Figure 1. Brief schematic Presentation of modeling
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
file per day/month/yearly basis. format for model calculation.

yearly For example, crop, tillage, fertilizer, pesticide and so on..
3. The Spatial-EPIC output files are read by the in house developed program which
—— Data Flow generates ASCIIGRID text file format.
