gps2gtfs vs rasterpic
A side-by-side editorial comparison of gps2gtfs and rasterpic — release velocity, themes, recent moves, and the top alternatives to consider.
gps2gtfs vs rasterpic: at a glance
What is gps2gtfs?
gps2gtfs spent a release making its docs stop describing functions it does not have.
gps2gtfs converts raw GPS traces into GTFS transit feeds, with a Rust backend behind the R interface. The only entry on record is 0.3.2, an explicitly documentation-only release: the trip extraction functions stop claiming to read CSV files when their own parameter docs always said data.frame or path, the bundled stop and terminal datasets state their Kandy, Sri Lanka provenance, and titles are normalized to sentence case.
What is rasterpic?
rasterpic became an S3 generic and picked up stars support; the rest is upkeep
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.

◆ Current state
gps2gtfs converts raw GPS traces into GTFS transit feeds, with a Rust backend behind the R interface. The only entry on record is 0.3.2, an explicitly documentation-only release: the trip extraction functions stop claiming to read CSV files when their own parameter docs always said data.frame or path, the bundled stop and terminal datasets state their Kandy, Sri Lanka provenance, and titles are normalized to sentence case.
◆ Where it's heading
One entry is not a trend, but the release is unusually precise about its own boundaries, stating outright that no behavior, signature, or return value changed and citing 533 passing tests from a clean detached clone with the specific CI job numbers. That level of provenance in a documentation patch suggests a maintainer treating the package as something others audit.
◆ Prediction
There is not enough history here to predict a direction. The Rust backend is the notable structural detail, and whether it expands is the question the next release will answer.

◆ Current state
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.
◆ Where it's heading
The direction is broader input-class coverage inside the same single-function design, and tighter integration with the plotting ecosystem downstream. 0.3.0 renamed output layers to r/g/b/alpha specifically to stay compatible with tmap 4.0; 0.5.1 restored the RGB specification on masked and inverted output after it regressed, and moved errors and warnings to cli formatting. Releases are frequent but small.
◆ Prediction
With the generic in place, adding further input classes is now cheap, so that is the likely direction. The 0.5.1 regression on mask/inverse output suggests the RGB-specification path is the fragile part worth watching.
