You will now add a feature class to a new map that depicts all of the land parcels in downtown Houston. This feature class was originally obtained from the Harris County Appraisal District (HCAD) Public Data GIS website at http://pdata.hcad.org/GIS/index.html. The original parcels shapefile contained all of the parcels in Harris County, but working with such a large file can be time consuming, so, for the purposes of this tutorial, the layer was clipped to contain only those parcels in downtown Houston.

...

The HCAD_NUM field contains the unique 13-digit HCAD account number for each parcel. You are also provided with the owner name and address for each parcel, but no other information. Fortunately, a tremendous amount of information about the parcels can be obtained from HCAD in standalone tabular format. In this case, you would like to know the particular land use for each parcel, such as residential, commercial, or industrial. This information is contained in a separate Land table, which was originally obtained from the HCAD Public Data Download website at the the http://pdata.hcad.org/download/index.html.

Joining Tabular Data

Now that you have examined all of the data tablesNow that you have examined all of the data tables, you are ready to join them all together. It is possible to join tables together in any order, but you will want to join both land use tables to the back of your DowntownParcels attribute table, so that you can later symbolize the parcels based on their land use. You will first join the Land table to the DowntownParcels feature class using the unique HCAD account number as the common join field.

  1. In the Contents pane, right-click the DowntownParcels layer name and select Joins and Relates > Add Join.

The Geoprocessing pane should open on the right in a new tab overlaying the Catalog paneA tool titled Add Join should pop up on the screen. In the Add Join tool, notice that 'Layer Name or Input Table View' is already set to the DowntownParcels layer, since that was the layer used to open the tool.

  1. For ‘Input Join Field’, use the drop-down menu to to select the HCAD_NUM field.
  2. For ‘Join Table’, use the drop-down menu to select the Land table.
  3. For ‘Output Join ‘Join Field’, use the drop-down menu to to select the ACCOUNT field.
  4. Ensure that the ‘Add Join' tool settings match those shown below and click Run  OK at the bottom of the Geoprocessing panetool.

  4. Click RunOK.
  5. Once the join is complete, scroll to the far right in the DowntownParcels attribute table.

...

In order to successfully perform a join, the corresponding join fields in both tables must be of the same field type. Unlike in Excel, you cannot simply convert an existing field from one type to another. Instead, you must create a new field of the correct field type and copy the data over into the new field. In this case, you will convert the LAND_USE_C field in the Land table to a text field type to match the text field type used in the LandUseCode_LookupTable table.

  1. In the Catalog Contents pane, right-click the Land table and select Design > Fields Open to open the attribute table.
  2. At the top right of the Land table view, click the collapsed menu icon (or hamburger button) and select Fields View.
  3. At the bottom of the attribute table, click ‘Click here to add bottom of the attribute table, click ‘Click here to add a new field.’
  4. For the new ‘Field Name’, type “LAND_USE_C_Text” and press Enter.
  5. For ‘Data Type’, click once to highlight Long and activate the field and then click Long a second time and use the drop-down menu to select Text instead.
  6. On the ribbon, the Fields tab should now be active. In the Changes group on the far rightManage Edits group, click the Save button to save the changes to the design of the Land table fields.

  1. In the 'Fields' list under the 'Expression' subsection of the tool, double-click the LAND_USE_C field.

Notice that the box below now reads LAND_USE_C_Text = !LAND_USE_C!, as shown below. This statement will copy all of the content from the original LAND_USE_C integer field into the new LAND_USE_C_Text text field.

  1. Click Run OK.

In the Land table view, ensure that the land use codes have, indeed, been copied over into the new LAND_USE_C_Text field and that they are left-aligned as text, rather than right-aligned as numbers.

At this point your table has everything you need and nothing extra (except for a duplicate state name field, which will be deleted shortly), but it is always recommended to clear all formatting and programming before bringing the Excel file into ArcGIS. In addition, columns B, G, and H currently have To get rid formulas, which need to be converted to text before ArcGIS can read them properly. To get rid of all formatting and programmingformulas, you will copy all of the data into a new blank worksheet as text.

Now you will return to ArcGIS to map the land cover data by state.

  1. Maximize ArcGIS Pro.

Because you already have the map document from the prior exercise set up with the correct default database, you will use this map document as a template, rather than starting a new one.

  1. At the bottom of the right pane, click the Catalog tab.
  2. In the Catalog pane, within the Tabular geodatabase, right-click the US_States feature class and select Add To Click the Insert menu and select New Map.

This creates a new map in the project in which you will map your state land cover data. You will now save this map with a different name, so as to distinguish this exercise from the last one.

  1. In the Catalog pane, double-click the expand the Maps folder and .
  2. Rightright-click Map2 Map1 and select Rename.
  3. Select Rename and change the File name to “USLandCover”.

You will now explore the state data.

  1. Type “US Land Cover” and press Enter.

.

  1. In the Contents pane, right-click the US_States layer and select Attribute Table.

Examine the attribute table for the US_States layer and notice that the field containing the state names is “NAME10”.

  1. Close the attribute US_States table view.
  2. In the Analysis tabAt the bottom of the right pane, click the Tools icon Geoprocessing tab.
  3. At the top left of the Geoprocessing pane, click the Back button.
  4. In the 'Find Tools' search bar In the Geoprocessing pane on the right, click within the Find Tools search bar and type "excel".
  5. Click Excel to Table (Conversion Tools).
  6. For the Input Excel file, click the Browse button to the right and navigate to the TabularTutorialData. Select USLandCover.your Tabular folder on the Desktop. Select USLandCover.xlsx and click Open.

It will take a moment for the table to load. Note that the 'Sheet' drop-down menu has appeared, and the default sheet selected is 11s0365is now populated and Sheet1 is selected by default. Because a single Excel file can have multiple worksheets and each worksheet is treated in ArcGIS as a separate table, you must always specify which specific worksheet you want to use.

  1. Rename the Output Table "US_LandCover".
  2. Make sure Ensure the Geoprocessing pane looks like the picture appears as shown below and then click Run at .

  3. At the bottom right corner of the pane.

 

  1. In the Catalog right pane, double-click the Folders folder to show the TabularTutorialData folder Catalog tab.
  2. In Within the Contents pane Tabular geodatabase, right-click the newly created US_LandCover standalone table and select Open Add to Current Map.

Examine the US_LandCover table and notice that the field containing the state names is “State”. Using your knowledge from the first exercise, try to join the US_LandCover worksheet to the US_States feature class and symbolize the states by both the percent developed land and the percent forest land.  If you get stuck, ask for help.
