Interface TypedCoverage

Method Details

• empty

  static TypedCoverage empty(Type type)

  Returns:

  an empty TypedCoverage with the given type

• getType

  Type getType()

  Returns:

  type of values returned by evaluate(org.locationtech.jts.geom.Point)

• evaluate

  Object evaluate(org.locationtech.jts.geom.Point point)

  Get values from coverage at point. Values will be in the type returned by getType()

  Parameters:

  point - to sample coverages at

  Returns:

  result as expected type

• getEvaluateIntersectionOp

  default Optional<Function<org.locationtech.jts.geom.Geometry,List<Pair<org.locationtech.jts.geom.Geometry,Object>>>> getEvaluateIntersectionOp()

  Returns:

  a function that can be used for calculating all the parts of the a geometry that intersect with this grid. The function is 'curried' so that it always applies to this TypedCoverage.

  How the intersection is done is up to each implementation of TypedCoverage, but in general, this method should return a new list of geometries paired up with the value of the coverage at each intersection.

  This method should return Optional.empty if this operation is not supported.

• getCoordinateReferenceSystem

  org.geotools.api.referencing.crs.CoordinateReferenceSystem getCoordinateReferenceSystem()

  Returns:

  the CRS that the underlying data is represented in

• getEnvelope

  default Optional<org.geotools.geometry.jts.ReferencedEnvelope> getEnvelope()

  Returns:

  the geographic bounds of the underlying data, if available.

• getScalarDataType

  default Type getScalarDataType()

  Description copied from interface: SelfDescribingScalarData

  Returns the RiskScape type that describes this data when extracted from a project and added in to a pipeline as a scalar value.

  It is referred to as the scalar type to make it clear it's not the same as the Type of the data contained within it, e.g. the Struct type of the relation (non-scalar) vs RelationType that represents the relation itself (scalar).

  Specified by:

  getScalarDataType in interface SelfDescribingScalarData

• asRelation

  default Optional<Relation> asRelation()

  Returns a tabular view of this data, or empty if it isn't possible. This method is here to support efficient and streaming through raster data - at the moment there's no perceived need to implement this for non-grid/pixel formats, such as hdf5/netcdf, but who knows what the future holds or what use cases this might allow... <mysterious-science-noises>

  The relation's type is expected to at least contain the values that the coverage yields, plus the geometry at each location in the coverage.
