Online mapping

You have data - now what?

Picking up where yesterday left off, we now have access to a database full of trash-pickup efforts from all around the world. This data has a lot to tell us about the relationship between people, the oceans, and the ongoing pollution crisis. To unearth those answers, we must use the method geographers have been using for centuries to tackle just such inquiries - mapping!

For this task, we will be using ArcGIS Online, a versatile tool for online mapping and cartography:

"Build interactive web maps with ArcGIS Online, Esri's web-based mapping software. Gain new perspectives and enhanced details as you interact with data, zoom in, and search on the map... Understand your data in the context of location by using intuitive analysis tools. Reveal relationships, identify prime locations, use optimal routes, and analyze patterns to make predictions."

To get started, take your students through the lessons below. Start experimenting with the free, easy-to-use tools - and don't be afraid to get creative!



Analyze your students' Marine Debris Tracker data as a class. What were some common items they found? Did they notice any trends? Where were the heaviest concentrations of debris, and what might that tell us about human activity in that area?

Invite your students to discuss how mapping their data might help them reach answers to some of their questions, and why mapping of all kinds is important in the study of place.
