Introduction to ArcGIS Pro (Part 5): Editing and Deleting Features
Welcome back! I promise you we are soon done with digitizing. Before moving on to our analyses, I want to show you how to edit and delete features. This should feel very familiar if you worked along with the previous part.
Let’s get moving. In this part we are going to look at editing features. Since this part uses many of the same workflows as the previous part, I will spend less time explaining certain processes. If you are in a doubt anyway, look back at the previous part or send me a comment.
We will start editing one tram station, followed by editing a park. Finally, we will quickly look at how to delete features.
Moving a tram station
- Open the Locate tool on the Map tab to show the Locate pane.
- Insert the following coordinates: 4.9333501°E 52.3607334°N. This will zoom you into an area with a tram station and line. Make sure your screen covers the following area:
- I don’t like how the station is not touching the tram line, and I would also like to remove the tram line loop. Let’s start by modifying the station first. Start by pressing the Modify button on the Edit tab.
- Now press Move on the modify features tab, followed by clicking the tram station (the red circle).
- Hover over the tram feature until you see a move symbol, and click and drag it over to the line above. The exact location is not that important, this is just for practice. Finish by pressing F2 or by clicking the finish button on the lower end of your map view. The new location should look something like this:
Deleting a tram line
Now let’s get rid of that looped tram line. Note: This is by any means not a mistake in the dataset. The tram line is probably used to turn around tram cars, but for the sake of this exercise, this makes for good practice.
- This is actually very easy. Click the looped tram line.
- You can see that tram line is selected by its blue color. You will also note the green vertices, which you could move if you wanted to make smaller adjustments.
All we are interested in however is deleting it. This is done by simply either pressing the Del button on your keyboard, or by clicking the Delete button on the edit tab (in the Features group).
Editing a park
Let’s finish up by looking at how to edit a feature. When editing stations (points), we could basically only move or delete the specific point. Since parks are polygons, however, we can many more options.
- Use the Locate pane (On the Map tab, press the locate button) enter the following coordinates: 4.9517579°E 52.3617682°N.
- Make sure to zoom in or out so you can see the whole park polygon. Your scale should be around 1:6000.
- On the edit tab, press Modify, followed by pressing Vertices on the Modify Features pane.
- Select the park polygon. Your map view should look similar to this:
- Now, we want to move vertices (or delete them) so that the 2 gaps are removed from the polygon. We basically want to make sure the polygon fills the whole park area. Start in the bottom left zone. Click the Delete vertex button on the bottom of your map view.
- Click every vertex on the bottom left that does not lie on the outer border. Every time you left click a vertex the polygon will grow in size. When you are done the whole gap should be filled. Finally, press the Finish button found close to the Delete button from before.
- Do the same for the gap on the top. Just remove all vertexes around the gap, and the gap should be filled.
- Finally, let’s move our attention to the top right area.
- If needed, press Modify on the ribbon, followed by pressing Vertices on the Modify Features pane. Select the polygon again.
- Make sure the Normal button is selected on the bottom panel (instead of the Delete button). It should be the most left button.
- Click, hold, and drag existing vertexes. You can, for example, start by dragging the top right vertex further right, on the border with the water.
- Move more vertexes so that their location makes sense. You can also use the Add tool to add more vertexes. Go ahead and experiment! When you are all done, click Finish, followed by Save on the edit tab. The end result could look like this:
Great job! We are done with our little digitizing adventure. I hope you have a better idea of how to edit features. Now it’s time for the cool part. We will run our analyses in part 6!
