Indiana WaterData Portal · concept

Data sources & integration

The portal's value is connection: it brings authoritative water data from many agencies into one place, without replacing any of them. Here is what feeds it, and how.

Connected and planned sources

Integration approach

  • Read-only connectors to each source's public API or service — the portal never becomes the system of record.
  • A normalization layer maps every source to common site, reading, and geography models, so a new source is a configuration, not a rebuild.
  • Compatibility-first with the IGIO Esri Enterprise portal (ArcGIS Enterprise 11.5), consuming the State's map and feature services read-only so authoritative GIS layers stay authoritative.
  • The DNR Salesforce database is the authoritative source for well log and significant-withdrawal records; the portal reads it through a scheduled, read-only connector.
  • Scheduled refresh with provenance: every value carries its source and timestamp, on a cadence recommended per source.
  • Designed for self-service growth: administrators register a standard source (a REST endpoint, a file drop, or an ArcGIS service) and set its cadence without code.

Out of scope, by design

  • Replacing existing agency databases.
  • Deploying new monitoring infrastructure.
  • Statewide water allocation or regulatory systems.

By design, this is a public-facing data and dashboard layer, not a database or regulatory rewrite. The agencies' own systems stay the systems of record.
