Constructor Detail

RegularGridImpl

public RegularGridImpl(RegularAxis xAxis,
                       RegularAxis yAxis,
                       org.opengis.referencing.crs.CoordinateReferenceSystem crs)

RegularGridImpl

public RegularGridImpl(BoundingBox bbox,
                       int width,
                       int height)

Constructs a RegularGrid from the given bounding box, with the given width and height. Note that the bounding box represents the edges of the grid, whereas grid coordinates represent the centre of the grid points.

The coordinate reference system of the returned grid will be taken from the CRS of the bounding box. If this is null, the names of the axes will be set to "Unknown X axis" and "Unknown Y axis".

Parameters:

bbox - The bounding box of the grid

width - the number of grid points in the x direction

height - the number of grid points in the y direction

RegularGridImpl

public RegularGridImpl(double[] bbox,
                       org.opengis.referencing.crs.CoordinateReferenceSystem crs,
                       int width,
                       int height)

Constructs a RegularGrid from the given bounding box, with the given width and height. Note that the bounding box represents the edges of the grid, whereas grid coordinates represent the centre of the grid points.

Parameters:

bbox - the bounding box, in the form: [minx, miny, maxx, maxy]

crs - the CoordinateReferenceSystem of the bounding box

width - the number of grid points in the x direction

height - the number of grid points in the y direction

RegularGridImpl

public RegularGridImpl(double minx,
                       double miny,
                       double maxx,
                       double maxy,
                       org.opengis.referencing.crs.CoordinateReferenceSystem crs,
                       int width,
                       int height)

Constructs a RegularGrid from the given bounding box, with the given width and height. Note that the bounding box represents the edges of the grid, whereas grid coordinates represent the centre of the grid points.

Parameters:

minx - the minimum x value of the bounding box

miny - the minimum y value of the bounding box

maxx - the maximum x value of the bounding box

maxy - the maximum y value of the bounding box

crs - the CoordinateReferenceSystem

width - the number of grid points in the x-direction

height - the number of grid points in the y-direction
