Adding multiple thematic maps in a single Layout with MapInfo 19

Telling Stories with Maps: Combining Thematic Visuals in MapInfo Pro 19

MapInfo Pro – it’s been a go-to tool for GIS pros for ages, right? It’s got this knack for turning boring data into eye-catching visuals, and one of its coolest tricks is thematic mapping. Now, MapInfo Pro 19 takes it up a notch. Imagine weaving multiple thematic maps together in a single layout. That’s what we’re talking about – a way to tell richer, more insightful stories with your data. Forget just showing information; we’re talking about creating compelling narratives. Let’s dive in and see how it’s done.

Thematic Mapping: More Than Just Pretty Colors

Okay, so before we get fancy with layouts, let’s quickly recap thematic mapping in MapInfo Pro. Basically, it’s where you style your map – colors, symbols, the whole shebang – based on the data you’ve got hooked up to it. Think of it as giving your map a personality based on the numbers.

You’ve got a few different types to play with, each with its own strengths:

• Ranges: This is your classic “color-coded map.” You pick a number range (like population density), and MapInfo Pro slaps on different colors for each range. Super intuitive.
• Individual Values: Got categories instead of numbers? No sweat. This lets you assign a unique style to each category, like different land use types.
• Graduated Symbol: Think of this as “bubble maps.” The bigger the bubble, the bigger the number. Great for showing absolute values, like total sales per region.
• Dot Density: This one’s cool. Each dot represents a certain quantity, and the more dots crammed into an area, the higher the value. It gives you a real sense of concentration.
• Bar and Pie Charts: Now we’re getting fancy! You can actually stick little charts right onto your map, showing multiple variables for each location. Perfect for comparing things side-by-side.
• Grid: Need to fill in the gaps? This uses interpolation to create a smooth, thematic surface.

Creating these maps is pretty straightforward. MapInfo Pro 19 has a wizard – find it under “Add Theme” on the Map tab – that walks you through the whole process. Pick your map type, table, and data field, then tweak the colors and styles to your heart’s content. One thing I really dig is the interactive theme tab. You can mess with the data and watch the map change in real-time. Plus, range themes now act like separate layers in a group, so you can toggle them on and off like a light switch. Handy!

Putting It All Together: The Multi-Thematic Layout

This is where the magic happens. Imagine being able to show multiple views of your data, all in one place. That’s the power of a multi-thematic layout. It lets you compare variables, highlight different aspects of the same data, and tell a much richer story. Here’s how you build one:

Pro Tips for Killer Layouts

• Color is Key: Don’t just slap on any old colors. Think about what you’re trying to communicate. ColorBrewer 2.0 is your friend here. It’s got palettes that are designed to work well together and be easy on the eyes.
• Legends That Make Sense: Make sure your legends are clear, concise, and accurately reflect what’s on the map. No one wants to guess what those colors mean.
• Balance is Everything: A good layout is like a good painting – it needs balance. Make sure no single element overpowers the others.
• Multiple Monitors = More Power: If you’ve got multiple monitors, use them! It makes it so much easier to juggle multiple map windows and the layout at the same time. I can’t go back to using just one screen!
• Customize Your Workspace: Don’t be afraid to tweak the ribbon interface to fit your workflow. Add your favorite tools to the Quick Access toolbar for lightning-fast access.
• Backup, Backup, Backup: Seriously, set up automatic workspace backups. You don’t want to lose hours of work because of a crash. Trust me, I’ve been there.

Wrapping Up

Combining multiple thematic maps in a single layout? It’s not just about making pretty pictures. It’s about unlocking deeper insights, telling compelling stories, and making better decisions. MapInfo Pro 19 gives you the tools to do it, and with a little practice, you’ll be creating maps that wow. So go ahead, experiment, and see what you can create!
