How to do it...

1. Start ArcGIS Pro.
2. In the ArcGIS Pro start window, click Open another project.

1. Select Computer from the Open window and then click Browse in the area on the right:

1. Navigate to C:\Student\ArcGISProCookbook\Chapter2\RasterVector by clicking on C:\ in the area on the left of the Open Project window. Then double-click the Student, ArcGISProCookbook, Chapter2, and RasterVector folders.
2. Select the RasterVector.aprx project file and click OK.

The project will open with a single aerial photograph. An aerial photograph is one example of raster data and is one of the most common you will use.  

1. Select the Map tab in the ribbon and then click the small arrowhead located under Bookmarks.
2. Select the Raster 1 bookmark to zoom into to a specific location in the map.

Your map should now zoom in very closely to the aerial you were just viewing:

The aerial now looks like a series of individual squares. These are called cells, though many people mistakenly refer to them as pixels.

1. Activate the Explore tool on the Map tab in the Navigate group.
2. Click one of the cells in the Aerial Photo to see what information is linked to the cell you selected:

As you can see, the cells store information. In this case, it stores the values used to display the Red, Green, and Blue bands stored in the photo. When these three bands are overlapped, you are able to see the true color.

1. Close the information window by clicking the small X in the upper-right corner.
2. Right-click the Aerial Photo layer in the Contents pane and select Properties.
3. Click Source in the right-hand side of the Layer Properties window.
4. If needed, expand the Data Source option by clicking the small arrowhead.
5. Look at the Dataset cell in the presented table.

1. Click OK when done.

1. Right-click the Aerial Photo layer in the Contents pane and select Zoom to Layer.
2. In the Catalog pane located on the right side of the ArcGIS Pro interface, click the Portal tab located at the top of the pane next to Project.
3. Click the Living Atlas button, as shown here:

1. In the Search cell, type DEM.

1. Right-click Terrain: Hillshade and select Add to Current Map:

You have just added a raster layer that comes from a web service hosted in Esri's ArcGIS Online living atlas. Data in the Living Atlas is available to everyone for use in ArcGIS Pro and other GIS applications.

1. Click the Full Extent button located in the Map tab in the Navigate group. It looks like a small globe. This takes you to the full extent of the map. You will see more of the new Terrain layer you just added.
2. Now you will take a closer look. In the Map tab, click the arrowhead located under Bookmarks and select DEM Zoomed:

1. Look at the two raster layers now present in the map and compare the two.

1. Activate the Explore tool in the Map tab.
2. Click a cell in the Terrain: Hillshade layer to access the information linked to the cell.
3. Review the information presented. Compare it to the information you saw when you did the same thing for the Aerial Photo layer.

1. Close the information window when you are done.

As you can see, the Terrain layer you added was a good bit different than the Aerial Photo layer even though they are both rasters. The Aerial Photo layer has three bands, where the Terrain has a single band. The Terrain also has more information attached to each cell than the Aerial Photo. That is because the terrain was created to do more than just present a picture. It is designed so you can determine the elevation of an area and perform analysis based on the elevation. You will get a chance to do that later in this book.

Now, you will look more closely at vector data. The majority of the data you will work with will most likely be stored as a vector, meaning it will be either a point, line, or polygon.

1. Click the Full Extent button to see the entire map.
2. Turn off the Terrain: Hillshade layer by clicking the check box located next to the layer name.
3. In the Catalog pane, select the Project tab at the top of the pane.
4. Expand the Databases folder so you see the two geodatabases connected to the project.
5. Expand Trippville_GIS.gdb so you can see its contents.
6. Expand the Base Feature Dataset in the Trippville_GIS geodatabase.

1. Select the Parcels feature class and then drag and drop it into the map view.
2. Click the arrowhead under Bookmarks on the Map tab and select Parcels.
3. Activate the Explore tool on the Map tab and click one of the parcels displayed in the map.

1. Close the Information window.
2. Right-click the Parcels layer in the table of contents. Select Attribute Table from the menu that appears:

You should see Attribute Table open at the bottom. This is another way to view attributes associated with a vector layer.

You should see the same fields of information in both the Explore tool information window and the attribute table. However, how the information is presented is quite different. The attribute table presents data for all features in the layer in a tabular format. The information window only presents the information about one feature at a time.  

1. Activate the Select tool in the Map tab.
2. Double-click one of the Parcels in the map.
3. Look at the bottom of the Parcels attribute table you have opened. It should say 1 of 8,129 selected.

1. Click the Show selected records button located to the left:

Only a single record should be displayed now because you only have a single parcel selected.

1. Click the Select tool again.
2. Click the upper-left side of the map and draw a rectangle similar to the following image:

1. Look at the Parcels attribute table now. You should see an additional records appear in the table now that they are selected.

When working with vector data there is a one-to-one relationship between features in the map and records in the attribute table.

1. Click the Clear button located on the Map tab in the Selection group to deselect all selected features.
2. Close the attribute table by clicking the small X located next to the word Parcels in the small tab at the top of the table.  
3. Now click the Edit tab in the ribbon.

1. Activate the Select tool on the Edit tab.
2. Click one of the small parcels located along the road. The parcel should now be selected.
3. Click the Vertices button located in the Tools window on the Edit tab in the ribbon.

1. Notice the change in the display of the parcel. You should now see the vertices that form the parcel polygon.

Vector data is stored using the x, y coordinates of the vertices that form the feature. As you have seen, each of those features is then linked to additional attributes that are stored in the attribute table. So, all vector data includes two components, geometry, and attributes. A group of vector data that shares the same geometry (point, line, or polygon) and the same attribute table is called a feature class.

1. Zoom to the full extent and save your project.
2. If you are not continuing to the next recipe, close ArcGIS Pro.
