When you create a radius map (or buffer map), you place a radius around your data points based on distance. A radius measures the length between the center of a circle and a point on its perimeter. These maps help identify and analyze all data points within that defined area.
Radius maps are powerful way to use interactive mapping software that helps businesses with smarter territory planning. They clearly show which prospects, customers, or leads fall within a certain distance. They also show drive time from a central location, such as a store or a sales rep's base.
Here's why radius maps matter in business:
- Allow you to respond faster by assigning the right reps to the right areas
- Help businesses optimize routes
- Identify potential customers or target areas for marketing campaigns based on proximity to their location
- Help identify coverage gaps
- Prioritize outreach in high-potential zones
- Support location-based decision-making for events, promotions, or service delivery
- Show customer locations within a few miles of each store
- Model service coverage capacity for a given radius
- Identify gaps in coverage that new sites could fill
There are two ways to draw a radius on a map. One is distance-based and the other is based on driving time. Let’s take a closer look at the differences between these two types.
Distance-based Radius
The simplest type: a perfect circle showing all points within a specified distance (e.g., 10 miles or 50 km). It’s ideal for understanding customer density, running direct mail campaigns, or seeing how far your brand can reach from a single point. The map radius helps businesses understand reach and proximity from a central location.
Drive-time Radius
Instead of straight-line distance, this map shows areas reachable within a set driving time, like 30 minutes from a warehouse. It accounts for road networks, traffic, and real travel time. It offers a more realistic view of sales route planning or delivery logistics for sales reps, deliveries, or service teams.
The following steps will guide you through the process of how to draw a radius on a map. Once you’ve decided what your objectives are, using the tool is a cinch. You can plot buffers, set appropriate parameters, and even customize your map.
Step 1
Choose a Tool
Distance-Based Tools
Use a distance-based radius map when:
- You need a quick, fixed-radius analysis from a central point (e.g., 10 miles around a store)
- Your business operates in rural or low-traffic areas where travel time doesn’t vary much
- You want to evaluate coverage areas for physical assets like cell towers, warehouses, or billboards
Drive-Time Tools
Use a driving radius map when:
- Travel time matters more than distance, such as for sales reps, delivery drivers, or service technicians
- You operate in urban or congested areas where traffic significantly impacts accessibility
- You're planning service-level agreements or customer visit schedules based on how far someone can drive in, say, 15 or 30 minutes
Step 2
Draw the Radius
You can create a radius on a map from any point. To get the most value from the radius analysis tool, you'll need to prepare at least two data sets to draw a radius on a map. For example, the sales rep's location could be the center point, and the customer's address could be the points in the circle surrounding that specific radius.
Drawing a Circle
- Upload your data (e.g., reps and customers) and select Analyze
- Select Radius
- Choose a distance (e.g., 10 miles), select your center points and surrounding points, then hit Complete
- A circle appears showing all customers within that set radius, which is perfect for proximity mapping techniques that harness the power of geography to unlock spatial insights
Drawing a Drive-Time Area
- Upload your data (e.g., reps and customers) and select Analyze
- Select Drive Time
- Enter a drive-time length (e.g., 30 minutes), then hit Complete
- You'll see a real-world travel zone based on roads and traffic, which is ideal for planning routes and coverage realistically
Step 3
Customize and Use
After reviewing your map, you can expand the radii by clicking "Edit" in the control panel (under "Analyze"). It returns to the settings screen where you can change the radius map by distance or any other variables (including checking the Outside Results box to see customers outside a sales rep's radius). Once you've changed the settings, click Complete to draw your radius on the map again.
Map Styling
Map styling refers to the many ways you can style your map to highlight your data and enhance the understanding of your findings. eSpatial offers a range of styling options that help you turn a simple map into a visually rich, business-ready tool. Here's what you can do:
- Colors & transparency: Change fill colors and adjust transparency to highlight zones without hiding other data
- Borders & labels: Customize boundary lines and add labels to clearly identify each radius or drive-time area
- Data layering: Overlay customer, lead, or competitor data to see distribution patterns within your radius
- Pins & symbols: Use different colors, shapes, or icons for pins to represent various account types or sales priorities
- Map backgrounds: Choose from light, dark, terrain, or satellite basemaps to match the context of your analysis or presentation
Business Applications
If you're looking for powerful mapping software for business insights, our Radius Maps are a game-changer. You can analyze a multitude of variables affecting your sales and business processes, helping you make better decisions. Here are just a few of the numerous mapping possibilities:
- Real estate: Real estate professionals can use it to evaluate properties' proximity to amenities like parks, schools, or shopping centers
- Emergency services: Emergency responders can utilize it to assess the coverage area of fire stations, police stations, or medical facilities
- E-commerce businesses: Online retailers can analyze order data and create delivery radius maps around key fulfillment centers to determine whether customers are getting fast deliveries and where new micro-fulfillment centers could help
Radius maps aren't just one-off visuals — they fit seamlessly into everyday business tasks. Sales managers can design balanced territories or spot underserved areas. Marketers can target campaigns by location, while operations teams plan site visits or deliveries more efficiently.
