🟫✅ How to Create a Polygon Layer and Add Polygons in QGIS

🟡 Step 1: Open QGIS and Create a New Polygon Layer

1. In QGIS, go to:

   Layer → Create Layer → New Shapefile Layer…

2. In the New Shapefile Layer dialog:

   • Geometry Type: Select Polygon

   • Coordinate Reference System (CRS): Choose one (e.g., EPSG:4326 – WGS 84)

   • Add Attribute Fields (optional but useful):

     • Name → Text (String)

     • ID → Whole Number (Integer)

   • Click OK

3. Save your new file as (e.g., My_Polygons.shp)

🟡 Step 2: Add the Polygon Layer to Map

• It will appear automatically in the Layers Panel.

• You’ll see the layer name like My_Polygons.

🟡 Step 3: Enable Editing Mode

1. Right-click your polygon layer → Toggle Editing
   or click the ✏️ Pencil icon on the top toolbar.

🟡 Step 4: Add Polygon Features

1. Select the Add Polygon Feature tool (🟦 icon with a + symbol).

2. Click on the map to draw the shape:

   • Each click creates a vertex (corner)

   • Right-click to close the shape and finish drawing

3. A form will appear to enter attribute data (e.g., Name, ID)

4. Click OK

5. Repeat to add more polygons.

🟡 Step 5: Save and Stop Editing

• Click 💾 Save Layer Edits

• Then click ✏️ Toggle Editing again to finish.

🟢 Done!

You’ve successfully created a polygon layer and added polygon features.

🔧 Bonus: Editing Polygon Shape

• Use the Vertex Tool to move, add, or delete corners.

• Use Cut or Split Tools for advanced editing.
