For these last six descriptors, the * unit is equal to the ratio of the basic angle and the subdivisions number. For ordinary cases, * zero and missing values should be coded, equivalent to respective values of 1 and 106 (10-6 * degrees unit). * - For data on a quasi-regular grid, in which all the rows or columns do not necessarily have the * same number of grid points either Ni (octets 31-34) of Nj (octets 35-38) and the corresponding Di * (octets 64-67) or Dj (octets 68-71) shall be coded with all bits set to 1 (missing). The actual * number of points along each parallel or meridian shall be coded in the octets immediately following * the grid definition template (octets [xx+1]-nn), as described in the description of the grid * definition section. * - A quasi-regular grid is only defined for appropriate grid scanning modes. Either rows or columns, * but not both simultaneously, may have variable numbers of points or variable spacing. The first * point in each row (column) shall be positioned at the meridian (parallel) indicted by octets 47-54. * The grid points shall be evenly spaced in latitude (longitude). * A scale value of radius of spherical Earth, or major axis of oblate spheroid Earth is delivered * from applying appropriate scale factor to the value expressed in meters. * - It is recommended to use unsigned direction increments. * - In most cases, multiplying Ni (octets 31-34) by Nj (octets 35-38) yields the total number of * points in the grid. However, this may not be true if bit 8 of the scanning mode flags (octet 72) * is set to 1. * @param section - byte block for template 3.0 * @returns - The parsed template */ export declare function grib2Template30(section: Reader): { /** Shape of Earth [Table 3.2](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_table3-2.shtml) */ shape: { code: number; value: string; }; /** Scale Factor of radius of spherical Earth */ radiusScaleFactor: number; /** Scale value of radius of spherical Earth */ radiusScaleValue: number; /** Scale factor of major axis of oblate spheroid Earth */ majorAxisScaleFactor: number; /** Scale value of major axis of oblate spheroid Earth */ majorAxisScaleValue: number; /** Scale factor of minor axis of oblate spheroid Earth */ minorAxisScaleFactor: number; /** Scale value of minor axis of oblate spheroid Earth */ minorAxisScaleValue: number; /** Number of points along a parallel (W-E) */ nx: number; /** Number of points along a meridian (N-S) */ ny: number; /** Basic angle of the initial production domain */ basicAngle: number; /** Subdivisions of basic angle used to define extreme longitudes and latitudes, and direction increments */ subdivisions: number; /** Latitude of first grid point */ lat1: number; /** Longitude of first grid point */ lon1: number; /** Resolution and component flags [Table 3.3](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_table3-3.shtml) */ resolution: { code: number; value: { iDirectionIncrements: { code: number; value: string; }; jDirectionIncrements: { code: number; value: string; }; vectorComponentResolution: { code: number; value: string; }; }; }; /** Latitude of last grid point */ lat2: number; /** Longitude of last grid point */ lon2: number; /** i direction increment */ dx: number; /** j direction increment */ dy: number; /** Scanning mode [Table 3.4](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_table3-4.shtml) */ scanMode: { code: number; value: { xDir: { code: number; value: string; }; yDir: { code: number; value: string; }; adjacentDir: { code: number; value: string; }; rowDir: { code: number; value: string; }; rowOffset: { code: number; value: string; }; pointOffsetX: { code: number; value: string; }; pointOffsetY: { code: number; value: string; }; rowGridRule: { code: number; value: string; }; }; }; /** Grid Units */ gridUnits: string; /** * Convert this section into grid data * @param transformer - projection transformer * @returns - grid data */ buildGrid: (transformer?: Transformer) => VectorPoint<Record<string, number>>[]; }; //# sourceMappingURL=templates.d.ts.map
