Function bufferEnvelope

  • bufferEnvelope(x, y, distance, spatialReference?): SpatialFilter

  • Create an axis-aligned envelope spatial filter centered on a point.

    This is a planar expansion in the input coordinate system's units. It is an envelope approximation, not a circular, geodesic, or topological geometry buffer. Use buffer from @honua/sdk-js/geometry when a true geometry buffer is required.

    Parameters

    • x: number

      Center x coordinate

    • y: number

      Center y coordinate

    • distance: number

      Half-width of the envelope in coordinate units

    • OptionalspatialReference: HonuaSpatialReference

      Optional spatial reference

    Returns SpatialFilter

    Example

    // 0.5-degree bounding box around a point
    const req: QueryFeaturesRequest = {
      serviceId: "svc", layerId: 0,
      ...bufferEnvelope(-118.24, 34.05, 0.5),
    };
