How To Downloading WMTS/WMS Layers in GPKG Format

[gokboeruealp]

Hi,

I am able to retrieve maps from online WMTS or WMS servers. However, I need help figuring out how to download these maps, either in full or from a selected area, in GPKG format.

I think there is an example in this video: https://www.youtube.com/watch?v=UgkRhCw-nxc

I tried the following code but did not get the desired result:

wwd.mainScope.launch {
    val contentManager = GpkgContentManager(File(cacheDir, folderPath).absolutePath)
    val ogcLayerFactory = OgcLayerFactory(serviceAddress)
    val layer = ogcLayerFactory.createLayer(layerName)
    wwd.engine.layers.addLayer(layer.apply {
        configureCache(
            contentManager,
            layerName
        )
    })
}

If anyone can provide guidance or suggest a solution for this issue, I would greatly appreciate it. Thank you in advance!

You have configured offline cache i to gpkg, but then you need to call makeLocal method for some specified sector and resolution to start downloading it. By default, it saves everything what the user sees into cache.

thank you for your reply.
my version: 1.5.7

I tried the makeLocal function but I did not get efficient results, what range should I use as resolution value?

Radians per pixel or depre per pixel.
