Is it possible to tell Leaflet to ask for base layers before getting overlays, from a GeoServer?
The reason I ask is because a Leaflet map of mine is quite slow, and get about 704 PNG-images back from a Geoserver after panning the map, which takes about 1-6 seconds to finish. If the base layer would show up first, it would not looks so bad - at least it would not show grey background areas.
It is common that WMS-layers take about 2-5 seconds to load when moving the screen? How do you handle that problem?
EDIT
The slowness happen when I click on a layer group that have about 20 layers, and it returns about 704 requests with PNG-images that have a size about 2 KB.
My internet speed is about 90 mbit/s.

I have already done Generate XYZ Tiles with layout png format using QGis only zoom level 14 in 10 days.
All image already done 100% thats showup on QGis percentage, but some images become blank or black image.
maybe it was fail when render like bad connection or anything else.
Can i render specific image only that blank image but not 1 by 1.
I dont want wasting time 10 days anymore.
Last i trying another application similiar on zoom 13 with Maperative
But the result is same.
Seems like you have got trouble with your connection or bandwidth osm same like me.
The only solution is download manually, one by one, from the official site, each image.

Save that image on your folder z x y structure in your blank tiles.
I'm using mapbox studio to customize a map and I haven't found the way to display building-outline layer at any zoom level.
If I'm under of 16 zoom level, this layer disappears... even if I force opacity to 1.
Any idea ?
Thank you in advance
The minimum zoom level for the buildings layer in the current tileset (Mapbox Streets v8) is 13.
This means that if you zoom out further (from 12 to 0) the buildings layer will not be rendered on the map.
See documentation:
https://docs.mapbox.com/vector-tiles/reference/mapbox-streets-v8/#layer-reference
The reason for this restriction is that if you requested your browser to fetch and render every building polygon in a wider area (like an entire city or country), this would be more than a reasonable amount of data to render.
If you have your own buildings polygon data and you create a tileset from that, you could choose to include your data across more zoom levels. However, you might waste a lot of computing resources drawing shapes that are too tiny to understand at those further zoom levels.
I am using Mapbox studio.
I use the default OSM road data.
If I zoom in at level 10 I only see major roads.
At zoom level 11 then suddenly lots of smaller roads appear.
I would like to show these roads at a later zoom level. I want to move everything one zoom level behind, so the small roads would show up at level 12.
How can I do that? I can not figure it out.
Thank you
You can change the layers' zoom extent. select or filter layers and move the "Select data" tab on the styling pannel.
Then, swipe the Min slider.
Does unity have any limits when it comes to .tmx files? I am creating a .tmx map on tiled and each tile is 16x16 pixels. I am making a game and I would like to make it fairly universal and make sure most graphics cards can handle it but I'm not sure whether I should divide my map in to chunks that will load when the boarder is crossed or just load the whole map, as I'm not sure if I would be able to program the game to only load say a 50x50 texture and render more of the map as the player moves. So does unity have a maximum number of tiles it can render? Thanks in advance
Open statistics window and see performance stats of your game. Mostly and basicly, Draw Calls is defined your game's parformance. For example FPS decreases under 60 for more than 2500 draw calls on most of PCs.
Assume that your map is 128x128, if you use 16x16 tiles you need 64 nodes otherwise if you use 32x32 tiles you need 16 nodes. More nodes means more loading.
Just check stats and get visuals under control for better performance.
When I zoom in far enough on my map, the TileLayer disappears and I see a bunch of tiles that say "Map data not yet available". I believe these tiles may be coming from the provider, but I am not sure (I am using ESRI WorldImagery dataset).
Is there any way to, at a certain zoom level, just force the tiles to stretch, instead of requesting the tiles for that zoom level? I am ok with some blur, but I do need to zoom in further.
I tried playing around with the zoomOffset option, but whenever I put something there other than 0, my tiles just never load (all grey).
Thanks!
This can be solved by using two of the options of L.TileLayer.
First, set maxNativeZoom to the highest zoom level your tiles provide (the last zoom level before the "Map data not available" starts to appear - this tells Leaflet to stop requesting new tiles when zooming in beyond this level; stretched tiles will be used instead.
Second, set maxZoom to whatever zoom is appropriate; you might not want this to be more than a couple of levels higher than maxNativeZoom, since the stretched tiles will start to look pretty horrible.
You can find out more about the details by checking under "Options" in the documentation for L.TileLayer: http://leafletjs.com/reference.html#tilelayer
