I. Introduction

The Ubiquitous Map

How many of you have used a map on your phone in the last 24 hours?

Mapping apps are used BILLIONS of times a day.

We all carry maps in our pockets. But why? What makes them so essential?

II. Core Concepts

The Three Core Questions of a Mapping App

Where am I?

Location & Orientation

The little blue dot — instantly gives the user a sense of place and context.

Where is that place?

Search & Discovery

Find specific locations, businesses, or points of interest.

How do I get there?

Navigation & Movement

Routes and directions connecting your current location to your destination.

This simple design addresses the most common human needs related to space and movement.

III. Going Deeper

Google Maps is a one-size-fits-all tool.

For specialized questions, you need a specialized tool.

🎨

Customization

Can't see neighborhoods, voting districts, or pollution levels beyond standard views

📍

Adding Your Own Data

Can't map custom points of interest, like every tree on a university campus

🏷️

Adding Attributes

Can't store rich information about points — species, age, height, condition

IV. Specialized Tools — Esri Explorer

Introducing Specialized Mapping Apps

General Purpose (e.g. Google Maps)

Colorful, visually busy basemap
Limited customization
No custom data layers
Designed for everyday navigation

Specialized (e.g. Esri Explorer)

Intentionally minimal, neutral basemap so YOUR data stands out
Wider choice of basemaps
Supports custom data layers
Designed for fieldwork & data collection
Used in conjunction with web-based map creation tools

The background map is intentionally less colorful so your custom data stands out clearly on top.

V. The Real Power of Customization

Moving from Mobile to Web

Mobile Apps

(Google Maps, Esri Explorer)

Great for navigation, discovery & fieldwork

Web Browser

(Google Maps Web, ArcGIS Online)

Satellite imagery, traffic, transit routes

Custom Map Creation

Your own data. Your own maps. Your own purpose.

What if you want to use your own data, create your own maps, and customize them for a specific purpose? That's where we go beyond the standard free service.

* This isn't a criticism of Google Maps — it's an incredible tool — but it doesn't do everything.

Lesson Recap

Key Takeaways

Maps are essential tools — answering WHERE AM I, WHERE IS THAT, and HOW DO I GET THERE

General-purpose tools like Google Maps are powerful — but limited for specialized questions

Specialized apps like Esri Explorer — unlock custom data, attributes & fieldwork workflows

The real power of map creation lives in the web browser — beyond the standard free service

Geography isn't just about places. It's about asking the right questions.
