Steps to reproduce

Invoke an app with GIS functionalities (the contributor use QGIS) to incorporate the datasets. Set the coordinate systems to EPSG-4301. 1. Contours: named eXX-contour.shp If 'area' >0, then that means hill, if 'area' < 0, then means depression. 2. Streamlines: named eXX-stream.shp If 'direction' = 1, then that means upward streamline, if 'direction' = 2, then means downward streamline. 3. Slope analysis: named e0.1-slope.shp
