What are Thematic Maps? 

At Skywonder Technology Company Limited, we’ve been making GPS trackers and software to manage vehicles for over 12 years. We’ve learned how important data is for making smarter choices in moving goods, transportation, and many other areas. Today, I want to talk about something very important for understanding and using data: Thematic Maps.

What’s a Thematic Maps?

A thematic map is a special kind of map that focuses on one specific topic. Unlike regular maps that show different features like rivers and mountains, thematic maps are made to highlight certain information, like how many people live in a place, how much money people make, or even how often GPS trackers are used in different areas. These maps take raw data and turn it into something easy to see and understand, which is why they’re so useful in businesses like ours.

Types of Thematic Maps

Over the years, we’ve found that different kinds of thematic maps help us in different ways, each giving us useful information depending on what we’re looking at. Here’s a simple explanation of some of the most common thematic maps, along with their good and bad points:

1: Choropleth Maps

These maps use colors to show data in specific areas, like countries or states. For example, if we want to see where our GPS trackers are used the most in a country, a choropleth map would color those areas to show that.

Pros: Choropleth maps are easy to understand because they use colors to show information. They’re good for showing different kinds of data, like how many people live in a place or how much money they make. They work well for areas divided into regions, like countries or states.

Cons: Sometimes, these maps can make the data look simpler than it really is. Also, bigger areas might seem more important than they are, which can make the data look different from what it really is.

Examples: Large companies like Walmart use choropleth maps to plan their distribution strategies by visualizing population density and income levels across different regions, helping them decide where to place new stores or warehouses. 

2: Bivariate Choropleth Maps

These maps are like choropleth maps but show two different pieces of data at the same time. For example, we could look at both GPS tracker usage and traffic accident rates together.

Pros: These maps allow us to compare two things at the same time, which can give us more information. The colors can show how two sets of data relate to each other, making it easier to see patterns.

Cons: These maps can be hard to read, especially if you’re not used to looking at this kind of map. The colors can sometimes be confusing if they’re not chosen carefully.

Examples: FedEx uses these maps to analyze correlations between delivery times and traffic conditions, which helps them optimize routes and improve delivery efficiency.

3: Heat Maps

Heat maps use colors to show where things are happening the most, like where vehicles are moving or where there’s a high demand for our GPS services. They don’t need to stick to borders like cities or countries.

Pros: Heat maps are great for showing where the most activity is, such as areas with lots of traffic or high GPS tracker usage. They can show this without needing borders, which is useful for things that happen in bigger areas.

Cons: If the colors aren’t chosen right, the map can be hard to read. Without clear borders, it can also be tricky to tell exactly where the most activity is happening.

Examples: Companies like DHL use heat maps to track real-time package deliveries and vehicle movements. This helps them manage their fleets more effectively and ensure timely deliveries, especially during peak periods like holidays.

4: Dot Density Maps

These maps place a dot for every data point, which is great for showing where people live or where our GPS trackers are used. The more dots in an area, the more activity there is.

Pros: Dot density maps show data clearly by using dots to show where things are happening. They’re easy to understand and are good for showing patterns, like how people are spread out in an area.

Cons: In places with lots of dots, the map can get crowded, making it hard to see individual dots. Also, without clear lines showing where places start and end, it can be hard to know exactly where the dots are.

Example: During the 2020 U.S. Census, dot density maps were used to illustrate the distribution of race and ethnicity across different regions of the country. This helped to visualize how diverse or homogenous different parts of the U.S. are.

5: Value by Alpha Maps

These maps are similar to bivariate choropleth maps but are used when you want to compare two things that affect each other, like the size of a fleet and the area it covers.

Pros: These maps help us see how two things that affect each other are connected, giving us a better understanding of the data. They use different levels of transparency or color intensity to show this.

Cons: These maps can be hard to understand, especially if you’re not familiar with them. It can also be difficult to make an interactive version of these maps.

6: Graduated Symbol Maps

Instead of colors, these maps use symbols of different sizes to show data. For example, we might use larger circles on a map to show areas with more GPS trackers installed.

Pros: Graduated symbol maps are good for showing quantities, like how many GPS trackers are in different areas. The different symbol sizes make it easy to compare different places.

Cons: In areas with a lot of activity, the symbols can overlap and become confusing. Also, making these maps often requires extra work to get the data ready.

Applications of Thematic Maps in Our Industry

In our business, thematic maps have become super important. Whether it’s managing a fleet or planning the best routes, these maps give us the visual information we need to make smart decisions. For example:

• Logistics and Transportation: By using thematic maps, we can see traffic patterns, find problem areas, and plan better routes for delivery.
• Supply Chain Management: Thematic maps help us spot where things might get slowed down, so we can plan better and avoid delays.
• Retail and Services Sector: These maps help businesses understand where their services are needed the most or where they can find new opportunities.

Advantages of Using Thematic Maps

The best thing about thematic maps is that they turn complex data into something you can see and understand quickly. This is especially true in fleet management, where seeing patterns visually can help us make better decisions and work more efficiently. They also make it easier to share important information with others who might not be comfortable with raw data.

Conclusion

Thematic maps are more than just tools—they’re crucial for seeing data in a way that helps us make better decisions in our industry. Whether it’s planning routes, managing resources, or understanding market trends, these maps are an essential part of our work at Skywonder. They help us and our clients stay ahead in a very competitive market, making sure we provide the best services possible.

If you’re looking to get more out of your data, especially in fleet management, think about how thematic maps can give you the insights you need. They’ve made a big difference for us at Skywonder, and they can do the same for you.
