Field Detail

crsStr

protected java.lang.String crsStr

The string of the detected CRS

crs

protected org.opengis.referencing.crs.CoordinateReferenceSystem crs

The detected CRS or null if either there was no CRS in the chunk or if it was invalid

flippedCRS

protected boolean flippedCRS

True if x and y are flipped in crs

transform

protected org.opengis.referencing.operation.MathTransform transform

A transformation from crs to WGS84. null if crs is also null.

srsDimension
