How do I trace a shapefile in QGIS?
Quote from video: Area first thing we're going to add the digitizing toolbar. So that'll that'll bring us up some tools to let us do the editing. And then we're also going to right click and add the snapping toolbar.
How do I put GPS coordinates into a shapefile?
To add GPS points as a graphic in your map document, use the Go to XY tool on the Tools menu. Select the coordinate system units and enter the XY coordinates. To insert the XY coordinate as a graphic to your ArcMap document, select Add Point.
How do I enable georeferencing toolbar in QGIS?
If you can’t find Georeferencer, you may need to manually add the Georeferencer plugin under the Plugins->Manage and Install Plugins menu. Search for the “Georeferencer” plugin and check the box next to it. If the box is checked, Georeferencer should now be accessible in QGIS.

How do you extract a polygon?
To extract based on a polygon in a feature class instead of providing a series of x,y pairs, you can use the Extract By Mask tool. The polygon object may consist of just one part, or many parts as a polygon class. In the later case, all polygon parts must be contiguous, such that they could be outlined by one polygon.
How do you identify a polygon?
A polygon is a two-dimensional closed figure that has three or more straight sides. Any figure with straight edges, such as a triangle or rectangle, is a polygon. Figures that have any curved sides or open sides are not classed as polygons.
