ILcdBounded

public class TLfnRasterAssetMetadata
extends ALfnAssetMetadata

A representation of a raster asset. It has TLfnRasterAssetMetadata.RasterAssetParts as its asset parts. Instances of this class are immutable, thus thread-safe.

Simple raster data

Simple source data is data that can be modeled as a model with a single ALcdImage or ILcdRaster element. This covers the most common formats such as GeoTIFF, DTED, ECW ...

• Initially, each image corresponds to a single asset with a single raster asset part.
• You can manually group raster asset parts in a single asset, as long as they have a common geographic reference, clipping shape, type and supported coverage types.
• An asset part can have a tile set structure, which means that its model element is an ILcdEarthTileSet. In that case, the fusion engine can fuse it more optimally in common circumstances.

Example: ECDIS data

• Each ECDIS cell is modeled as a separate raster asset part, with its own bounds and pixel density.
• The pixel density is derived from the navigational purpose scales of the source data.
• Even though the class is TLfnRasterAssetMetadata, the type is ELfnDataType.VECTOR.

Example: NetCDF data

• Each NetCDF variable is modeled as a separate asset part with a parameter corresponding to the variable.
• There are some special cases such as U and V components of wind, which are modeled as an asset part with two parameters, one for each component.
• Each raster asset part can define multiple dimensions, such as time of day and level in the atmosphere. The dimensions define all the possible values available in the source data.
• The set of possible values is modeled by ILcdDimension.getValues(), but is assumed to be finite, which is virtually always the case. Infinite possible values are not supported.

Method Detail

getAssetParts

public List<TLfnRasterAssetMetadata.RasterAssetPart> getAssetParts()

Description copied from class: ALfnAssetMetadata

Gets the parts of this asset as a Collection.

OGC filter property XPath: lts:AssetPart

Overrides:

getAssetParts in class ALfnAssetMetadata

Returns:

the Collection of the parts of this asset, never null or empty

getPixelDensity

public double getPixelDensity()

Deprecated. use TLfnRasterAssetMetadata.RasterAssetPart.getResolutions() instead

Gets the pixel density of this raster asset.

The pixel density is the maximum pixel density of all the parts of this asset.

Returns:

the pixel density, a decimal number in the range [0, +Infinity]

See Also:

TLfnRasterAssetMetadata.RasterAssetPart.getPixelDensity()

getParameters

public List<TLcdEarthMultivaluedDataParameter> getParameters()

Gets the parameters of this raster asset.

The parameters of the asset is the union of the asset part parameters.

Returns:

the parameters of this raster asset, possibly empty but never null

See Also:

TLfnRasterAssetMetadata.RasterAssetPart.getParameters()

accept

public void accept(ALfnResourceMetadataVisitor aVisitor)

Description copied from class: ALfnResourceMetadata

Accepts the visitor for visiting this resource. This provides a double-dispatch.

Specified by:

accept in class ALfnResourceMetadata

Parameters:

aVisitor - the visitor

ALfnResourceMetadataVisitor

asBuilder

public TLfnRasterAssetMetadata.Builder asBuilder()

Description copied from class: ALfnResourceMetadata

Creates a new builder from this resource metadata. The builder's fields are initialized to the values of this resource metadata. The builder will build a resource metadata of the same type as this instance.

Specified by:

asBuilder in class ALfnAssetMetadata

Returns:

a new builder

newBuilder

public static TLfnRasterAssetMetadata.Builder newBuilder()

Creates a new builder. The builder's fields are initialized to the default values.

Returns:

a new builder

newBuilder

public static TLfnRasterAssetMetadata.Builder newBuilder(TLfnRasterAssetMetadata aTemplate)

Creates a new builder from a given template. The builder's fields are initialized to the template's values.

Parameters:

aTemplate - the template to create a builder from

Returns:

a new builder
