Given a multi-resolution level, generate center points of each grid box by G"{o}ttlemann's method, modified G"{o}ttlemann's method or standard method.

Usage

modregcenter(l) # for modified G\"{o}ttlemann's regular grid
modredcenter(l) # for modified G\"{o}ttlemann's reduced grid
gotregcenter(l) # for G\"{o}ttlemann's regular grid
gotredcenter(l) # for G\"{o}ttlemann's reduced grid
regcenter(l)    # for standard regular grid
redcenter(l)    # for standard reduced grid

Arguments

l an integer which denotes the index of multi-resolution level

Details

It is for obtaining the center points of each grid box from the grid according to multi-resolution level. The values will be used for network design.

Value

center center points from grid
