The transform of the national geographic grids for China based on the axial minimum enclosing rectangle

Abstract

Put forward a method of the transform between the different style of geographic grids, define the axial minimum enclosing rectangle, give the model for the code transform between the theodolite coordinate grid and the gauss coordinate grid, realize the transform of the national geographic grids based on the axial minimum enclosing rectangle, and then put forward the method of the grid transform for irregular region. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
