Today we’re going to talk about dynamic and animated maps. Dynamic maps update their data in real-time. Can anyone think of examples where this might be important?
Maybe for tracking traffic?
Or monitoring air quality!
Great examples! Dynamic maps are crucial for real-time scenarios. Animated maps, on the other hand, show changes over time, such as urban development. Have any of you seen an animated map like this?
Yes! I saw one showing how cities grew from 1990 to 2020.
Exactly! Tools like Tableau and ArcGIS Dashboards help create these maps. Remember the acronym D.A.A. for Dynamic and Animated Maps, which can help you recall their importance.
D.A.A. helps us remember that both provide crucial insights into changes.
To wrap up this session, dynamic maps are essential for real-time updates, while animated maps effectively visualize changes over time. Make sure to explore tools like Tableau!

Now, let’s discuss multivariate mapping. Who can tell me what that means?
Does it mean using multiple data sets on one map?
Exactly! It allows for complex visualizations. For instance, if we show rainfall patterns through color gradients and crop yields with proportional symbols. Why do you think this could be useful?
It helps in decision-making, especially in agriculture!
And civil engineering projects too!
Right! This technique is crucial for multi-criteria decision analysis in projects. To remember, use the mnemonic 'M.A.P.' for Multivariate Analysis in Projects.
That’s a clever way to remember it!
In summary, multivariate mapping combines multiple datasets for richer insights and is extremely valuable in various fields.

Advanced Techniques in Thematic Cartography
This section details advanced techniques in thematic cartography, designed to enhance the visualization and analysis of spatial data.
Dynamic and Animated Maps
- Dynamic Maps provide real-time updates, facilitating monitoring of situations like traffic flows and air quality.
- Animated Maps illustrate temporal changes, for example, depicting urban sprawl over different decades. Tools like Tableau, TimeSlider in QGIS, and ArcGIS Dashboards support these techniques.
Multivariate Mapping
- This technique integrates two or more datasets into one map, exemplifying complex information visually. For instance, presenting rainfall patterns as a color gradient while utilizing proportional symbols for crop yield effectively demonstrates multi-criteria decision-making (MCDA) in civil engineering projects.
3D and Virtual Cartography
- Utilizing Digital Elevation Models (DEMs) and LiDAR data, 3D cartography offers enhanced terrain visualization, critical for infrastructure planning, flood simulation, and slope analysis. Software tools like ArcScene, QGIS 3D View, BlenderGIS, and Google Earth Pro are instrumental in this area.
Cartographic Automation
- Automation tools such as Python scripting with ArcPy and ModelBuilder facilitate batch map creation, applying symbology, and exporting maps efficiently, reducing manual workload.
These advanced techniques not only improve the effectiveness and efficiency of cartographic practices but also push the boundaries of how spatial data can be represented and integrated in thematic mapping.

• Dynamic Maps update data in real-time, commonly used in monitoring traffic, air quality, and disaster situations.
• Animated Maps depict changes over time (e.g., urban sprawl from 1990 to 2025).
• Tools: Tableau, TimeSlider in QGIS, ArcGIS Dashboards.
Detailed Explanation
Dynamic maps continuously refresh data to display the most current information. For instance, they can show live traffic conditions or air quality levels that update as conditions change. On the other hand, animated maps present data in a time sequence, illustrating how certain variables evolve over a specified period. An example is visualizing urban development from 1990 to 2025, showing how the city has expanded. Tools like Tableau help create these visuals quickly and effectively by integrating datasets that can illustrate changes dynamically.
Examples & Analogies
Imagine a weather app on your phone: it continuously updates the current temperature and air quality index in your area, just like a dynamic map shows real-time information. Now think about a time-lapse video that shows a city being built over the years; that’s what an animated map does, showing how a location transforms over time.
Multivariate Mapping

• Combines two or more datasets in a single map.
• Example: Showing rainfall patterns (color gradient) and crop yield (proportional symbols) together.
• Complex but powerful for multi-criteria decision analysis (MCDA) in civil projects.
Detailed Explanation
Multivariate mapping is a technique where more than one type of data is represented on the same map. For instance, a map might use color gradients to indicate rainfall levels in one area while using circles of varying sizes to represent the crop yield in those same regions. This layering of data can be complicated but provides a comprehensive view that aids in decision-making processes like resource allocation for agriculture or infrastructural development.
Examples & Analogies
Think of a dish that combines multiple flavors – for instance, a colorful fruit salad. Each fruit adds its own taste and color, creating a richer experience. Similarly, in multivariate mapping, combining different datasets allows for a deeper understanding of how various factors, like rainfall and crop yield, interact and influence each other in agricultural planning.

• Use of Digital Elevation Models (DEMs) and LiDAR data for terrain visualization.
• 3D maps are essential in:
– Infrastructure planning in hilly terrain
– Flood simulation models
– Slope analysis for road alignment
• Software: ArcScene, QGIS 3D View, BlenderGIS, Google Earth Pro.
Detailed Explanation
3D and virtual cartography involve using advanced technologies like Digital Elevation Models (DEMs) and LiDAR data to create three-dimensional visualizations of terrain. These 3D maps help planners visualize landscapes, which is crucial for designing infrastructure in challenging terrains, such as mountains and valleys. For instance, when planning a highway, a 3D view can show how the road should curve around hills, ensuring safer and more efficient designs. This type of mapping is also used in simulations for flood risk assessments and analyzing slopes for construction projects.
Examples & Analogies
Consider the difference between looking at a flat map of a mountain region and a 3D model of that same region. The flat map merely shows you 2D information, while the 3D model helps you see the steepness of hills and valleys, making it easier to understand where to build a road or where a flood might occur – much like how architects use 3D models of buildings to visualize how a structure will look and fit within its environment.

• Use of Python scripting (e.g., with ArcPy) and ModelBuilder for batch map creation.
• Automates:
– Map generation
– Symbology application
– Exporting and publishing.
Detailed Explanation
Cartographic automation involves using scripts and tools to streamline map-making processes, making them faster and more efficient. For example, Python scripting allows cartographers to write code that automatically generates maps based on pre-defined templates and datasets. This reduces the time it takes to create maps manually and ensures consistency across multiple maps. ModelBuilder is another tool that provides a visual way to automate complex workflows in GIS. By automating tasks like applying symbology or exporting maps, cartographers can focus on analyzing the data rather than getting bogged down in repetitive tasks.
Examples & Analogies
Imagine using a photocopier: you only have to set it up once, and it can churn out page after page of the same document without you having to do anything else. Similarly, with automation in cartography, once everything is set up, the computer can produce numerous maps quickly and accurately on command, making the process much like creating multiple copies of a well-prepared document.
