Method Detail

getGridAxisDescription

public GridAxisDescription getGridAxisDescription()

identifies each axis of the grid

getGridSpacing

public GridSpacing getGridSpacing()

GridSpacing is required for rectified grids, but undefined for other grids. It provides the ground resolution (pixel size or post spacing) along each dimension of the grid, expressed in the units of the (rectified) grid’s Coordinate Reference System

getGrid

public Grid getGrid()

Either Grid or RectifiedGrid is required. Both elements list the upper and lower bounds of the grid coordinates along each of the grid axes. (These are integer pixel or post coordinates, expressed in the grid’s internal coordinate reference system. The lower bounds are commonly defined as zero.)

getRectifiedGrid

public RectifiedGrid getRectifiedGrid()

Either Grid or RectifiedGrid is required. Both elements list the upper and lower bounds of the grid coordinates along each of the grid axes. (These are integer pixel or post coordinates, expressed in the grid’s internal coordinate reference system. The lower bounds are commonly defined as zero.)
