ArcGIS StoryMaps

What is an express map and why should you use one?

Where stories happen matters. We take the “maps” part of “StoryMaps” very seriously. Geography isn’t merely a passive stage upon which things happen. It shapes our stories. It often explains those stories. Place matters and without it your readers may be missing the whole story. So, even if you’ve never had any cartographic or GIS training, we want you to be able to include maps in your stories—that’s why we created express maps within the ArcGIS StoryMaps builder.

Showing the generalized movement of troops onto the five sectors of Normandy Beach are central to this story. The red pins show locations of important battles in WWII.

Express maps help you to quickly create and embed simple locator and distribution maps in your narratives. Most stories happen somewhere and they usually need one or more simple maps to help readers orient themselves. If you’re not sure your audience knows where a place is, use an express map. Need to show the location of new store openings, and their business hours, in your hometown? Or how things are moving around, whether across campus or around the globe? Or the boundaries of a study area or region? These are all great ways to use express maps. Our goal was to make cartography as simple as possible so anyone can add focused maps at the right time.

Add rich content to your pop-ups to help bring places to life. This story about giraffe species in Africa includes photos and descriptions in the pop-ups, but you can add links to them too.

The anatomy of express maps

There are only four components to an express map:

  1. The basemap or “canvas” of the map, which is already crafted for you;
  2. The drawn features you add to the map yourself to represent geographic information (like points, lines, or areas);
  3. The map pop-ups attached to those features, complete with any relevant details you supply; and
  4. The annotations you add to provide more context (like text or arrows).

Express maps use the overall theme of the your story. This is a big deal because it means—without doing any extra work—your maps always harmonize with the rest of your narrative by using the same accent colors, fonts, and so on. Even better, if you change your story theme later on, the express map will update too.

The topographic basemap perfectly complements a story about hikes in Acadia National Park. These generalized routes are traced directly on top of the basemap sidestepping the need to find and import hiking trail data. Tip: Zoom in when tracing to make it easier as you go.

Though express maps have great default settings, feel free to customize both the basemap and the accent colors. Basemaps are the most complicated part of the map and having those ready-to-go is a big time saver. They also really set the overall personality of the map so be sure to test drive a few.

It’s worth nothing that different basemaps also contain different kinds of content, and emphasize different kinds of things. Some might emphasize things like terrain while other focus on human boundaries and roads. Some are colorful, some are muted. We always offer three basemap choices in the map settings panel that harmonize well with the overall story theme or style.

Express maps are all about the drawing tools

When creating an express map, you’ll notice a variety of drawing tools available to you in the map designer’s toolbar. This is the heart of the express map authoring process: Use it to add points, lines or areas to your map as needed. It also includes helpful annotation tools for labeling the map directly, or including arrows that can be curved to fit your exact needs.

The things that you draw will automatically appear in the layers panel on the left side of the map. Your readers won’t see this panel, it is there so you can rename the features on the map, fill-out your pop-ups, change the color of points, lines or areas, or delete them. Note that annotations and arrows do not appear as line items in the map panel (or the map legend, which your readers see) since they are self-explanatory.

Pro Tip: You have the option to drag out leader lines from the annotation text by grabbing the handles at the top or bottom of the text box. Even if you reposition the text later, the lines will self-adjust and look great.

When can express maps be useful?

There are a few different instances where my teammates and I think express maps really come in handy:

Here’s a closer look at each one of these, complete with examples.

 

Add a small locator map

Simple locator maps should be compact and work at a glance. This story of Kyrgystan’s celestial mountainshits the ground running with a locator map to help us understand where this narrative takes place. Bonus points for using the float size option so the story wraps around the locator.

 

Draw important areas

Not all locators need to be pins; sometimes we want to show regions or areas. Think of a news story showing areas that need to be evacuated, or ecological study areas, or sales territories. This can be especially hard when the areas aren’t standard boundaries like states or counties. Luckily, in express maps you can use the area tool to outline your region one vertex at a time, or draw more fluidly with the freehand area tool.

Using either the area tool or the freehand tool to draw areas. Here I drew an area to represent a fictional study area .

Show a route or sequence of events

Use numbered points in combination with the arrows to show a travel itinerary, a sequence of events, or the route of a delivery vehicle (for just a few ideas). Made a mistake? No worries, just click and drag any of the numbered points and move them. Or even delete one; the remaining numbers will re-order without missing a beat.

A custom accent color helps to set the mood of the map and ensures the sequence of stops are the focus.

Sketch what’s inside your head

Many times I find it’s easier to explain my thoughts by sketching on a paper map and annotating it with arrows and text. We aimed to bring that same simplicity to the drawing and annotation tools in express maps. There are times when maps need to be made with millimeter precision, or include an incredible amount of detail—these are scenarios where ArcGIS Online and Pro excel. But not all of our maps need that level detail or complexity. Often, generalized maps will work better on small screens and communicate the salient bits of story quickly. This is where express maps shine.

This express maps shows areas of Romania which are heavily deforested. At this scale the generalization of these areas is entirely appropriate because it doesn’t oversell the data. As a rule, I always try to match the scale and details of the maps to the nature of the data, and critically, to the needs of the audience.

Let’s get going

The best way to learn about express maps is to jump in and start playing. If it’s your first time making one, the StoryMaps builder has some onboarding material to get you oriented. But don’t be afraid to experiment and try things because (best of all!) we’ve built undo/redo into express maps so you can’t get into trouble. And if you don’t like what you’ve made, you can always delete the map from the story and try again.
