Implementation of Meta Fractal Dimension Model on Local Fractal Description of Map Objects

As a main factor of fractal geometry,fractal dimension is used to quantificationally analyze the spatial complexity of map objects.But it is proved in practice that a map object(usually) shows nonuniformity of local fractal character.A meta fractal dimension model is put forward based on fractal theory that can be applied to describe the change of local shape of objects,and a new method for their further applications and analyses is offered.
