WorldWind Kotlin/earth.worldwind.formats.las/LasCrs

LasCrs

sealed interface LasCrs

Coordinate reference system detected from a LAS file's GeoKeyDirectory VLR. Only the cases the earth.worldwind.layer.pointcloud.PointCloudLayer can georeference without an external projection library are modelled; anything else surfaces as Unknown so the caller can supply a projection hook.

Types

object Absent : LasCrs

No GeoKey VLR at all.

object Geographic : LasCrs

X = longitude°, Y = latitude°, Z = height (m).

data class Unknown(val epsg: Int?) : LasCrs

CRS present but not one we reproject natively; epsg is the projected-CS code if known.

data class Utm(val zone: Int, val hemisphere: Hemisphere) : LasCrs

X = easting (m), Y = northing (m), Z = height (m), on the given WGS84 UTM zone.
