VectorTileLayerOptions¶

Namespace: ThinkGeo.Core

One layer of a set of vector tiles: where its features come from, what it is called inside the tiles, which of its columns travel with them, and which zoom levels it is cut at. The layer named here is the tile's own - what a style layer's source-layer matches - not a FeatureLayer.

public sealed class VectorTileLayerOptions

Inheritance object → VectorTileLayerOptions

Remarks:

A VectorTileLayerOptions.FeatureSource and a name, the way FeatureSourceVectorTileSource.FeatureSources takes them at runtime, so the same data described the same way can be cut now or cut into an archive. The name is what a style layer's source-layer matches. https://community.thinkgeo.com/t/wms-wfs-feedback-wishes/12476

Properties¶

SourceLayerName¶

Gets the name this layer has inside the tiles.

public string SourceLayerName { get; }

Property Value¶

string

FeatureSource¶

Gets where the features come from.

public FeatureSource FeatureSource { get; }

Property Value¶

FeatureSource

ColumnNames¶

Gets the attribute columns written into the tiles.

public Collection<string> ColumnNames { get; }

Property Value¶

Collection<string>

MinimumZoom¶

Gets or sets the shallowest zoom level this layer is cut at.

public int MinimumZoom { get; set; }

Property Value¶

int

MaximumZoom¶

Gets or sets the deepest zoom level this layer is cut at.

public int MaximumZoom { get; set; }

Property Value¶

int

TileBufferInPixel¶

Gets or sets how far past a tile's edge features are carried, in tile pixels.

public int TileBufferInPixel { get; set; }

Property Value¶

int

Constructors¶

VectorTileLayerOptions(string, FeatureSource, IEnumerable<string>, int, int, int)¶

Initializes one layer of a set of vector tiles.

public VectorTileLayerOptions(string sourceLayerName, FeatureSource featureSource, IEnumerable<string> columnNames, int minimumZoom, int maximumZoom, int tileBufferInPixel)

Parameters¶

sourceLayerName string

        The name this layer has inside the tiles - what a style layer's source-layer
        matches.

featureSource FeatureSource

        Where the features come from. It must already deliver the coordinate system the
        tiles are cut in; set its  when the
        data is stored in another one.

columnNames IEnumerable<string>

        The attribute columns written into the tiles. Anything not named here is dropped,
        so name what the style reads and no more.

minimumZoom int
The shallowest zoom level this layer is cut at.

maximumZoom int
The deepest zoom level this layer is cut at.

tileBufferInPixel int

        How far past a tile's edge features are carried, in the grid's own tile pixels, so a
        feature crossing the edge is not cut off at the seam. 8 by default, the margin tiles cut
        on the fly carry, so an archive and the live tiles of the same data draw the same.
