Heixel

Analogue to a pixel (picture element), a heixel is one element of a height field encoding the elevation of a surface. There are two basic types of heixels depending on the necessary precision of the height field:

  • 16bit integer with scale and bias
  • 32bit float

Undefined elevation values are denoted by a specific no-data value (e.g. −9999) or by a IEEE float NaN (not-a-number) value.
