# EW volume comparison between MiTS 1 and MiTS 2

**Objective**: Comparison of Earthwork volume between MiTS 1 and MiTS 2

There are few parameters that we will keep constant to reduce the discrepancy between each project file. The parameters are listed as follow:

1. Using TIN as meshing method
2. Grid size
   - Angle: 0
   - Interval: 5m
   - Left offset: 2.5m
   - Right offset: 2.5m
3. End-Area
   - Interval: 5m

## With slope

Swell/Shrink Factor: 1.00

## Conclusion

In conclusion, for DEM and End-Area Method, the results obtained from MiTS 1 and MiTS 2 typically show a little discrepancy of less than 1%, which can be attributed to algorithmic improvements made in MiTS 2. Whereas for Grid Method, there are significant differences between the results obtained in MiTS 1 and MiTS 2. This happens because one limitation of the Grid Method used in MiTS 1 is that it does not account for the effects of slope, resulting in identical EW volumes regardless of slope information. However, this limitation has been fixed and improved in MiTS 2.
