Wcs100ElevationTileSource

class Wcs100ElevationTileSource(val serviceAddress: String, val coverageName: String, val outputFormat: String, val tileMatrixSet: TileMatrixSet, val coordinateSystem: String = "EPSG:4326", headers: Map<String, String> = emptyMap(), connectTimeoutMs: Long = 5.seconds.inWholeMilliseconds, requestTimeoutMs: Long = 30.seconds.inWholeMilliseconds, clientConfig: HttpClientConfig<*>.() -> Unit = {}) : HttpTileSource

HttpTileSource for OGC Web Coverage Service (WCS) 1.0.0 elevation endpoints. Mirrors the URL convention used by Wcs100ElevationSourceFactory — same BBOX-keyed GetCoverage request — but emits raw elevation tile bytes that the cache decorator can persist through a earth.worldwind.layer.cache.TileStore.

(z, x, y): z indexes TileMatrixSet.entries; y is top-down (earth.worldwind.geom.TileMatrix.tileSector already uses top-down row indexing, matching the slippy-map y convention this contract requires).

Functions

open override fun close()

Release any resources held by the source (HTTP client, etc.). Idempotent default no-op.

fetchTile

open suspend override fun fetchTile(z: Int, x: Int, y: Int, previousEtag: String? = null, previousLastModified: String? = null): TileBlob?

launchBulkRetrieval

fun TileSource.launchBulkRetrieval(levelSet: LevelSet, sector: Sector, resolution: ClosedRange<Angle>, scope: CoroutineScope = GlobalScope, maxRetries: Int = 3, retryTimeoutShort: Duration = 5.seconds, retryTimeoutLong: Duration = 15.seconds, onProgress: (downloaded: Long, skipped: Long, total: Long) -> Unit? = null): Job

Download every tile that intersects sector across every level whose resolution falls in resolution — typically used by "save a region for offline use" flows. Returns the launched Job so the caller can cancel mid-download.

tryReadCachedTile

open suspend fun tryReadCachedTile(z: Int, x: Int, y: Int): TileBlob?

Cache-only fast-path read for (z, x, y). Default returns null — a plain network source has no cache to consult. Cache-backed sources override to read their store without going through the network-fetch concurrency budget.
