B.2.2.1 Gridline registration

In this registration, the nodes are centered on the grid line intersections and the data points represent the average value in a cell of dimensions ( ) centered on the nodes (Figure B.1). In the case of grid line registration the number of nodes are related to region and grid spacing by

which for the example in Figure B.1 yields .
