Visualize Trends With a Heat Map Generator


The complete playbook for heat mapping your data.

What is a Heat Map?


A heat map turns raw locations into a colour-coded story.

  • Red (Warm): High density. Your hot spots
  • Blue (Cool): Low density. Areas to investigate

Analysts, sales, and ops teams use this to spot hidden trends fast. You get actionable insights without the spreadsheet fatigue.

  • Decide quicker: Move from analysis to action instantly
  • Grow faster: Use the eSpatial generator to drive revenue and streamline ops

What is a heat map generator?

Map your reach. Instantly. Turn spreadsheet rows into geographic insights with a single click in mapping software. You need to see where your business lives. Visualise customers, reps, and assets to spot density and coverage gaps in seconds.

The Edge

  • Visualise data: Map customers, franchises, or delivery centres
  • Spot density: Identify hot spots and cold zones immediately
  • Optimize territories: Analyse performance by post codes or region

Two Types of Geographic Heat Map
and Where to Use Them


Let's look at the heat maps we can generate using eSpatial:

Hot spot heat map

1. Hot Spot Heat Maps: Visualizing Clusters.

Ignore boundaries. Focus purely on high and low activity patterns.

The use case: Customer density. Darker shades reveal where your people actually are, independent of territory lines.

Regional heat map

2. Regional Heat Maps: Comparing Performance.

Use boundaries (states, territories) to measure metrics.

The use case: Aggregate sales volume. Color scales show the total value per region.

Which Type of Heat Map?


Don't just map. Ask why. The decision you need to make dictates the map you generate.

1. Go Regional: Compare boundaries

  • Best for: Comparing performance across ZIP codes, states, or territories
  • The goal: See which defined areas are winning or losing

2. Go Hot Spot: Spot density

  • Best for: Understanding concentration at a local level
  • The goal: Ignore borders to find true clusters of activity

What Are Heat Maps Good For?


The right map isn't just a visual, it's a competitive edge. Use eSpatial heat maps to turn raw data into critical strategy for your sales team.

1. Spot Customer Clusters.

Get a high-altitude view of your marketplace. Perfect for sales and marketing teams. Map your potential customers (population) against your actual office locations.

Real-world example: A Kansas sales organization used this to visualize gaps between their physical offices and high-density customer targets.

2. Refine Distribution.

Build a service network that actually reaches your customers.

Use heat maps to visualize customer density against your current locations.

  • Maximize access: Locate centers where the demand is highest
  • Cut waste: Identify centers that are too far from the action and move them closer to the clusters

3. Target Campaigns.

Use heat maps to layer third-party demographic data over your territories.

Real-world example: A Texas fashion retailer used regional heat maps to identify high-value ZIP codes.

The result: They placed billboards exactly where their target demographic lived, rather than spraying and praying.

  • Maximize ROI: Spend your budget only in high-density target zones
  • Execute faster: Identify the best ZIP codes instantly

4. Pinpoint Expansion.

Use regional heat maps to find your next franchise location.

How it works: Map your existing stores (stars) against incoming customer inquiries (heat markers).

The signal: High heat + No stars = Opportunity.

  • Identify areas with high inquiry volume but low physical presence
  • These are your ideal spots for expansion

5. Investigate Sentiment.

Don't wait for churn numbers to tell you something is wrong. Map customer satisfaction rates nationwide to spot risks instantly.

The Visual Code

  • Green: High satisfaction. Strong territory
  • Red: Low satisfaction. Danger zone

The Impact

  • Act fast: Identify dissatisfied territories immediately
  • Stop churn: Intervene with management support before you lose business

6. Track Profitability.

Revenue is geography. You need to know where you make the most money. Use heat maps to isolate high-profit customer clusters instantly.

The Impact

  • Pinpoint winners: See exactly where your best customers live
  • Compare locations: Benchmark territories against each other to find your true profit centers

7. Optimize Coverage.

Match incoming customer inquiries to your current sales coverage.

Visualize your team's true addressable market to spot inefficiencies instantly.

  • Fill gaps: Identify high-demand areas with zero coverage
  • Cut overlap: Stop reps from competing for the same turf
  • Allocate smart: allocate resources with actual demand

8. Ignite Field Sales.

Starting cold is hard. Field reps often waste time deciding where to begin.

Use heat maps to identify high-opportunity "pockets" instantly. Give your reps a concrete starting line.

The Coaching Edge

  • Assess: Visualize team metrics on a regional map
  • Coach: Move from abstract numbers to concrete data. See the complete performance picture at a glance

9. Evaluate Performance.

Raw revenue tells a partial story. Don't judge reps solely on one number. Use regional heat maps to reveal the market reality behind the sales figures.

The Insight

  • See obstacles: Factor in competitor density and excessive drive time
  • Coach fairly: Identify true development needs by understanding the territory difficulty, not just the dollar signs

Generating a Regional Heat Map


It's easy to create a heat map for regional analysis in eSpatial. Start by setting up a free trial account and then follow these steps:

Step 1

Upload Your Point Data

You first have to add data to your map – it will form the basis for all of your analysis and be displayed as points on your map. This could be sales data, service data, demographic information and other KPIs, with one row for each unique address.

Click the Add Data option from the control panel. Then click Upload new data and follow the instructions.

Make Your Heat Map
understandable and Useful


Using sensible design practices when creating your dynamic heat map is critical to ensuring other users understand the story your data is telling. Consider the following key factors when the time comes for you to generate your map.

1. Choose colors that communicate your story best

The right colors can help your users better understand the data on a map. We recommend using darker hues to represent high-density and brighter colors in the same family (i.e., darker and lighter shades of blue) for low-density. Look at the population density map on the right as an example: It uses different gradients of red, orange, and yellow to display states with higher, more moderate, and lower densities, respectively.

2. Choose the correct data display settings

How you cluster your data will determine if your users understand your story. If you create a national-level map, then state-by-state data clusters are OK. But if you believe your users will want to drill down into an individual state or ZIP code, then having the data divided into sub-level clusters will give your users a more granular view of the data.

Layer Additional Data Onto Heat Maps


Use heatmaps as a base map for other data. The heat map generator in eSpatial can create either, but the process differs between the two (as outlined above).

Imagine you run a chain of long-term care facilities across the U.S. You could use eSpatial to create a map showing the retirees' levels per state in percentages. Then, you can add data from your business to the map, such as the number of care homes you operate in each state. It will allow you to spot opportunities for expansion in an instant.
