Load Types

Dataset

interface Dataset {
  title: string;
  unitFormat: UnitFormat;
  attribution: string;
  datetimeRange: OpenDatetimeISOStringRange;
  datetimes: DatetimeISOString[]; // deprecated, use `loadDatasetSlice` instead
  palette: Palette;
}

Dataset metadata.

DatasetSlice

interface DatasetSlice {
  datetimes: DatetimeISOString[];
}

Dataset slice with available datetimes in the requested datetime range.

DatasetData

interface DatasetData {
  datetime: DatetimeISOString;
  referenceDatetime: DatetimeISOString;
  horizon: DurationISOString;
  image: TextureData;
  datetime2: DatetimeISOString | null;
  referenceDatetime2: DatetimeISOString | null;
  horizon2: DurationISOString | null;
  image2: TextureData | null;
  imageWeight: number;
  imageType: ImageType;
  imageUnscale: [number, number] | null;
  bounds: [number, number, number, number];
}

Dataset data.

• datetime - closest start forecast datetime <= requested datetime

• referenceDatetime - reference datetime of datetime, i.e. datetime of model run

• horizon - duration between referenceDatetime and datetime, e.g. PT6H for a 6-hour forecast

• image - image at datetime

• datetime2* - closest end forecast datetime >= requested datetime

• referenceDatetime2* - reference datetime of datetime2, i.e. datetime of model run

• horizon2* - duration between referenceDatetime2 and datetime2, e.g. PT6H for a 6-hour forecast

• image2* - image at datetime2

• imageWeight* - interpolation weight between image and image2

• imageType - image type, scalar or vector

• imageUnscale - original data value bounds, used to unscale the data if the original data are scaled (quantized)

• bounds - original data bounding box

* applicable only if datetimeInterpolate is enabled

TextureData

interface TextureData {
  data: Uint8Array | Uint8ClampedArray | Float32Array;
  width: number;
  height: number;
}

Texture data to be used as input to raster rendering layers.

UnitSystem

enum UnitSystem {
  METRIC = 'METRIC',
  METRIC_KILOMETERS = 'METRIC_KILOMETERS',
  IMPERIAL = 'IMPERIAL',
  NAUTICAL = 'NAUTICAL',
}

Unit system for unit format definition.

UnitFormat

interface UnitFormat {
  unit: string;
  scale?: number;
  offset?: number;
  decimals?: number;
}

Format definition to be used for formatting raw values with units.

Datetime Types

DatetimeISOString

type DatetimeISOString = string;

Valid ISO 8601 datetime.

DatetimeISOStringRange

type DatetimeISOStringRange = [start: DatetimeISOString, end: DatetimeISOString];

Valid ISO 8601 datetime range.

OpenDatetimeISOStringRange

type OpenDatetimeISOStringRange = [start: DatetimeISOString | null, end: DatetimeISOString | null];

Valid ISO 8601 datetime range. Null start/end represent an open end.

DurationISOString

type DurationISOString = string;

Valid ISO 8601 duration.
