Tools and Software > Web-Based Tools
Last Updated on July 14, 2022
Web-based tools allow users to build maps, run basic spatial analyses, georefrence images (and much more!) without needing to download and install software. All of these tools can be accessed through a web browser with a basic internet connection.
ArcGIS Online is a cloud-based, collaborative workspace for making interactive maps, sharing data that you create, and performing spatial analyses. Users can create maps, scenes, and web apps, analyze data, and share their creations with other members of UMass or the wider public. Users also have access to ArcGIS Living Atlas of the World (a wide ranging source of maps, apps, and data layers that users can bring into their own projects).
Follow these steps to sign into ArcGIS Online using your UMass credentials:
- Go to https://www.arcgis.com
- Click Sign in in the top right corner of the window.
- At the login page, click: Sign in with Your ArcGIS organization’s URL.
- Type umass-amherst into the text box.
- Click Continue.
- Enter your UMass credentials to login.
ArcGIS StoryMaps is an online story-telling app that allows users to craft visually enticing narratives with images, text, and custom-designed maps. StoryMaps are saved to a user’s ArcGIS Online account (under “Content”) and can be shared with other members of the UMass organization or with the wider public.
To get started, visit the ArcGIS StoryMaps website and then follow the login instructions for ArcGIS Online.
