geometric accuracy,spatial detection error.Attribute accuracy is 
assessed in the form of confusion matrix,while geometric 
accuracy is estimated by the consistency of area and shape.We 
take advantage of three accuracy assessment methods in this 
researchioverall accuracy(the proportion of changed and 
unchanged area that are correctly classified by the 
method),omission error (the proportion of omitted changed 
area),and commission error(the proportion of falsely detected 
unchanged area).

Figure 2. Instruction of workflow 
5. RESULT AND DISCUSSION 
The whole technical workflow is finished under the 
environment of eCognition5.0 and CASMImageInfo3.0.The 
result of multiresolution segmentation is showed in Figure 
4.The parameters are 35 (scale parameter),0.3 (color 
weight).0.7 (shape weight),0.5 (compactness)and 0.5 
(smooth) respectively.
