This step involves using the native data structure for ArcGIS called a geodatabase. A geodatabase is like a container that can hold many types of geospatial datasets. It is a way to organize and manage related datasets. There are several different types of geodatabases. The one covered here is called a file geodatabase, which can store individual datasets up to one terabyte (TB) in size.
In ArcMap, right-click on the working folder in the Catalog Window. Select New, then File Geodatabase (Figure 2.09).
The geodatabase should appear in your working folder with the default name, New File Geodatabase (Figure 2.10).
Change the name to something more meaningful, such as your initials, followed by World Data (Figure 2.11). Spaces are OK to use when naming geodatabases.
When saving files, ArcMap uses a default geodatabase as an output location. As a result, many readers encounter a situation where they forget to specify the output location, and data gets saved to the default geodatabase. This mistake may lead to lost data or other unforeseen problems. In this step, you set the default output location to the geodatabase you created.
From the File menu, open the Map Document Properties window. Next to Default Geodatabase click the yellow file folder icon to browse to your working folder (Figure 2.12).
If you do not see your workspace folder in the Default Geodatabase window, use the drop-down menu to locate it (Figure 2.13).
Navigate to your working folder and select your World Data geodatabase. When ready, click ADD (Figure 2.14).
When you return to the Map Document Properties window, be sure to check the box next to Store relative pathnames to data sources (Figure 2.15). When ready, click OK.
