Another reason to migrate to the ArcGIS Online New Map Viewer: Popups
The new ArcGIS Online map viewer, which debuted in early 2021, contains many enhancements that instructors, researchers, students, and others are finding incredibly useful. One advantage the new viewer has over what is now known as the "classic viewer" is improved popup imagery functionality.
Consider the popup size in one of my vegetation surveys as mapped in ArcGIS Online classic viewer, below. While you can click on the image and pull it up as a larger size in a separate browser tab, the image in the map popup is rather small.
In the new map viewer, you can make the popup larger. To do this, change the "show as list" from the list list mode to gallery mode as shown below. The gallery mode makes the images much larger. Plus, you can dock or undock the popups in the new map viewer for additional flexibility.
Equally wonderful is that apps that are based on the new map viewer also take advantage of this and other new capabilities. These include story maps, dashboards, and more. See my example below that shows the side-by-side comparison of a dashboard I built for a storm drains education project with the new viewer (left side) vs the classic viewer (right side).
This may seem like a small enhancement, but was a desire voiced by many educators over the years. The message is: Keep those suggestions coming! Our education team is in continued close communication with our product developers and other tools and we relay these suggestions directly to them.
