What is CatastRoNav?

Navarre's cadastre client finally reaches feature parity with its bigger Spanish sibling.

CatastRoNav wraps the Cadastre of Navarre, a Spanish region that publishes its own cadastral services separately from the national system. Until 1.0.0 the package could only fetch cadastral parcels via ATOM; it now retrieves buildings and addresses through ATOM as well and adds WMS INSPIRE layer access through catrnav_wms_get_layer(). The same release relicenses to GPL-2, moves requests to httr2 with retries and switches messaging to cli.

What is constants?

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

Navarre's cadastre client finally reaches feature parity with its bigger Spanish sibling.

◆ Current state

CatastRoNav wraps the Cadastre of Navarre, a Spanish region that publishes its own cadastral services separately from the national system. Until 1.0.0 the package could only fetch cadastral parcels via ATOM; it now retrieves buildings and addresses through ATOM as well and adds WMS INSPIRE layer access through catrnav_wms_get_layer(). The same release relicenses to GPL-2, moves requests to httr2 with retries and switches messaging to cli.

◆ Where it's heading

The package is being pulled into line with CatastRo, the maintainer's national-cadastre client: same transport, same UTF-8 normalization strategy, same option names falling back to the CatastRo equivalents. Coverage has been gated by what the Navarre Cadastre actually publishes — 0.1.0 said outright that further ATOM capabilities would arrive when the regional service made them available, and 1.0.0 is that promise landing.

◆ Prediction

Expect the next releases to track new Navarre service endpoints as they are published, and to inherit whatever maintenance pattern CatastRo adopts next.

The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.

◆ Current state

constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.

◆ Where it's heading

The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.

◆ Prediction

Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.
