Data

Look up reference tables and provider data. Each result identifies its source and, when available, its update time.

86 tools in this category.

• Time-zone directory

  Filter IANA time-zone identifiers exposed by the current runtime.

• Country codes

  Search a bundled ISO-code list and display region names with Intl.DisplayNames. No live demographic or political data.

  Choose MET forecast by coordinates or latest NOAA airport-station observation by ICAO code. Forecast requires owner MET_CONTACT. Station data are not conditions at your exact location. Not for flight planning.

• Public holidays: UK / France

  Official published UK bank holidays and 13 French regional calendars; available years returned from each source. No inferred dates.

• Currency codes

  Bundled ISO currency names and codes. Snapshot, not exchange rates.

• Language codes

  Bundled ISO 639 language identifiers with two-letter aliases. Source: pycountry ISO database snapshot.

• Periodic table

  Element symbols, atomic numbers and approximate atomic weights from the bundled RDKit table. For educational reference, not chemical handling instructions.

• GTFS timetable viewer

  Local search in stops, routes, trips or stop_times from your authorized GTFS ZIP. At most 500 matching rows; no live arrivals, service-date filtering or calendar-exception prediction.

• RDF Turtle inspector

  Parses Turtle into triples: expands prefixes, shows object types, languages and datatypes, and filters triples.

• Terrain analysis

  Computes slope and aspect by Horn's method, D8 flow direction and flow accumulation for a digital elevation model.

• STAC inspector

  Reads a STAC catalog: type, links, items with bounds and time, filters by bbox and time range, lists assets.

• Machine-learning run comparison

  Compares experiment runs from the metrics you paste: validates the JSON, matches metric sets (a missing metric is a warning, not an error), computes minimum, maximum, mean and spread per metric, ranks runs by the primary metric in the max or min direction, flags dominated runs (no metric better than another run and at least one worse) and lists which parameters differ between runs. It works locally, without an MLflow server.

• Dataset versioning by blocks

  Splits text files into fixed-size blocks, computes a SHA-256 digest per block and per whole file, reports block and unique-block counts, the bytes saved by deduplication and builds a .dvc-like manifest so only the dataset description goes into git. Everything is computed locally and no file is uploaded anywhere.

• Zarr array block viewer

  Parses Zarr v2 metadata (.zarray and optional .zattrs): shape, chunks, dtype, compressor, fill_value, order and zarr_format. It computes the number of dimensions, the block grid, the total block count, bytes per block and the uncompressed array size, and for a given coordinate the block number per dimension, the offset inside the block, the linear block number, the block key and the C-order offset. The blocks themselves are never read.
