accessibility vs jmastats: at a glance
What is accessibility?
An urban accessibility toolkit that grew into a distributional-equity toolkit.
accessibility, from IPEA's geo team, computes how reachable opportunities are given a travel matrix and land use data. Since the 1.0.0 rebuild it has widened well past reachability metrics: 1.1.0 added inequality and poverty estimation alongside spatial availability and balancing cost, 1.2.0 added the concentration index and Theil T, and 1.3.0 let spatial_availability() return results per origin-destination pair with the underlying balancing factors exposed.
What is jmastats?
A Japan Meteorological Agency client whose real product is keeping its bundled datasets current.
jmastats pulls weather and climate data from the Japan Meteorological Agency into R, and most of its releases exist to refresh the station and reference datasets it ships. Three of the four versions on record are dataset updates, dated by the month they were cut. The exception is 0.3.0, which taught jma_collect() to retrieve climatological normals derived from past observations.

◆ Current state
accessibility, from IPEA's geo team, computes how reachable opportunities are given a travel matrix and land use data. Since the 1.0.0 rebuild it has widened well past reachability metrics: 1.1.0 added inequality and poverty estimation alongside spatial availability and balancing cost, 1.2.0 added the concentration index and Theil T, and 1.3.0 let spatial_availability() return results per origin-destination pair with the underlying balancing factors exposed.
◆ Where it's heading
The package is moving from measuring access to measuring who is left out, and doing it by adding metrics rather than reworking the core. A second, quieter theme is generality — nearly every parameter that once took a single value now accepts vectors or lists, so users can sweep across cutoffs and decay specifications in one call. The decay family keeps growing, most recently with a logistic form.
◆ Prediction
Further inequality or decay functions are the most likely next addition, given that both families have grown steadily and neither shows signs of being considered complete; the entries give no indication of another breaking restructure.
jmastats
0.0ANALYTICS
A Japan Meteorological Agency client whose real product is keeping its bundled datasets current.
◆ Current state
jmastats pulls weather and climate data from the Japan Meteorological Agency into R, and most of its releases exist to refresh the station and reference datasets it ships. Three of the four versions on record are dataset updates, dated by the month they were cut. The exception is 0.3.0, which taught jma_collect() to retrieve climatological normals derived from past observations.
◆ Where it's heading
The package treats bundled data as the thing that must not go stale, and the retrieval API as broadly finished. Where code does change, it is about being a well-behaved client — request intervals to reduce server load, messages when returned data contains missing values, corrected station coordinates. Capability growth happens in single steps, roughly once a year.
◆ Prediction
The next release is most likely another dated dataset refresh; a further extension of jma_collect() to a new observation type is plausible but the entries show no specific one being prepared.
