Map intermodal rail and truck facilities in Iowa
In addition to operating rail lines, railway companies run intermodal facilities along the lines. These are facilities where cargo can be transferred between modes of transport—from a train to a truck, for example. This section explains how to find and place these facilities on the map, and filter for the types and location of interest. Locating intermodal facilities in Iowa will allow the railway company to prepare to expand its business network near these facilities.
Add and filter data
First, you will search for and apply a feature service to your map in ArcGIS Online. This feature service will add a layer to your map depicting all intermodal freight facilities in the United States.
- Sign in to your ArcGIS organizational account.

Suitability analysis allows you to decide which factors are most important to you and evaluate and rank sites on a map according to these criteria. You mapped the intermodal rail and truck facilities in Iowa. Next, you'll select criteria and rank the facilities to understand which facilities present the best business opportunities for the rail line.
Perform a suitability analysis
In ArcGIS Business Analyst, suitability analysis allows you to decide which factors are most important to you, then evaluate and rank sites on a map according to these criteria. You have mapped the intermodal rail and truck facilities in Iowa. Now you will select criteria and rank the facilities to understand which facilities present the best business opportunities for the rail line.
Define sites for analysis
To start your suitability analysis of intermodal facilities in Iowa, you first need to identify these facilities as sites for analysis. Sites are areas of interest that you can use to gather representative demographics and other data. In this tutorial, you'll create sites using a 30-minute drive time. Defining the sites as 30-minute drive times around each intermodal facility will allow you to find what other businesses are close enough to these existing sites to become clients.
- On the ribbon, click Run analysis and choose Suitability analysis.
The Suitability analysis welcome pane may appear, outlining the three steps in the suitability analysis workflow.
- If necessary, in the Suitability analysis pane, click Get started.
Note:
To opt out of seeing the welcome panel in the future, you can check the Skip this step in the future box.
- For Select location type, click Features on the map.
- Click Next.
The pane lists all 73 intermodal facilities in Iowa.
- At the bottom of the pane, for Create buffers around selected points, click Drive time.
By default, there are three fields for calculating drive time. The three fields indicate the number of buffers around each site that will be created. The default values for these buffers are 5, 10, and 15 minutes. You just want to know about the region surrounding each site within a 30-minute drive.
- In the first box, delete the value 5 and type 30. Delete the other two values and leave them blank.
- Click Create sites.
The 30-minute drive features appear on the map for each site. These shapes overlap where sites occur close to each other.
- In the Suitability analysis pane, click Next.
You have now set up the regions around intermodal facilities as sites for a suitability analysis.
In the next section, you will continue the suitability analysis workflow, selecting and weighting your analysis criteria.
Select criteria
Suitability analysis determines the best sites for something, based on criteria that you select. In this case, you want to know which intermodal facilities present the best business opportunities for the railway, based on the businesses nearby that are likely to use intermodal facilities for freight shipping, as well as the demographic information of the surrounding area. You will select your criteria accordingly.
- In the Suitability analysis pane, click Select Criteria and choose Add variables from data browser.
The Data browser window appears. You will now select criteria that reflect the businesses, population, and spending behaviors near each intermodal facility.
- In the Data browser window, browse the categories and click Business.
The Business category opens. Several popular variables are displayed, as well as options to find more data. You'll find potential client businesses by searching for NAICS codes.
- At the top of the window, click Industry by NAICS Code to filter the variables.
NAICS, or North American Industry Classification System, codes are numerical identifiers that classify types of businesses. You'll be using NAICS codes to find types of businesses that may be interested in using the railway’s intermodal facilities.
Tip:
You will notice that the Data Browser shows a browsing trail at the top of the window. This list shows the path you took to get to the current page. You can select any part of the trail to return to it. This is the best way to navigate the Data Browser.
- In the variables list, scroll a little more than halfway down and select each of the following variables:
- 2024 Agric/Forestry/Fish/Hunting (NAICS11) Sales
- 2024 Mining (NAICS21) Sales
- 2024 Wholesale Trade (NAICS42) Sales
- 2024 Transportation/Warehouse (NAICS48-49) Sales
Note:
Data is periodically updated. Use the latest data available.
As you select each variable, they are added to the Selected variables list.
- At the top of the window, click Selected variables.
The four variables you selected are listed.
- Click Explore to return to the Standard variables list.
The four variables you selected remain in Selected variables list. Next, you will add more criteria for your analysis. This time, you will add information about the number of people who live near Iowa’s intermodal facilities.
- Under Categories, click Population. Under Popular variables, select 2024 Total Population (Esri).
You now have five variables in your Selected variables list.
- Click Explore to return to the main search page.
You will now add information about the likely spending behaviors of the population near the intermodal facilities.
The economic benefits of rail freight compared to transportation by road are significant. For freight companies, there is a large demand to ship cars over the rail. It is more cost-effective and fuel-efficient to ship large quantities of newly manufactured cars on a freight train than on interstate highways using trucks.
To model this demand, you'll select variables that show areas that might be receiving large shipments of new vehicles because of regionally high demand from auto dealers.
- Under Categories, click Behaviors.
- For Filter by, click the drop-down arrow for Keyword and type leased.
The variable list updates based on the keyword search results.
- Check the following variables:
- 2024 HH Bought/Leased Most Recent Vehicle 1-2 Yrs Ago
- 2024 HH Bought/Leased Most Recent Vehicle 3-4 Yrs Ago
You now have seven variables in your Selected variables list.
- At the bottom of the Data browser window, click Apply.
A suitability analysis is calculated, coloring the sites matching the most criteria in shades of red. Each of the variables is equally weighted, so each of the variables you added counts equally in determining suitability.
Note:
By default, the results appear as points, but later you will display the suitability results as areas.
In the next section, you will adjust the weights of the variables to reflect what is most important to you for ranking sites in the analysis.
Weight criteria
By default, the suitability analysis workflow assigns equal weight to all your criteria, with all criteria adding up to 100. The weights of the various criteria indicate how strongly each variable affects each site’s final score in the analysis. By increasing the weight of certain variables, you specify which factors are most important to you in ranking sites.
- In the Suitability analysis pane, scroll to the Weighting section and click Adjust weights.
- In the Adjust weights window, for 2024 Agric/Forestry/Fish/Hunt Sales (NAICS), change the variable’s weight to 25 and press Enter.
he other variables’ weights have been automatically adjusted, evenly distributing the remainder of the pie (each will now read 12.5 percent). The site rankings on the map adjust to match.
- For 2024 Agric/Forestry/Fish/Hunt Sales (NAICS), click the lock button.
Locking the percentage prevents changes to this variable’s weight, either accidentally, or by changing the weights for other variables.
- Adjust the following variables' weights, locking each after changing it:
- 2024 Mining Sales (NAICS): 20
- 2024 Wholesale Trade Sales (NAICS): 15
- 2024 Transportation/Warehouse Sales (NAICS): 20
You'll leave the last three variables as the weights have automatically adjusted (each is now weighted 6.67%).
- Click Done.
- In the Suitability analysis pane, for Style options, click Areas.
The map updates based on the adjusted weights.
You've now weighted the variables so that your suitability analysis reflects the criteria that are most important to you. In this case, you are most interested in intermodal facilities with agricultural businesses nearby. The proximity of mining, transportation and warehouse, and wholesale trade businesses are also important to you to varying, lesser degrees. Of least importance among your criteria are the population and car ownership among people in the vicinity.
The United States (particularly Midwestern states such as Iowa) is a major producer of grain. Trains are very efficient for moving large quantities of agricultural products such as grain across long distances. Similarly, industries that ship in massive bulk quantities make heavy use of railways because, in addition to efficiency, railway freight transport ensures safety when dealing with potentially hazardous materials such as fertilizer.
View ranked sites and export results
You have conducted your suitability analysis, using criteria relevant to the railway in its goal of expanding its business network near intermodal facilities. Now you can use Business Analyst to refine your results and delve deeper into the analysis.
- In the Results pane, click the Table button.
- If necessary, resize the table vertically so you can see more records, while keeping the areas in Iowa visible.
Note:
Suitability scores are calculated on a scale of 0 to 1. This means that a suitability score of 0.31 reflects a 31 percent suitability rating.
To make the map easier to see, you'll change the symbols from the drive time polygons.
- In the table, point to the first record.
Notice that when you point to a record in the table, the corresponding site will be highlighted on the map. You can also point to a site on the map to show a pop-up with name, suitability score, and rank among the sites.
- On the map, point to the same site.
A pop-up appears containing information about the site.
- In the Style section, for Map symbol, click Points.
The polygons on the map will change back to simple circular markers for each site, displaying the site’s rank in the analysis. You can also filter the results to only show the most suitable.
- In the Legend section, click Filter results.
The Filter results pane appears. You can filter by rank, selecting a desired number of top or bottom results. In this case, you'll filter by score.
- If necessary, click Filter by score and set the lower value to 0.5 and press Enter.
The map now shows only the sites that scored 50 percent or higher in the suitability analysis.
Your map and attribute table show 18 sites with suitability scores of 50 percent or higher. To share this information with interested stakeholders at the railway, you can export the attribute table.
- In the Results pane, click Export to Excel.
- In the Export to Excel window, click Export.
Your browser downloads a Microsoft Excel file named Suitability analysis. When you open the file, you will see your filtered suitability analysis results as a table. You can also export the suitability analysis as a new layer in your project, using the Export dialog box. This is helpful if you want to return to this analysis later.
In this tutorial, you learned how to find and add a feature service to a map in ArcGIS Online, filter the feature service, and perform a suitability analysis in Business Analyst. Using the results of the suitability analysis, the railway can decide which intermodal facilities present the best opportunities to expand its business network. By identifying sites located near a large number of businesses that might use intermodal facilities, the railway is now prepared to reach out to businesses in these areas.
