Class LandLevel

Namespace

EncDotNet.S100.Renderers.Skia.Scene

Assembly

EncDotNet.S100.Renderers.Skia.dll

One level of detail of the bundled land basemap (issue #731): the land simplified to Tolerance and cut into a GridSize×GridSize grid of LandTiles, so a renderer draws only the tiles in view. Tiles are decoded on first use.

Properties

GridSize

The number of tiles along each side of the world square.

public int GridSize { get; }

Property Value

int

TileSize

The side of one tile, in EPSG:3857 metres.

public double TileSize { get; }

Property Value

double

Tolerance

The simplification tolerance in EPSG:3857 metres: no point of the level's coastline is further than this from the source coastline. 0 for the full-resolution level.

public double Tolerance { get; }

Property Value

double

Methods

GetTiles(double, double, double, double)

The tiles that hold land and intersect the given EPSG:3857 rectangle. Only the single world (±Circumference/2) is covered; a caller that draws adjacent world copies offsets its query rectangle per copy.

public IReadOnlyList<LandTile> GetTiles(double minX, double minY, double maxX, double maxY)

Parameters

minX double

minY double

maxX double

maxY double

Returns

IReadOnlyList<LandTile>
