ARCTUTOR 10 PDF

You will use the editing environment in ArcMap to create and modify spatial features to represent various natural and human-made phenomena in the park. After completing these exercises, you are able to create different types of new features, including points, lines, polygons, and text; assign attribute values; edit shapes; and build and use feature templates. You will also become familiar with many of the tools and parts of the user interface available to you when editing. The remaining exercises Exercises 4—5 show you how to edit data.

You will use the editing environment in ArcMap to create and modify spatial features to represent various natural and human-made phenomena in the park. After completing these exercises, you are able to create different types of new features, including points, lines, polygons, and text; assign attribute values; edit shapes; and build and use feature templates.

You will also become familiar with many of the tools and parts of the user interface available to you when editing. The remaining exercises Exercises 4—5 show you how to edit data. You will learn how to maintain spatial integrity through topology and how to integrate new data with existing datasets using spatial adjustment. You should complete the tutorial in sequence, since the software methods build on those introduced in earlier exercises and assume you understand those concepts.

For exercises 1—3, you should complete the all subparts such as a, b, c, and d at the same time, then only stop after completing a whole exercise. For exercises 4—5, you can restart the tutorial again on either the next exercise or subpart without any difficulty since the maps and data are independent in these exercises.

Overview of the tutorial exercises The tutorial is divided into a series of exercises and subparts: Exercise 1 introduces the editing environment, including the terminology and ArcMap user interface. You learn how to create new points, digitize lines and polygons on the map, change editing tools, utilize snapping while creating features, and use feature templates. Exercise 2 builds on these skills. You learn how to create features from existing features and how to edit existing features.

Exercise 3 is all about text on your map. You convert labels to geodatabase annotation, place the text on the map, and create new annotation features using the editing tools. Exercise 4 shows you how to edit features to maintain spatial integrity.

You use map topology to edit shared features and geodatabase topology to ensure that your line features connect properly. Exercise 5 uses spatial adjustment to transform and align your spatial data and transfer attributes among features. Note: The tutorial assumes that you are using the default settings for the editing environment. If you have customized your options, you may need to reset them to match the steps in the tutorial.

For example, by default, angular measurements are entered in degrees using the polar system, which is the format of the values provided in the tutorial. You can change the settings for the editing environment on the Editing Options dialog box, which is opened by clicking the Editor menu on the Editor toolbar and clicking Options. Map topology datasets are courtesy of the United States Geological Survey.

The world imagery is a web-based layer being served from ArcGIS.

Exercise 1a: Creating new points

Once the feature is created, you will then add attribute values to the point. You are introduced to the Editor toolbar, the Create Features window, and the Attributes window, which are the main elements of the ArcMap user interface when editing. To start this exercise, you first need to zoom the map to your area of interest. A spatial bookmark, which is similar to a bookmark in a Web browser, is a way to save frequently used locations on your map so you can easily access them. A bookmark has been created for you containing the map extent in which you will be working.
