◆ RasterSamplingMode

enum class luciad::RasterSamplingMode
strong

Sampling mode of a raster.

luciad/rasters/RasterSamplingMode.h

The following image clarifies the interpretation of the sampling mode. The green rectangle represents the bounds of the image. On the left side the colored rectangles represent pixels in an area-sampled basic image and on the right side the colored dots represent pixels in a point-sampled basic image.

Enumerator
Area 

Area-sampled data.

Each sample applies to the area covered by a pixel. This is for example the case for data that is retrieved using a photometric sensor. This is often used for color data.

Point 

Point-sampled data.

Each sample applies to a single point. This is for example the case for data that is retrieved using laser scanning. This is often used for elevation data.
