Urban Open Space Study Based on Remote Sensing and Geographic Information Systems（GIS）

Open space is treated in many cultures as the common area where people conduct functional and ritual activities that bind a community in the normal routines of daily life or in penodic festivities.From the historical perspective,open space should be supportive,democratic,and meaningful.On the one hand,human culture shapes and reshapes its open spaces,whereas,on the other,open spaces can help to create a more humane culture.This duality suggests that the relationship of open space to public life is dynamic and reciprocal.New forms of public life require new spaces,and vice versa.
