Keep the interfaces that work.
Migrate one workflow at a time.

Honua exposes documented GeoServices REST, OGC, OData, tile, gRPC, MCP, and SDK surfaces. Existing clients can keep using familiar interfaces where their required operations are supported. Check each protocol, operation, client version, and evidence boundary before planning a cutover.

Check the operation, not just the protocol name.

Published support claims link to a public test suite, parity matrix, or evidence document. The summaries below separate partial GeoServices REST parity, a dated OGC CITE snapshot, and SDK package maturity. Use the claims matrix for the underlying evidence.

Use compatible URLs where the operations your workflow needs are covered.

Honua targets selected FeatureServer, MapServer, ImageServer, Geometry Service, GeocodeServer, NAServer, and GPServer operations. Coverage differs by service and operation. The public parity matrix and JSON file in honua-server identify implemented, pending, and deferred behavior.

The 2026-05-17 snapshot reports 952/952 passing applicable, basic, or core assertions across 11 CITE suites. This is Honua's own test evidence, not formal OGC certification. The link below records the suite profiles, run scope, and audit trail.

Familiar workflow shapes, with availability stated per language.

The JavaScript SDK and migration companions are public prereleases. Python and .NET remain source previews, and Honua does not yet publish an automated .NET or MAUI source rewriter. Review the migration page and package evidence before choosing a path.

Connect the data sources your workflow actually needs.

Use PostGIS as the operational store, import supported exchange formats, or serve supported cloud-native formats from object storage. Confirm provider and operation coverage for your workload before deployment.

01 · Relational PostGIS first, with additional relational connectors.

Honua uses stock PostGIS as its read/write operational store, without a proprietary geometry type. MySQL/MariaDB, SQL Server, Oracle Spatial, and DuckDB are additional read/query-only providers. Validate schema features, authentication, and supported query operations for each provider.

PostGIS 3.x · PostgreSQL 14+primary store
MySQL/MariaDB · SQL Server · Oracle · DuckDBread/query only
PostgreSQL/PostGIS on RDS · Azure Database for PostgreSQL · self-hosteddeployment paths
02 · File & geodatabase Import the formats your team already exchanges.

Operator-facing import paths cover common file and geodatabase formats. Import is one-way today, and preservation details vary by format; review the documented parity before moving production data.

GeoJSON · KML · GML · WKT · CSVimport
FlatGeobuf · TinyWKBimport
03 · Cloud-native object storage Range-fetched paths for supported read-heavy workloads.

Honua can serve supported COG, PMTiles, STAC, and Zarr paths from object storage; COG and PMTiles use range requests. NetCDF4, HDF5, and GRIB sources are registered by URL and optionally converted by a GDAL worker to derived Zarr; when that build-time reader is disabled, refresh and pixel-read paths return 501 rather than serving incomplete data.
