Obtaining the Tutorial Data

There are two ways of obtaining the tutorial data. Option 1 is best if you are completing this tutorial in one of our short courses or from Fondren Library and Option 2 is best if you are completing the tutorial from your own computer.

...

If you are completing this tutorial from a public computer in Fondren Library and are logged on using the gistrain profile, follow the instructions below:

1. On the Desktop, click the File Explorer icon Image Added located on the Windows Taskbar at the bottom left corner of the screen.
2. In the 'File Explorer' window, click This PC on left side panel and then navigate to  double-click the Computer icon > gisdata (\\file-rnas.rice.edu) (R:) > Short_Courses > HIST207 > HIST207_GDC1  
3. To create a personal copy of the tutorial data, drag the Intro_Part1 folder onto the Desktop. 
4. Close all windows.

3. Maximize the ArcGIS Pro application window.

Creating a New Map

A map is a project item used to display and work with geographic data in two dimensions. The first step to visualizing any data is creating a new map. 

The ribbon runs horizontally across the top of the ArcGIS Pro interface. Tools (buttons) are organized into tabs along the ribbon.

1. On the ribbon, click the Insert tab.
2. In the Project group, click the New Map button.
   
   

You will notice that a new map Map view opens in the main section of ArcGIS Pro.

The panel on the left side of ArcGIS Pro is called the Contents pane. After creating a new map, the Contents pane now displays the default Map Map title and automatically adds the Topographic basemap layer to the map.

...

1. Right-click the COH_HISTORIC_DISTRICTS feature class and select Add To Current Map.
2. An alternative method of adding data to a map is to click and hold the Major_Rivers feature class and drag and drop it into the Houston History map view Map view.
3. Repeat either of the above two options methods to add COH_HISTORIC_SITESLANDMARKS to the Houston History map Map view.
4. Above the ribbon, on the Quick Access toolbar, click the Save button.

...

It is early in the project to be deciding upon symbology, however, when layers are added to a map, ArcGIS Pro assigns then layers a random color symbol. Sometimes the colors are very faint and difficult to see on top of the basemap or the colors of multiple layers are very similar to each other and difficult to distinguish. To ensure that everyone can easily see the layers we are working with, we will adjust the basic symbology.

1.  In the Contents pane, right-click the Major_Rivers layer name and select Symbology to open the Symbology pane on the right.

Notice that the 'Primary symbology' defaults to Single Symbol. With this type of symbology, all features in that particular layer will be assigned the same symbol.

1. For 'Symbol', click the colored line symbol to switch to Format Line Symbol mode.
   
   
   
   
   
2. Within Format Line Symbol mode, click the Properties tab.
   
   
   
   
3. For 'Color', use the drop-down menu to select Cretan Blue. The rivers on the map should now all be blue and easily visible.
4. At the bottom of the At the bottom of the Symbology pane, click Apply.

The rivers on the map should now all be blue and easily visible. The 'Format Symbol' mode of the Symbology tab can also be accessed directly via the small layer symbol (instead of beneath the layer name ) in the Contents pane.

1. In the Contents pane on the left, click the colored rectangle symbol beneath the COH_HISTORIC_DISTRICTS layer name.

2. For 'Color', use the drop-down menu to select Mango.
   
   
   
   
3. For 'Outline color', use the drop-down menu to select Gray 50%.
4. At the bottom of the Symbology pane, click Apply.

...

1. Repeat either of the above two methods to change the symbology of COH_HISTORIC_SITESLANDMARKS to: 'Color' = Burnt Umber and 'Size' = 5 pt.
2. Your three layers should now look like the below image.

Navigating the Project

Navigating the Contents Pane

At the top of the Contents pane, there is a series of seven buttons. By default, the leftmost button is selected: 'List by Drawing Order'.

When this button is selected, the order in which the layers are listed corresponds to the order in which the layers are visually stacked in the Map view. To test how the drawing order works, you will reorder the layers.

...

1. Uncheck the Major_Rivers layer to turn off its visibility in the map Map view.
2. Check the Major_Rivers layer to turn its visibility back on in the map Map view.

Navigating the Map

You will now learn how to navigate the Map view by panning, zooming, and using spatial bookmarks.

...

To pan the map:

1. Within the map Map view, click and hold the left mouse button and drag the mouse and release.

...

1. In the Contents pane, right-click the COH_HISTORIC_SITESLANDMARKSDISTRICTS layer name and select Zoom To Layer.

...

1. On the Map tab, in the the Navigate group, click the Bookmarks button and select New Bookmark....
   
   
   
   
2. In the 'Create Bookmark' window, for 'Name:', type "Houston Historic Districts" and click OK.
3. To test the bookmark, use panning and zooming to change the extent of the map.
4. Again, click the Bookmarks button and this time select the Houston Historic Districts bookmark to return to that extent.

1. On the Map tab, in the Selection group, click the Select button.
   
   
   
   
2. In the map Map view, click on any historic district to select it.

...

1. Drag a box to select multiple historic districts. This will also select any historic sites/landmarks your box intersects.
2. Hold down Shift and click any non-selected historic district to add additional non-adjacent historic districts to the selection.
3. Hold down Ctrl and click any selected historic district to deselect.

...

A table view now appears docked beneath your map Map view. Each row, or record, in your table corresponds to exactly one historic district polygon on the map. Each column, or field, in your table represents a variable describing the historic districts.

...

Within the Spatial Reference section, notice that the geographic coordinate system is GCS WGS 1984 and that no projected coordinate system is listed. Therefore, the layer is unprojected, meaning the data coordinates are located on the three-dimensional surface of the globe and you can see the Angular Unit is listed as Degrees (or decimal degrees.) Therefore, the Shape_Length field is displaying decimal degrees and the Shape_Area field is displaying square decimal degrees, which is why the numbers are so low. Before measuring distance or area, the data layer should be projected onto a two-dimensional surface. The resulting projection will have a Linear Unit, such as feet or meters. The process of projecting is further covered in the Introduction to Coordinate Systems and Projections course.

1. In the ribbon, click the Map tab.
2. In the Selection group, click the Select By Attributes button to open the Select Layer By Attribute tool in the Geoprocessing pane.
   
   
   
   
3. In the Geoprocessing pane, ensure the COH_HISTORIC_DISTRICTS layers is selected in the 'Layer Name or Table View' input.
4. Click the Add Clause button.
5. Use the drop-down menus to build the following expression: NAME is Equal to 'Main Street/Market Square Historic District' and click the Add button.
6. Ensure your Geoprocessing pane appears similar identical to that below and click Run. You will see that one historic district, named "Main Street/Market Square Historic District" is now selected.
   
   
7. On the the Map tab, in the Selection group, click the Clear button to clear the selected features.

...

1. In the Selection group, click the Select By Location button to open the Select Layer By Attribute tool in the Geoprocessing pane. 
   
   
   
   

2. Select features from COH_HISTORIC_DISTRICTS that intersect Major_Rivers. Ensure your Geoprocessing pane appears similar identical to that below and click Run.

3. 
   

Exporting Selected Features  

To create a new layer with just our historic district of interest we need to export this selected feature.

1. In the Contents paneIn the Contents pane, right-click the COH_HISTORIC_DISTRICTS layer name and select Data > Export Features.
2. In the Geoprocessing pane, click the 'Output Feature Class' field to edit the name. Replace Replace "COH_HISTORIC_DISTRICTS_CopyF" with "MainStreet_MarketSquare". Ensure that you leave everything in the file path through Intro_Part1.gdb\. Click Run.

3. On the the Map tab, in the Selection group, click the Clear button to clear the selected features.

Now we will create a map of the historic district at risk of flooding due to proximity of a river. We could continue to do our mapping within the existing map, but, since we are now focusing on different thematic layers in a different geographic extent, this could be a good time to create a second map within our project.
