All Implemented Interfaces:

public class TLcdE57ModelDescriptor
extends ALcdLIDARModelDescriptor
implements ILcdDataSourceModelDescriptor<ILcdDataSource>, com.luciad.internal.format.las.ILinPointCloudModelDescriptor

Model descriptor for data decoded from an E57 (.e57) file.

• It contains various fields available in the .e57 header.
• It implements ILcdDataModelDescriptor and getPropertyRange to see what properties are available in this model.

Data model

Although the elements in the model are not data objects themselves, you can still use the data model to access properties of individual points when you use it to build expressions for use in styling.

The data model has a single type that consists of the properties available in the source file. Only the properties available in the source file are available in the data type, for example if a file does contain color information, but does not contain timestamp information, the data type will have a ALcdLIDARModelDescriptor.COLOR property, but not an TIME_STAMP property.

You can find the names of all the possible properties as constant fields in TLcdE57ModelDescriptor: ALcdLIDARModelDescriptor.COLOR, ALcdLIDARModelDescriptor.INTENSITY, ROW_INDEX, COLUMN_INDEX, and so on.

You can use getPropertyRange(com.luciad.datamodel.TLcdDataProperty) to get the extent (minimum and maximum value) of a specific property in this specific model.

Method Detail

getDataSource

public ILcdDataSource getDataSource()

Description copied from interface: ILcdDataSourceModelDescriptor

Returns the object that was used to decode the corresponding model.

Specified by:

getDataSource in interface ILcdDataSourceModelDescriptor<ILcdDataSource>

Returns:

an object describing the data source(s) of the corresponding model. This can be null, e.g. when the model was not decoded by using an ILcdDataSource.

See Also:

ILcdModelDecoder

getModelTypes

public Set<TLcdDataType> getModelTypes()

Returns a single data type that describes the individual points in the elements of this model.

See class javadoc for more details on the data model.

Specified by:

getModelTypes in interface ILcdDataModelDescriptor

Returns:

The single data type that describes the individual points in the elements of this model.

getPropertyRange

public ILcdInterval getPropertyRange(TLcdDataProperty aProperty)

Description copied from class: ALcdLIDARModelDescriptor

Returns the range of values for the given property for this model.

Only returns an interval for properties with numeric values, otherwise returns null.

Also returns null if the property is not available in the data type of this model.

Specified by:

getPropertyRange in class ALcdLIDARModelDescriptor

Parameters:

aProperty - the property to get the range for.

Returns:

The range, or null if the property is not available in the file, or if the property does not have a range.

getDataType

public TLcdDataType getDataType()

Returns the single data type that describes the individual points in the elements of this model.

This is the same data type as in getModelTypes().

See class javadoc for more details on the data model.

Returns:

The single data type that describes the individual points in the elements of this model.

getGUID

public String getGUID()

Gets the globally unique identifier of this dataset, if available

Returns:

the globally unique identifier of this dataset

getNumberOfPoints

public long getNumberOfPoints()

Returns the Number Of Point Records as specified in the .e57 header.

Note: the actual amount of points in the model may be different, for example because of filtering or setting a maximum.

getNumberOfPoints in interface com.luciad.internal.format.las.ILinPointCloudModelDescriptor

Returns:

The number of points in the file.

getCreationTime

public Instant getCreationTime()

Gets the time instant when the E57 file was created, if available
