Module 4 - Process Manning’s Roughness Data
===============================================

This module describes the workflow for converting land cover datasets into Manning’s n roughness surfaces using QGIS and online data services.

Work through **ONE** of the Land Cover methods.  The process is the same but the data is different.

The street data processing method is optional, but it provides valuable practice working with polyline data and buffer operations in QGIS.
