Table 3.4 - SCANNING MODE

Details:

• Section: 3
• Octet: 72
• Applicable Grid Templates: 0-3, 40-43, 204

Reserved Bits:

• None

Special Values:

• None

Description

This table defines the scanning mode flags used in GRIB2 files, specifying the scanning direction and row/column offsets.

Notes

• (1). i direction - West to east along a parallel or left to right along an x-axis.
• (2). j direction - South to north along a meridian, or bottom to top along a y-axis.
• (3). If bit number 4 is set, the first row scan is defined by previous flags.
• (4). La1 and Lo1 define the first row, which is an odd row.
• (5). Di and Dj are assumed to be positive, with the direction of i and j being given by bits 1 and 2.
• (6). Bits 5 through 8 may be used to generate staggered grids, such as Arakawa grids (see Attachment, Volume 1.2, Part A, Att. GRIB).
• (7). If any of bits 5, 6, 7 or 8 are set, Di and Dj are not optional.

This table defines individual bit flags. To use them, you will need to extract the relevant bit from the byte at Octet 72 (index 71) and convert it using the corresponding From<u8> implementation.

Trait Implementations

impl Clone for Grib2Table3_4

fn clone(&self) -> Grib2Table3_4

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Grib2Table3_4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Grib2Table3_4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<u8> for Grib2Table3_4

fn from(val: u8) -> Self

Converts to this type from the input type.

impl PartialEq for Grib2Table3_4

fn eq(&self, other: &Grib2Table3_4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
