First, you'll create a map in ArcGIS Online that shows block groups in Manhattan where the demand for electronics stores exceeds the supply. You'll also share your map in a group so you can access it later in Adobe Illustrator using ArcGIS Maps for Adobe Creative Cloud.
Define the study area
Your map's study area is the island of Manhattan in New York City. You'll start a new ArcGIS Online map and navigate to the proper location.
- Sign in to your ArcGIS organizational account.
If you don't have an organizational account, you can sign up for an ArcGIS free trial.
- At the top of your organization home page, click Map.
If you're in a new session, a new map opens with a basemap, which provides geographic context to your data layers.
If you're not in a new session, an existing map might open instead. In the upper right corner of the page, click New Map and choose Create New Map.
- In the search box at the upper right of the map, type Manhattan. In the list of results, click Manhattan, NY, USA.
The map zooms to southern Manhattan, New York.
- Close the Search result pop-up.
The basemap depicts some features of the area, including roads, bridges, buildings, and parks. However, the current zoom extent shows only the southern part of Manhattan Island.
- Zoom out and pan the map until you can see most or all of the island.
Manhattan Island's northeast boundary is defined by the Harlem River.
Add a Living Atlas layer
Next, you'll add data about the supply and demand of electronics stores in the area. You'll access this data through the ArcGIS Living Atlas of the World, which contains curated geographic information from Esri and its partners.
- On the ribbon, click Add and choose Browse Living Atlas Layers.
A window appears, showing a list of Living Atlas layers. You can filter the layers based on categories to narrow the available options.
If you don't have access to premium data, you can select Search for Layers, expand the category and select ArcGIS Online and add the feature layer 2017 USA Electronics Store Market Opportunity owned by Learn_ArcGIS.
You can skip to step 4.
- In the search box, type 2018 USA Electronics Stores and press Enter.
The search returns one result.
- Under 2018 USA Electronics Stores, click Add.
The layer is added to both the map and the Contents pane.
- In the search window, click the Back arrow to return to the Contents pane.
The layer you added has many features, symbolized as either brown or green. Green areas are places where the demand for electronics stores exceeds supply, while brown areas are places where supply exceeds demand. Your employer is interested in green areas where demand exceeds supply.
Expand the legend and notice the categories for each group. Notice that areas with a high market opportunity are shaded with a dark green, while those that have a low market opportunity are a brown color.
- Click any green feature to open its pop-up.
The pop-up displays additional information about the feature. First, the pop-up title shows the feature's name. The example image feature is a New York block group designated by a number.
The layer you added contains data for many different scales, including country, state, census tract, and block group. Depending on your zoom extent, the type of feature displayed on the map may differ.
If your pop-up title does not indicate a block group, zoom in until block groups appear on the map.
Next, the pop-up shows the number of electronic and appliance stores in the area, as well as total sales (supply) and sales potential (demand). Based on these numbers, each feature also has a Market Opportunity number, also known as a Leakage/Surplus Factor, on a scale from 100 to -100. While these numbers may seem complicated, all you need to know for the purposes of this lesson is that positive Leakage/Surplus Factors indicate that demand exceeds supply, while negative values indicate the opposite.
For instance, the example image has a Leakage/Surplus Factor of 100, the maximum possible number. It has this number because there are no electronics stores in the area, so demand exceeds supply by 100 percent.
- Close the pop-up.
Filter the layer
The goal of your map is to show block groups where demand for electronics stores exceeds supply. While your current map shows those areas, it also shows areas where supply exceeds demand and where supply and demand are close to equal. You'll filter the layer to show only areas where there is significantly more demand than supply.
- In the Contents pane, click the 2018 USA Electronics Stores Market Opportunity layer to expand it.
As mentioned previously, the layer contains data for many different scales. The scales that are not currently active on the map are grayed out. Only Block Group, the smallest scale, is active.
If you added the feature layer from Learn_ArcGIS, you won't see the data from different scales. The feature layer is at the block group level.
- Point to the Block Group category and click the Filter button.
For the feature layer, click the Filter button.
The simplest way to filter your layer would be to only display features with a Leakage/Surplus Factor greater than 0. However, a positive Leakage/Surplus Factor close to 0 indicates that supply and demand are fairly close. Showing these areas wouldn't be particularly helpful for your company's upper management, which wants to capitalize on areas where demand significantly exceeds supply. You'll create a filter to display only features that have a Leakage/Surplus Factor of at least 20.
- In the filter, for the first box, choose 2017 Leakage/Surplus Factor: Electronics & Appliance Stores (NAICS 4431).
If you're using the layer from Learn_ArcGIS, choose Electronics/Appliances Stores (4431):L/S.
- For the second box, choose is greater than. For the third box, type 19.
Note:Display features in the layer that match the following expression.
Overall, your filter expression will display features with a Leakage/Surplus Factor greater than 19.
- Click Apply Filter.
Your map now displays only census blocks where demand significantly exceeds supply. Most of these census blocks are on the eastern and northern part of Manhattan Island.
If it doesn't look like your filter changed anything on the map, zoom in until only block groups are displayed. Your filter was only applied to block groups, so if your map displays census tracts or ZIP Codes, you won't see any changes.
You've created a map with the data you need. Next, you'll save the map.
- On the ribbon, click Save and choose Save As.
- In the Save Map window, add the following information:
- Title: Demand Exceeds Supply (You may want to add your name or initials to the title to more easily identify your map later.)
- Categories: People/Income
- Tags: Manhattan, New York City, Electronics Stores
- Summary: Areas in Manhattan where demand exceeds supply for electronics stores
- Click Save Map.
Create a group
Later, you'll access your map using Adobe Creative Cloud. But first, you must add it to a group with a specific tag that makes it searchable within the extension. That tag is M4CC (an abbreviation of Maps for Creative Cloud).
- Next to the name of your map, click Home and choose Groups.
The Groups page contains a list of your existing groups and options for creating a new group. Groups are collections of content that you can manage as needed. You'll create a new group with the appropriate tag.
- Click Create New Group.
You may want to add your name or initials to the title to more easily identify your map later.
- For Group Name, type Demand Exceeds Supply.
- For Summary, type This group contains a map that shows census blocks in Manhattan where demand exceeds supply for electronics stores.
- For Tags, type the abbreviation M4CC.
You must type this exact tag or you won't be able to access the map in Illustrator.
You can also change settings that determine who can view or contribute to the group, but for now, the default settings are sufficient.
- Click Create Group.
Next, you'll add your map to the group.
- On the ribbon at the top of the page, click Content. In your Content page, check the box next to your Demand Exceeds Supply map.
- Click Share. If necessary, choose Access.
If you're a member of a group with the item update capability enabled, clicking Share displays a menu with two options. You must indicate whether you want group members to be able to update the item you're sharing. For more information, see Share items with a group.
- In the Share window, under These groups, check the Demand Exceeds Supply box to share the map with your group.
- Click OK.
Your map is created and shared in a group with the proper tagging structure. In the next lesson, you'll open your map in Adobe Illustrator using ArcGIS Maps for Adobe Creative Cloud. Then you'll add more data and design your map to give it a professional appearance that you can present to your company's upper management.
