The importance of spatial data application has been fully displayed in Wenchuan earthquake relief activities. Spatial data has been the basic factor of various relief activities. Wenchuan earthquake relief process also uncovered many problems on the spatial data emergency application of our country. The exertion of spatial data has been greatly controlled by the coordination capability of each department during data collecting and sharing processes.
