+In order to preserve spatial detail, it is recommended to densify linear 
+features with <em><a href="v.split.html">v.split</a></em> before 
+reprojecting. Depending on the source and target CRS 
+(Coordinate Reference System), geometries can be substantially 
+deformed (straight lines become curves, squares become trapezoids, etc). 
+In these cases densification of linear features can help to avoid 
+topological errors.
