Importing and Exporting Data in the Project Geodatabase

For this tutorial, we are working with vector data which is a spatial data format that uses points, lines, and polygons to represent real features on the earthEarth's surface. Vector data is ideal for discrete themes with definite boundaries. A Feature Class is a vector storage data format that represents a homogeneous collection of common features. There are two types of Feature Classes: a Shapefile feature class and a Geodatabase feature class. A Shapefile feature class is an open source format. Its file extension is .shp and its icon is green. A Geodatabase feature class is an Esri proprietary format. A Geodatabase feature class must be stored inside a Geodatabase (.gdb) and its icon is white. To better organize our project, we will import the data we downloaded and the NHGIS sample data into our Project Geodatabase.

1. In the Catalog pane, click the US_tract_1980_Harris_County geodatabase feature class located in the NHGIS folder and drag-and-drop it up into the Intro_Part2.gdb. A progress bar will appear that reads 'Copying...' Once it is complete, you will see a copy of US_tract_1980_Harris_County inside the Intro_Part2.gdb as shown below.
   
   
   
   
2. Repeat the above step to drag-and-drop Major_Rivers from the Major_Rivers.gdb into the Intro_Part2.gdb. 
3. COH_HISTORIC_SITESLANDMARKS is a Shapefile feature class, so it requires a different method to be imported into the Project Geodatabase. In the Catalog pane, right-click on COH_HISTORIC_SITESLANDMARKS.shp and select Export > Feature class(es) to geodatabase.
