How to upload local data files to ArcGIS Online

We do not recommend finding mapping data in ArcGIS Online. Once you have found data from reliable sources, use this tutorial to bring your data into a shareable browser map.

Tutorial data

Download cambridge-tenure.geoJSON here.

  1. Log in to your ArcGIS Online account.
  2. In the main menu, select Content.

  3. Select New item.

  4. Upload a file from Your device.

    You can upload .geoJSON files as is. Shapefiles must be compressed into a .zip file first.

  5. Choose to Add and create a hosted feature layer.

  6. Follow any prompts. Be sure to populate at least Title and Tags, as they are necessary to publish the map in any future web or story maps.

  7. Select Save to publish the service.

  8. This dataset can now be used in a web map. To open the dataset in a web map, select Open in Map Viewer (you may have to engage the drop down next to Open in Map Viewer Classic to find this option for the more modern map viewer, which this guide is written for).

Save the map

Now that the data has been added, you can begin configuring the map (see tutorial section Next steps). After you are finished configuring your map, make sure you save the map. If you do not save your map, any StoryMaps you make using this data layer will not be shareable.

  1. Click the Save and open button in the left-hand menu.

  2. Populate the Title and Tags. If you do not add tags, you can’t share this maps or any future maps made with this map.

Making sense of data in ArcGIS Online

  1. Navigate back to your Content pane by clicking the menu icon in the upper-left hand corner of the page, and selecting Content.

  2. Make note of the ways ArcGIS classifies the different resources we have created.

    We have added the GeoJSON, a Feature Layer, and a Web Map. If you want to edit any of these items in the future, navigate to the Content pane. If you were to create a StoryMap based on this map, a fourth resource would be added titled Web Mapping Application.
