OpenRepGrid vs sits: at a glance
What is OpenRepGrid?
Repertory grids learn which pole is the preferred one — a data-model change, not another plot option.
OpenRepGrid is the R toolkit for repertory grid analysis, the personal-construct-psychology technique of rating elements against bipolar constructs. Releases arrive every few months and the package passed JOSS review in late 2024. The current release, 0.1.18, is the largest in the window: a rebuilt import/export layer and the introduction of construct pole preference into the grid object itself.
What is sits?
An R package for satellite time series just grew a Python API.
sits classifies satellite image time series — building data cubes from cloud archives, training deep learning models on them, and producing land-cover maps. The releases here are dense feature lists in a steady 1.5.x line, and two themes recur in every one: more source collections wired in, and more of the classification pipeline made parallel or chunked. Version 1.5.3 added pysits, a Python API onto the same engine.

OpenRepGrid

Repertory grids learn which pole is the preferred one — a data-model change, not another plot option.
◆ Current state
OpenRepGrid is the R toolkit for repertory grid analysis, the personal-construct-psychology technique of rating elements against bipolar constructs. Releases arrive every few months and the package passed JOSS review in late 2024. The current release, 0.1.18, is the largest in the window: a rebuilt import/export layer and the introduction of construct pole preference into the grid object itself.
◆ Where it's heading
The arc moves from presentation outward to the data model. 0.1.15 and 0.1.17 were about plots, colours, clustering options, and base-R ergonomics — subsetting by element name, cbind, names(). 0.1.18 changes what a grid can hold rather than how it is drawn, and threads that new attribute through import, construction, and analysis in one release. Getting data in and out is clearly the other priority: three dataframe layouts, long and wide Excel, multi-sheet import, workbook export.
◆ Prediction
With preferred poles now representable, the next likely step is analysis built on top of them — ideal-element distance and alignment measures — plus continued expansion of the import formats the package accepts.
sits
0.0INFRA · APIS
An R package for satellite time series just grew a Python API.
◆ Current state
sits classifies satellite image time series — building data cubes from cloud archives, training deep learning models on them, and producing land-cover maps. The releases here are dense feature lists in a steady 1.5.x line, and two themes recur in every one: more source collections wired in, and more of the classification pipeline made parallel or chunked. Version 1.5.3 added pysits, a Python API onto the same engine.
◆ Where it's heading
The package is positioning itself as the interface layer to Earth observation archives rather than as an algorithm library. Each release absorbs another provider — Planetary Computer, Digital Earth Africa and Australia, CDSE, TERRASCOPE, Open Geo Hub, PLANET — so the differentiator is coverage and the uniform cube abstraction over it. The Python API extends the same logic to the language most of that community actually works in. Alongside, the work is increasingly about scale: chunk parallelisation, multicores sampling, GPU classification, WebGL rendering.
◆ Prediction
With collections still being added release over release, expect more providers and continued performance work on the classification and regularisation paths. The open question the entries do not answer is how far pysits tracks the R API, since it appears once and is not mentioned again in later releases.

Frequently asked questions
What is the difference between OpenRepGrid and sits?
Both compete on the same themes — r-package — within Infra & APIs. OpenRepGrid and sits are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is OpenRepGrid better than sits?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. OpenRepGrid and sits are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
