Overview

Welcome to Lesson 8! In this lesson, we discuss another key topic in cartography: map generalization. Generalization, or transforming a map’s features (traditionally from large-scale to small-scale) to fit a map’s given scale and purpose, has been increasingly salient given the proliferation of interactive multi-scale web maps. Such maps are among a new generation of ”fast maps”, which include interactive, animated, and viral maps and mapping products. These maps, as well as other products of technological advancements in mapping, including 3D maps and extended reality applications, present new challenges and opportunities for geographers across many fields of interest.

In Lab 8, we break from our focus on mapping in ArcGIS and Tableau to design an interactive multiscale basemap using Esri's Vector Tile Style Editor online map design platform. To highlight the creative designs possible with such tools, we design this map by taking inspiration from a favorite piece of media/art/computer game/etc. Lab 8 thus ties together our discussion of generalization and interactivity with previous discussions of maps for advertising, map symbology, and basemap design.

Learning Outcomes

By the end of this lesson, you should be able to:

• describe the differences between content, geometry, and symbology generalization operators and their roles in multi-scale map design;
• evaluate a map designer’s use of selection and generalization on a map and the logical and ethical implications of these decisions;
• articulate the merits and challenges associated with designing and using animated and/or interactive maps (vs. static maps);
• discuss applications of cartography within the domain of Extended Reality (XR) – such as Virtual Reality (VR) and Augmented Reality (AR), while recognizing their respective disadvantages;
• design a custom multi-scale Mapbox basemap in the style of a movie, TV show, or other favorite piece of media and/or art.
