,14.3/540x285?access_token=ACCESS_TOKEN
yields

⚠️ Disclaimer: I currently work for Mapbox ⚠️
I want to label stations on my map, and I would like to clusterize the stops at different zoom levels to filter them down. So as you zoom out all you get is the start and end, and then finally a single label start->end.
How do I render a text label on a vector tile ?
I could fetch the stations as a geojson and reload on zoom change if there's no easy way to do this with tiles.
Is there a reason you need to encode your data differently per-zoom-level in the tiles or are you mainly concerned with displaying data differently per-zoom-level? If the latter, I would recommend looking for an approach that focuses more on styling the vector tiles you already have rather than trying to generate those tiles in a more complex fashion. You could try using a zoom function to style your data. If you're using Mapbox Studio, you can also set zoom-specific style rules in the Studio UI, which is the route you'll probably want to go if you're using Leaflet (I see the Leaflet tag in your post but it's not entirely clear what your implementation looks like).
If the former, you may need to use a tool like Tippecanoe. This route will likely be a bit more complex, but gives you fine-grained control over how your vector tiles are generated. Keep in mind that once you've created your tiles using Tippecanoe, you'll still need to style them somehow.
I want to create a static google maps image which displays buildings (and buildings only). I looked through the Styled Maps page on static maps stylings, but I couldn't find an option for buildings in particular.
Please note that this should also work in less populated areas, so simply turning the landscape one colour and showing the roads in another does not suffice (like done in this image).
Is there a way to create such a map?
The closest feature for buildings would be the landscape.man_made feature which selects structures built by humans. You can also experiment on other features that may suite your needs such as points of interest.
For features that you want to hide from the map, you can set the style to visibility:off for that specific feature.
Here's an example that changes the stroke color for all man made landscapes and hides all roads:
https://maps.googleapis.com/maps/api/staticmap?size=512x512&zoom=17¢er=Brooklyn&style=feature:landscape.man_made|element:geometry.stroke|color:0xff0000&style=feature:road|visibility:off&key=YOUR_API_KEY
Note that the sample uses the element geometry.stroke which selects only the stroke of the feature's geometry.
Hope this helps!
When should one use a marker instead of a feature layer of points in Mapbox?
Points layers can be updated and styled dynamically using all the styling tools of Mapbox GL JS. Features in points layers can also be clicked, presenting a popup just like with a marker.
Given this, when would one want to use a marker?
As Andrew mentioned there are two sides two this:
Accessibility
Markers are implemented as DOM elements and thus can be included in the tab order and can be given accessibility attributes
Animation
As markers are DOM elements animating them is quite easy with a bit of CSS & JS. You can animate points on a circle layer too, but its much more of a hassle.
Small point count
The number of markers/points you can display at once is somewhat limited by what the DOM can manage. My suggestion is that, if you have more than 500 points to display, you should opt for a circle layer instead of markers (this is a very rough estimates and depends on other parameters as well, animation, point size etc.). Using a circle layer you will hit - depending on the hardware - a limit in the 10s of thounds of points.
I'm using Mapbox GL JS. Is there any way I can style my base layer to look like the Mapbox Light example, but showing only the UK?
I assume I would use Mapbox Studio to build my own base layer, but I can't see any way in Studio to filter by country.
If that's not possible, is there any way I could show labels on the UK only, and show other countries as filled polygons? (As per this unanswered question.)
Unfortunately it is not possible to filter by a certain geography when selecting the data source for a layer. If you're working with Mapbox's tiles, they'll always cover the entire planet.
There is the possibility to restrict the map to a certain (rectangular) bounds, with the map.setMaxBounds method (https://www.mapbox.com/mapbox-gl-js/api/#Map#setMaxBounds). This might work reasonably well since you want to restrict the view to the UK, but might not be suitable depending on the geometry you want to restrict the view to.
As a workaround you could create a dataset and add a polygon that covers the entire planet except for the extent you want to show in your map. Then add this dataset in your style as the top most layer and style it with whatever you'd like the empty space in your map to look like.
The workaround has been also suggested in this SO answer, if you can get maptiles for the UK only (the SO answer gives a link, but for Germany) you can
upload them to Mapbox as a dataset, export it to tilesets, and then
to a map as a layer. Delete all other layers
You have also the possibility to Style a single country in Mapbox
studio ref this tutorial. The other countries are still shown, but you can style your map in a way to highlight UK
There is a option that allows you to show only one country highlighted. But drawback is, you lose all the layers and tile-level details. Here is the link https://www.mapbox.com/videos/how-to/map-a-single-country-in-mapbox-studio/.
But if you want to include the tile details as well as whole world map but in that map only one or two or custom amount of countries highlighted, then, from above link of Natural Earth download the zipped file of ne_10m_admin_0_countries and upload.
Go back to your map style, and instead of making a blank one. Add another layer of ne_10m_admin_0_countries in your current map. Select the country in the filter option (in same way as shown in video). And change its opacity. That's it.
Hope it helps. Have a great day.
