You can't download portals for ArcGIS. Portals are online platforms, not downloadable files.
Here's how you can interact with ArcGIS portals:
- Access the ArcGIS Online Portal: This is the most common way to use portals. You can access it through a web browser at https://www.arcgis.com/.
- Create your own ArcGIS Enterprise Portal: This option allows you to host your own portal on your servers. You can download and install the software from the ArcGIS website.
Understanding ArcGIS Portals:
- ArcGIS Online: A cloud-based platform offering various mapping and geospatial analysis tools.
- ArcGIS Enterprise: A platform that allows you to set up your own portal on your servers, providing more control and customization.
Remember, you can't directly download portals. They are hosted services accessible through web browsers.
