What is osmextract?

osmextract stopped throwing your OpenStreetMap downloads away at the end of every session.

osmextract downloads OpenStreetMap extracts from Geofabrik, BBBike and openstreetmap.fr and translates them into sf objects via GDAL. The 0.6.0 release moved its download cache from `tempdir()` to a persistent `tools::R_user_dir()` location and raised the R floor to 4.1.0 to get it. It also made spatial `place` inputs self-clipping: pass an sf or bbox object and the boundary is now set to match, so only the relevant slice of a country-sized extract is processed.

What is parzer?

A coordinate parser whose entire job is surviving how badly humans write latitude and longitude.

parzer converts messy coordinate strings — degrees, minutes, seconds, assorted symbols, arbitrary whitespace — into decimal degrees. Development is slow and sporadic, with three-year gaps between releases, and the work splits between C++ performance in the internal scrub() path and a long tail of parsing bugs. The most recent release, 0.4.4, fixed two genuinely dangerous ones: a leading space could silently drop a negative sign, and an E in a longitude string returned NA while a W parsed fine.

osmextract stopped throwing your OpenStreetMap downloads away at the end of every session.

◆ Current state

osmextract downloads OpenStreetMap extracts from Geofabrik, BBBike and openstreetmap.fr and translates them into sf objects via GDAL. The 0.6.0 release moved its download cache from `tempdir()` to a persistent `tools::R_user_dir()` location and raised the R floor to 4.1.0 to get it. It also made spatial `place` inputs self-clipping: pass an sf or bbox object and the boundary is now set to match, so only the relevant slice of a country-sized extract is processed.

◆ Where it's heading

Two threads run through every release. One is chasing GDAL — SQL syntax adjusted for 3.10, ogr2ogr options fixed for 3.9, and an `osmconf.ini` that 0.6.0 finally keeps automatically in sync with whatever sf or GDAL provides rather than shipping a snapshot. The other is the road-network extraction added experimentally in 0.3.1, which has been quietly accumulating real routing semantics since: `access = no` links retained when the mode-specific tag permits them, a `oneway` column by default for driving, and `motor_vehicle` always included.

◆ Prediction

Given that `oe_get_network()` has gained transport-mode detail in three separate releases while remaining flagged as experimental, the next substantive work is most likely there — either more modes or a formal exit from experimental status.

0.0

A coordinate parser whose entire job is surviving how badly humans write latitude and longitude.

◆ Current state

parzer converts messy coordinate strings — degrees, minutes, seconds, assorted symbols, arbitrary whitespace — into decimal degrees. Development is slow and sporadic, with three-year gaps between releases, and the work splits between C++ performance in the internal scrub() path and a long tail of parsing bugs. The most recent release, 0.4.4, fixed two genuinely dangerous ones: a leading space could silently drop a negative sign, and an E in a longitude string returned NA while a W parsed fine.

◆ Where it's heading

The package has settled its scope — 0.4.1 explicitly rewrote the documentation to say it parses coordinates rather than validates them — and now moves only when someone finds a string it mishandles. Recent work has also been about shedding weight: Rcpp dependence reduced, the C++ requirement dropped from DESCRIPTION, suggested dependencies removed, and the vignette builder moved to Quarto. Maintainership passed to a new maintainer in 2022 and the package has stayed within rOpenSci.

◆ Prediction

The next release will most likely be another batch of parsing edge cases reported by users, since that is what every release since 0.2.0 has been. Nothing in these entries points to new functionality.
