pub enum Classification {
    CreatedNeverClassified,
    Unclassified,
    Ground,

    MediumVegetation,

    LowPoint,

The ASPRS classification table.

Classifications can be created from u8s and converted back into them:

use las::point::Classification;
let classification = Classification::new(2).unwrap();
assert_eq!(Classification::Ground, classification);
assert_eq!(2, u8::from(classification));

We make one modification to this table: we remove OverlapPoints, code 12. Las 1.4 added the extended point formats, which include an overlap bit. The overlap bit is intended to allow a point to both be an overlap point and contain some other classification.

Here's how we deal with that change:

• If the point format doesn't support the overlap bit, the classification is overwritten with the code for overlap points (12). On ingest, points with an overlap classification are given the Unclassified code and Point::is_overlap is set to true.
• If the point format does support the overlap bit, that is preferred.

Because of this change, trying to create a classification with code 12 is an error:

use las::point::Classification;
assert!(Classification::new(12).is_err());

Implementations

impl Classification

pub fn new(n: u8) -> Result<Classification>

Creates a new classification.

Throws an error if the classification is 12 (overlap).

Examples

use las::point::Classification;
assert_eq!(Classification::Ground, Classification::new(2).unwrap());
assert!(Classification::new(12).is_err());
