duckspatial vs gps2gtfs
A side-by-side editorial comparison of duckspatial and gps2gtfs — release velocity, themes, recent moves, and the top alternatives to consider.
duckspatial vs gps2gtfs: at a glance
What is duckspatial?
duckspatial rebuilt itself around a lazy DuckDB class, then spent four releases filling in the geometry surface
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
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.

◆ Current state
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
◆ Where it's heading
The direction is to keep work inside DuckDB and make R the orchestration layer rather than the compute layer. 1.1.0 added macros so duckspatial functions work inside dplyr verbs; 1.1.1 moved the default to DuckDB v1.5.0 native spatial storage so CRS metadata persists in GEOMETRY columns; 1.2.0 added vector-tile output via ddbs_write_mbtiles() and the full family of geometry deserializers. Feature velocity has been high and consistent since the rewrite.
◆ Prediction
The remaining gaps are in PostGIS parity — the deserializers and tile writers landed in 1.2.0, so raster support or spatial indexing are the plausible next targets. 1.2.1 being a single message-capture fix suggests the 1.2.x line is now stabilizing.

2.5ANALYTICS
gps2gtfs spent a release making its docs stop describing functions it does not have.
◆ 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.
