InterpolatableProperty

This page describes the possible content of a CZML document or stream. Please read CZML Structure for an explanation of how a CZML document is put together.

#InterpolatableProperty

The base schema for a property whose value may be determined by interpolating over provided time-tagged samples.

Interpolatable: no

##Properties

epoch - string

The epoch to use for times specified as seconds since an epoch.

interpolationAlgorithm - string

The interpolation algorithm to use when interpolating. Valid values are "LINEAR", "LAGRANGE", and "HERMITE".

interpolationDegree - number

The degree of interpolation to use when interpolating.

forwardExtrapolationType - string

The type of extrapolation to perform when a value is requested at a time after any available samples. Valid values are "NONE", "HOLD", and "EXTRAPOLATE".

forwardExtrapolationDuration - number

The amount of time to extrapolate forward before the property becomes undefined. A value of 0 will extrapolate forever.

backwardExtrapolationType - string

The type of extrapolation to perform when a value is requested at a time before any available samples. Valid values are "NONE", "HOLD", and "EXTRAPOLATE".

backwardExtrapolationDuration - number

The amount of time to extrapolate backward before the property becomes undefined. A value of 0 will extrapolate forever.
