	Sample many points; result.size() == pts.size().

	Mean absolute pixel size in raster-CRS units (0 when closed). Callers resampling along a path use this to pick a step that follows the DEM without oversampling it.

Here is the caller graph for this function:

crsWkt()

QString mesh::DTMSampler::crsWkt

(

)

const

Native CRS WKT of the raster (empty if the file had none).

Here is the caller graph for this function:

errorMsg()

QString mesh::DTMSampler::errorMsg ( ) const

inline

Last error message produced by open or sample.

isOpen()

bool mesh::DTMSampler::isOpen ( ) const

noexcept

open()

bool mesh::DTMSampler::open	(	const QString &	path,
		int	band = 1
	)

Open a raster by path. Returns false on failure (set errorMsg).

Parameters

path	GDAL-readable path (GeoTIFF, ASC, NetCDF, etc.).
band	1-based band index (most DTMs are single-band; default 1).

delete

pixelSize()

double mesh::DTMSampler::pixelSize

(

)

const

Mean absolute pixel size in raster-CRS units (0 when closed). Callers resampling along a path use this to pick a step that follows the DEM without oversampling it.

Here is the caller graph for this function:

sample()

double mesh::DTMSampler::sample	(	double	x,
		double	y
	)		const

Sample one coordinate (in raster CRS). Returns NaN on out-of-bounds or NoData.

Here is the caller graph for this function:

sampleBulk()

QVector< double > mesh::DTMSampler::sampleBulk

(

const QVector< QPointF > &

pts

)

const

Sample many points; result.size() == pts.size().
