2. Configure ET+ ArcGIS and Excel

Now that the project site’s spatial data is ready, we can begin to set up the ET Tool.

As a reminder, the only two necessary fields in your shapefile are Existing Land Use (EX_LU) and Total Acreage (TOT_ACRE). So, right-click on those other fields and delete them.





Also, it will be helpful to remove all of the shapefiles and start with a blank ArcMap.

GEODATABASE

  1. At the top of the menu, navigate to the Catalog button. 
       

  2. On the right, ArcCatalog will appear. Navigate to your working folder and right-click on the name. Choose New> File Geodatabase. Name the File Geodatabase “ET_Scenario_Project”.  



               
  3. Now import the Site_Polygrid into the geodatabase. This will be your scenario layer. In ArcCatalog, right-click on ET_Scenario_Project and select Import> Feature Class (single)...  



  4. In the Feature Class to Feature Class Box, under Input Features select “Site_Polygrid” and under Output Feature Class name it “ET_Vision1”. Click OK. 

  5. Eventually, we will have as many feature classes as scenarios, but right now we will stick with one.

ET TOOL

  1. Ensure you have the Envision Tomorrow Plug-in. At the top of the menu, select Customize and choose Toolbars>Envision Tomorrow. 



  2. A two button toolbar will show up with ET Project Setup and ET Paint Tool. Click ET Paint Tool. In the ENVISION PAINT TOOLS menu, click File>Open Envision File Geodatabase and select the newly created File Geodatabase "ET_Scenario_Project", and click Add.

  3. Next, it will prompt you for an Excel Workbook, navigate to your ET Workbook (which can be found in the 2_ConfigureET folder) and select Open.  




  4. Once you are connected, and a few minutes have passed, development types will be loaded along with a color palette:




  5. Next you will be prompted to Define Scenario Layers. Click OK. 


    In the ENVISION PAINT TOOLS menu, select File> Define Scenario Layer and use the dropdown menu to make Scenario 1 equal ET_Vision1.  



The tool is almost ready. We now need to populate the newly created fields: VAC_ACRE, DEVD_ACRE, and CONSTRAINED_ACRE...
