You can create a new polygon in ArcMap using the Polygon tool. This tool allows you to draw polygons by clicking points on the map.
Here's how to create a new polygon in ArcMap:
- Open ArcMap and load the desired map.
- Click the "Editor" toolbar to activate editing mode.
- Click the "Polygon" tool on the toolbar.
- Click points on the map to define the vertices of the polygon.
- Double-click the last point to close the polygon.
You can also use the "Sketch" tool to draw a freehand polygon. To use the Sketch tool:
- Click the "Sketch" tool on the toolbar.
- Draw the polygon by dragging the mouse.
- Double-click to close the polygon.
Once you have created a polygon, you can edit its attributes by selecting the polygon and opening the Attribute Table. You can also change the polygon's symbology by right-clicking on the polygon and selecting Properties.
Remember that the "Edit" menu provides additional options for creating and editing polygons, including:
- "Construct Polygon": This tool allows you to create a polygon by specifying its sides and angles.
- "Finish Sketch": This tool allows you to finish a polygon that is not yet closed.
- "Delete": This tool allows you to delete a polygon.
- "Cut": This tool allows you to cut a polygon and paste it elsewhere.
- "Copy": This tool allows you to copy a polygon and paste it elsewhere.
By following these steps, you can create and edit polygons in ArcMap.
