WMTS backgroudLayer with API key #586
Comments

Can you try whether not truncating the URL here [1] works? Possibly the code should also be adapted to remove know query paramters (REQUEST, VERSION, etc) from the URL and keep the others. |
|
I am using qwc-docker, how can I find the file? |
|
You'll need to compile a custom viewer, see https://qwc-services.github.io/master/configuration/ViewerConfiguration/#custom-viewer |

Thank you @manisandro Managed to get it to work by adding function createWMTSSource(options) {
const urls = getWMSURLs(Array.isArray(options.url) ? options.url : [options.url]).map((url) => {
// Initialize the base URL
let updatedUrl = url;
// Append rev parameter if it exists
if (options.rev) {
updatedUrl += `?${options.rev}`; // Start with a question mark for rev
}
// Check if a key is provided and append it to the URL
if (options.key) {
// If rev is present, append key using "&"; otherwise, use "?"
updatedUrl += options.rev ? `&key=${options.key}` : `?key=${options.key}`;
}
return updatedUrl;
});Had an additional issue with the resolutions, as wmts_config_generator.py could not handle the minimum zoom starting from EPSG:3857:7 instead of EPSG:3857:1. Also removed the high zooms that require subscription. {

Can you elaborate on

The Ordnance Survey EPSG:3857 Tile Matrix Set starts at Zoom level 7 and not 0. Attached at the bottom is the relevant snippet from Running: Produces: "resolutions": [

I would like to add UK OS Maps WMTS layer as a background map. However, my request needs to include an API key as documented here.
This is the correct format of the get request that I am trying to achieve
https://api.os.uk/maps/raster/v1/wmts?key=xxxxxx&SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=Light_3857&STYLE=default&FORMAT=image/png&TILEMATRIXSET=EPSG:3857&TILEMATRIX=EPSG:3857:16&TILEROW=21779&TILECOL=32721Instead, I am getting:
https://api.os.uk/maps/raster/v1/wmts?layer=Light_3857&style=default&tilematrixset=EPSG:3857&Service=WMTS&Request=GetTile&Version=1.0.0&Format=image/png&TileMatrix=EPSG:3857:16&TileCol=32721&TileRow=21779Is there a way to add another custom parameter to the request URL?
