H. The common delineated files are read A. Data files for pre defined study area created during 
back by ArcView or Arc/Info. Spatial-EPIC data extraction process 
G. It creates ArcView, Arc/Info readable B. Batch files are created which invokes Spatial-EPIC 
fileformat. to use different management files during simulation. 
F. These files are fed to in house developed C. Common data file created for required parameters used 
program to convert into ArcView readable format. under the model from gathered data of study area. 
E. Spatail-EPIC generates user selected output D. User created spatial dataset as input data in the text array
