`geodetic_engine.projdb`¶

Build a custom PROJ database from a Georepository instance.

The public surface is deliberately small: a configuration object, a build function, a validation function, and the errors they raise.

Functions¶

`build`	Build an enriched proj.db from a Georepository instance.
`load_config`	Build a `ProjDbBuildConfig` from file, environment and overrides.
`validate`	Check that a built database is sound and that PROJ can read every object.

`AuthorityPreference`	How custom authorities enter PROJ's operation selection.
`BuildReport`	Provenance for one build, so a result can be traced after the fact.
`ProjDbBuildConfig`	Resolved configuration for one custom proj.db build.

`BallparkOnlyOperationError`	A non-deprecated object only resolves through a ballpark transformation.
`ConfigurationError`	The build configuration is missing or inconsistent.
`ForeignAuthorityCollision`	A row would overwrite an object belonging to another authority.
`MissingGridError`	A grid-based transformation references a grid file that is not available.
`MissingReferencedObjectError`	A custom object references an object that is not in the database.
`ProjDbBuildError`	Base class for all custom proj.db build failures.
`SchemaDriftError`	The base proj.db does not have the columns this builder expects.
`UnsupportedMethodError`	A coordinate operation method is not evaluable by this PROJ build.

Not exported from the subpackage, but returned or accepted by something that is.

A fresh build would drop authorities an existing output database holds.
