Method Detail

convertPixelDensityToScaleDenominator

public static int convertPixelDensityToScaleDenominator(double aPixelDensity,
                                                        ILcdGeoReference aGeoReference)

Deprecated.

Calculates the scale denominator that corresponds to the pixel density, assuming a pixel size of 0.28 mm.

Parameters:

aPixelDensity - the pixel density in pixels per square model unit

aGeoReference - the geographic reference

Returns:

the scale denominator, as scale = (1 / scale denominator)

getMaxLevel

public static int getMaxLevel(ILcdBounds aBounds,
                              ILcdGeoReference aGeoReference,
                              long aLevel0Rows,
                              long aLevel0Columns,
                              List<TLfnVectorAssetMetadata> aAllAssetMetadata)

Deprecated.

Computes the most detailed level that is needed for the assets in a coverage. The level is chosen such that its scale is greater than or equal to the largest asset scale.

Parameters:

aBounds - the coverage bounds

aGeoReference - the coverage geographic reference

aLevel0Rows - the number of rows at level 0 in the coverage

aLevel0Columns - the number of columns at level 0 in the coverage

aAllAssetMetadata - the assets

Returns:

the most detailed level, as number of levels = (max. level + 1)

getOptimalScaleDenominator

public static int getOptimalScaleDenominator(ILcdBounds aBounds,
                                             ILcdGeoReference aGeoReference,
                                             long aLevel0Rows,
                                             long aLevel0Columns,
                                             int aLevel)

Deprecated.

Compute the optimal scale of a coverage at the specified level. The scale is such that a tile will be mapped to 256x256 pixels.

Parameters:

aBounds - the coverage bounds

aGeoReference - the coverage geographic reference

aLevel0Rows - the number of rows at level 0

aLevel0Columns - the number of columns at level 0

aLevel - the level

Returns:

the scale denominator, as scale = (1 / scale denominator)

computeScaleDenominator

public static int computeScaleDenominator(ILcdModel aModel,
                                          ILcdStatusListener aStatusListener)

Deprecated.

Compute the scale of a model.

The status listener can be used to monitor the progress of the computation.

Parameters:

aModel - the model

aStatusListener - the status listener or null

Returns:

the scale denominator, as scale = (1 / scale denominator)
