Overview
This article outlines the steps required to integrate Nearmap imagery into OpenGov Cartegraph software. The integration leverages the ArcGIS Online Custom Basemap Gallery, allowing users to access their imagery and features within the OpenGov platform using their ArcGIS Online credentials. OpenGov supports most of the standard aerial imagery formats supported by ArcGIS Online.
NOTE: This integration is also possible in ArcGIS Portal, but ensure that your Portal is correctly configured and accessible by OpenGov.
Prerequisites
Before you begin the integration process, ensure that you have the following:
- An ArcGIS Online or ArcGIS Portal account with administrative privileges.
- An OpenGov software account.
- Aerial imagery files ready for upload. This could either be static images in GeoTIFF/JPEG format or a web mapping service from an API.
- WMS 2.0 for geofenced area
- Tile API for nation-wide basemap of latest captures using WGS84 which is excellent for web environments
- Access to ArcGIS Online Custom Basemap Gallery.
Setting Up ArcGIS Online custom basemap gallery
Creating a Custom Basemap Gallery Group
- Log into your ArcGIS Online account.
- Navigate to Groups and select Create Group.
- Fill in the required details (Name, Summary, Tags, etc.).
- Set the Access to the appropriate level (Public, Organization, etc.) - Note, users should not use Publicly Available data and should restrict usage to their organization.
- Click Save.
Adding Basemaps to the Gallery
- Navigate to the Content section.
- Add a specific Tag or multiple tags to view your basemap gallery.
- Select the basemaps and imagery layers you want to include in your custom basemap gallery.
- Click on Share and select the custom basemap gallery group created earlier.
- Ensure the basemaps are accessible to the desired user groups.
Hosting Nearmap Imagery in ArcGIS Online
- Navigate to the Content section.
- Click Add Item and select From my computer or From the web depending on the source of your imagery.
- Upload your aerial imagery files or provide the URL to the hosted imagery.
- Fill in the necessary details (Title, Tags, Summary, etc.).
- Click Add Item to upload the imagery.
- Share the uploaded imagery with the custom basemap gallery group created in the previous step.
Connecting ArcGIS Online to OpenGov
- Open OpenGov Software and navigate to the Settings or Integration section.
- Look for the option to integrate with ArcGIS Online or Portal.
- Click Connect and enter your ArcGIS Online credentials.
- Grant OpenGov Software access to your ArcGIS Online account when prompted.
- Confirm the connection is successful.
Accessing Imagery in OpenGov
- Log into OpenGov Software using your ArcGIS Online credentials.
- Navigate to the Requests, Work, or Assets tab showing the basemap section within OpenGov.
- Browse and select the desired web map containing imagery or features from the gallery.
- The selected imagery will now be available within OpenGov for your projects.
Troubleshooting
Imagery Not Showing in OpenGov
Ensure the imagery is correctly shared with the Custom Basemap Gallery group and that OpenGov has access to the correct ArcGIS Online account.
Connection Errors
Verify that your ArcGIS Online credentials are correct and that you have administrative privileges.
