Changelog

Source: NEWS.md

edr4r 0.3.0

  • Supersede the GitHub-only v0.2.0-rc.1 and v0.3.0-rc.1 previews with the final 0.3.0 release.
  • Preserve the id and properties of a top-level GeoJSON Feature when geometry conversion is unavailable, instead of returning an empty fallback tibble. An id property continues to take precedence over the top-level id, matching sf/GDAL conversion behavior.
  • Add structured service and collection capability discovery, support checks, endpoint diagnostics, and per-client TTL caching for discovery metadata.
  • Add collection-instance discovery and optional instance-scoped paths across all query verbs and edr_explore().
  • Add a documented compatibility contract plus frozen Met Office Labs metadata/terrain fixtures for deterministic cross-server tests.
  • Preserve nonstandard CoverageJSON coordinates as appended .axis_* columns instead of silently discarding their identity. Batch deduplication now keeps distinct members, plots group/facet them, and coverage maps expose selectors and dimension-aware popups. A versioned edr_covjson_metadata attribute retains effective domain, axis, and referencing metadata across package binding and checkpoint/resume paths.
  • Harden spatial visualization around CRS semantics. Coverage maps reject declared projected or other known non-WGS 84 CRSs and coordinates or inferred cell bounds outside Leaflet longitude/latitude ranges; missing/custom CoverageJSON references warn before a range-checked fallback. Station sf geometries are transformed to WGS 84 for display without changing source-CRS matching-distance behavior, and missing station CRS metadata warns before plausible coordinates are used as-is. Projected source coordinates remain valid in edr_plot() grids.
  • Advance the location-batch checkpoint schema to version 2 so checkpoints written before custom-axis identity and CoverageJSON metadata preservation cannot be mixed with newly parsed rows.
  • Add explicit include_parameters = TRUE support to edr_location_batch(). A full collection- or instance-scoped parameter catalog is attached once as result$parameters, without duplicating definitions on observation rows or silently adding discovery calls to the default batch path. Resumed checkpoints validate before metadata access and can attach fresh cached metadata without repeating completed data requests.
  • Expand parameter discovery with instance-scoped edr_parameters(), explicit unit-definition and symbol-type fields, official EDR 1.1 data-type metadata, and preserved custom collection dimensions.
  • Add EDR 1.1-compatible WKT MULTIPOINT, MULTIPOLYGON, and MULTILINESTRING query inputs, including Z/M/ZM dimensional markers. Named custom-dimension query parameters continue through ..., and explicit advertised f tokens can override the pygeoapi-compatible f=json default.
  • Add opt-in, bounded GeoJSON pagination to edr_locations() and edr_items(). The client follows server-advertised rel = "next" links, supports cursor- and offset-based servers, and refuses unsafe cross-origin continuations or silent partial results at configured caps.
  • Add edr_location_batch() for safe, finite, sequential multi-station pulls with stable request/data/error tables, explicit station provenance, and stop-or-collect failure handling.
  • Add bounded calendar time-window planning to edr_location_batch() with station-by-window request caps, month-end/leap-year handling, normalized window provenance, and optional exact boundary-row deduplication. Requests remain sequential so the existing retry and throttling policy stays in control.
  • Add opt-in checkpoint/resume support for edr_location_batch(). Parsed successful and empty responses are installed atomically per request, so an interrupted bounded pull can reuse terminal windows while retrying only unresolved work. Checkpoints are locked, plan-fingerprinted, and reject incompatible or corrupt state before network activity.
  • Reuse the batch execution engine inside per-location edr_explore() while preserving its existing output and summary-warning contract.
  • Accept finite, safely representable numeric strings in CoverageJSON ranges that declare a numeric dataType, as currently emitted by USGS waterdata, while rejecting text, overflow/underflow, and unsafe declared integers.
  • Add edr_add_stations() for composing one or more independently styled station groups over an existing coverage map, reusing interactive chart and CSV popups. Coverage layers now render in a lower Leaflet pane, grid legends identify the active parameter/unit, and grid colour scales support identity, square-root, and log1p transforms.
  • Upgrade the cross-endpoint Lake Mead vignette to a precomputed interactive map that switches between Met Office population and Copernicus elevation grids beneath toggleable USGS and USBR/WWDH station groups with time-series popups. A companion plot facets discharge, gage height, and reservoir storage by parameter and unit. The full widget is deployed only on the pkgdown site; package builds retain a small faceted static fallback.
  • Remove a precomputed base64 map from the USGS vignette, reducing that source file by about 1 MB while retaining the runnable interactive-map example.

edr4r 0.1.1

CRAN release: 2026-07-10

  • Harden CoverageJSON parsing: honor NdArray$dataType, preserve textual identifiers and invalid/mixed timestamps, validate array shape and axes, support tuple/composite trajectory axes, merge child parameter metadata, and fail clearly for tiled or externally referenced data.
  • Return typed empty results for HTTP 204 responses, report single Coverage and Feature documents correctly, and reject JSON error bodies when CSV was requested.
  • Retry transient transport failures by default, with a client option to disable them, and exercise retries against a real local HTTP server.
  • Make corridor_height required, validate radius/corridor distances and units, and reject non-finite or reversed bounding boxes consistently.
  • Make edr_explore(method = "auto") choose bulk spatial queries only when the matching spatial input is supplied. Capability discovery failures now stop before an accidental per-station request fan-out.
  • Add a max_requests safety cap to per-location exploration, preserve station identity in combined plots, and avoid optional location discovery calls for grid/profile and data-only bulk results.
  • Add grid and vertical-profile plot views to edr_plot(), with automatic view detection.
  • Allow edr_explore() to return plots or data for gridded/profile coverage queries, including method = "position" for profile-style responses.
  • Add interactive coverage maps to edr_map() and edr_explore(), with in-map selectors for gridded coverage slices (parameter, datetime, z) and profile selectors for parameter / datetime.
  • Materialize CoverageJSON regular-grid axes declared with start, stop, and num.
  • Warn when per-station edr_explore() fallback fetches fail.
  • Tighten collection-id, coordinate, and WKT validation.
  • Add max_match_distance to edr_map() for bounded spatial matching.
  • Fix map filtering and matching so blank JavaScript values remain missing, requested parameters determine station availability, and all coverage groups assigned to the same station are retained.
  • Run R CMD check and coverage workflows on the dev branch as well as the release branch.
  • Add a real headless-Chrome smoke test for coverage-map controls, redraws, popups, and uncaught JavaScript errors.
  • Document the non-operational Met Office Labs EDR demonstrator and probe one tiny terrain query in a weekly/manual, non-blocking interoperability job.
