This sequence appears to outline a structured curriculum for learning GIS concepts and applications using QGIS, with a focus on hydrological and watershed analysis. Here’s a breakdown of the recommended approach to each week:
### **WK01: Recommended Folder Structure & QGIS Setup/Settings**
- **Folder Structure:**
- `Raw_Data`: Unprocessed datasets
- `Processed_Data`: Cleaned or clipped datasets
- `Outputs`: Final maps, reports, or figures
- `Scripts`: Python, R, or model scripts
- `Documentation`: Notes, metadata, or guidance documents
- **QGIS Setup/Settings:**
- Set project CRS (coordinate reference system) and on-the-fly projection
- Install essential plugins (e.g., QuickMapServices, Processing Toolbox, etc.)
- Configure snapping settings for precise editing
---
### **WK02: Using QGIS**
- **Key Tools & Features:**
- Enable and organize toolbars for navigation, measuring, and editing
- Explore and install useful plugins such as **GRASS**, **SAGA**, or **OpenLayers**
- Set up projections: Understand how to reproject layers
- Access REST services for live GIS data (e.g., WMS/WFS services)
- Learn filtering methods to display only relevant data in layers
---
### **WK03: USGS TNM Download and StreamStats**
- Access **USGS TNM** for 30m DEM and StreamStats for hydrology data
- Download Kanawha Basin data (e.g., WV Hydro, NSS Basin)
- **Merge and clip rasters:** Combine multiple rasters and trim to area of interest
- Apply symbology and color ramps for visual clarity
---
### **WK04: Filtering & Saving Flowline Layers**
- Filter flowline layers to isolate relevant streams or features
- Use **selection tools** for visual basin delineation
- Apply the **Dissolve** tool to combine basins or administrative units
---
### **WK05: Map Symbology & Transportation Data**
- Enhance maps with meaningful symbology (colors, classifications)
- Review attributes with the **Measure Tool** or **Attributes Toolbar**
- Use **Field Calculator** to add geometry attributes (e.g., area, perimeter)
- Download transportation data, merge datasets, and dissolve redundant geometries
- Assign unique IDs and delete unnecessary fields for cleaner data
---
### **WK06: Seed File & River Analysis**
- Create a new seed file containing all key reference layers
- Identify and count river crossings by basin
- Measure river miles and calculate sums by basin
- Use tools like **Refactor Fields** and **Aggregate** to streamline data
---
### **WK07: Table Joins & Micro Basins**
- Perform multiple table joins to enrich watershed data
- Finalize the Kanawha Basin analysis
- Transition focus to micro-basins for localized studies
---
### **WK08: Micro Basin Analysis (Galax, VA)**
- Use StreamStats to delineate micro-basin for Galax, VA
- Download and process a DEM for sub-basin creation
- Prepare for advanced watershed modeling
---
### **WK09: Raster Analysis with r.watershed**
- Use GRASS GIS tools like **r.watershed** to analyze flow accumulation
- Explore raster math concepts for hydrological accumulation
---
### **WK10: Toolbox Models**
- Introduction to the **Processing Toolbox**
- Use pre-built H&H Toolbox models for micro-watershed analysis
---
### **WK11: Landcover, Slope & Geomorphons**
- Analyze landcover using raster data
- Compute slope and geomorphons (landform classification) using terrain tools
---
### **WK12: Precipitation Map**
- Select small watersheds for focused studies
- Overlay precipitation data to visualize spatial distribution
---
### **WK13: Final Project Map**
- Create maps for the final project, focusing on visual and analytical clarity
- Incorporate key findings and annotations
---
### **WK14: Distance Map Project**
- Develop a distance-based map as a practical example for the final project
- Demonstrate tools like cost-distance analysis or proximity calculations
---
### **Tips for Success:**
2. **Backup:** Frequently save and backup your work.
3. **Ask Questions:** Use forums or communities like GIS Stack Exchange if you face challenges.
