ArcGIS Online and ArcGIS Enterprise
ArcGIS can support strong Māori GIS governance, but the platform settings do not replace governance. ArcGIS Online removes substantial infrastructure work and provides mature web, field and sharing tools. ArcGIS Enterprise provides greater control over the hosting environment but carries a much larger administration and upgrade burden.
ArcGIS Online
ArcGIS Online is a managed SaaS platform. Hosted layers, web maps and applications can be shared privately, with groups, across an organisation or publicly.
Genuine strengths
- rapid web publishing
- mature field collection tools
- group and role permissions
- hosted feature-layer views
- mobile/offline workflows
- integrated StoryMaps and application ecosystem
- managed infrastructure
- multiple export formats
For a hapū or iwi without a server team, avoiding infrastructure administration can be a meaningful sustainability benefit.
Export settings need careful interpretation
Esri's current documentation contains an important warning. The Allow others to export to different formats setting controls export while users access a hosted feature layer through the ArcGIS Online website. Esri states that this setting does not affect the ability of users with access to the underlying service to export through other clients such as ArcGIS Pro or custom applications.
For sensitive data, do not treat the visible export toggle as an absolute anti-copy control.
Instead ask:
- should the user have service access at all?
- can a restricted view provide only the necessary features and fields?
- should the external party receive a separate derivative dataset?
- is the access time-limited?
- what agreement governs copied information?
Hosted views can help separate audiences
ArcGIS Online hosted feature-layer views allow different filters and settings against a source layer. They can be useful for separating internal, partner and public views.
But understand the source relationship and test the actual access path. A view is an access mechanism, not a substitute for a governance decision.
A definition query is not always data minimisation
Esri's publishing documentation states that when publishing from ArcGIS Pro, definition queries can be applied to the published hosted feature layer while all source data may still be uploaded to ArcGIS Online. If only a subset should be stored there, Esri advises exporting the intended subset to another feature class and publishing that.
This is an important Māori GIS rule:
Do not assume that what the map displays is all the platform stores.
For a sensitive publication, create and inspect the actual publication dataset.
Metadata and item visibility
ArcGIS items can expose title, description, owner, thumbnail, tags and extent. Review the item as well as the map. See Metadata can give you away.
ArcGIS Enterprise
ArcGIS Enterprise is self-hosted or organisation-hosted infrastructure. It can provide greater control over:
- network architecture
- identity integration
- server location
- databases
- patch windows
- logging
- private services
That control has a cost. Enterprise deployments need continuing administration across operating systems, ArcGIS components, certificates, databases, backups, monitoring, upgrades and disaster recovery.
For a small organisation, self-hosting can therefore reduce vendor hosting dependence while increasing dependence on technical specialists.
ArcGIS Online versus Enterprise
| Question | ArcGIS Online | ArcGIS Enterprise |
|---|---|---|
| Infrastructure management | mostly provider | organisation/service provider |
| Initial deployment | comparatively fast | substantial |
| Hosting control | less | more |
| Upgrade burden | provider | organisation |
| Remote collaboration | strong | depends on architecture |
| Local/disconnected options | limited by SaaS model | possible with appropriate design |
| Ongoing specialist administration | moderate | high |
| Exit planning | data/app/config export and rebuild | data plus full platform migration |
Neither is automatically more sovereign.
Account ownership
For either platform:
- subscriptions should belong to the Māori organisation
- administrator accounts should not belong solely to a consultant
- at least two organisational administrators should exist
- role design should be documented
- full exports should be tested
- important source data should have an independent preservation copy
Practitioner note
Esri platforms have played a major role in Māori GIS capability because they make sophisticated web, field and presentation workflows accessible. The practical sovereignty question is not whether Esri is good or bad. It is whether the organisation understands the architecture well enough to control accounts, sharing, source data, copies, cost and exit.
The same standard should be applied to any commercial GIS platform.
