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.
Defines a position. The position can optionally vary over time.
Extends: InterpolatableProperty
Interpolatable: yes
referenceFrame - string
The reference frame in which cartesian positions are specified. Possible values are "FIXED" and "INERTIAL".
Default: FIXED
cartesian - Cartesian3Value
The position specified as a three-dimensional Cartesian value, [X, Y, Z]
, in meters relative to the referenceFrame
.
cartographicRadians - CartographicValue
The position specified in Cartographic WGS84 coordinates, [Longitude, Latitude, Height]
, where Longitude and Latitude are in radians and Height is in meters.
Examples:
{
"position": {
"cartographicRadians": [ -1.3439035240356338, 0.6457718232379019, 100000 ]
}
}
cartographicDegrees - CartographicValue
The position specified in Cartographic WGS84 coordinates, [Longitude, Latitude, Height]
, where Longitude and Latitude are in degrees and Height is in meters.
Examples:
{
"position": {
"cartographicDegrees": [ -77, 37, 100000 ]
}
}
cartesianVelocity - Cartesian3VelocityValue
The position and velocity specified as a three-dimensional Cartesian value and its derivative, [X, Y, Z, dX, dY, dZ]
, in meters relative to the referenceFrame
.
reference - ReferenceValue
The position specified as a reference to another property.
delete - boolean
Whether the client should delete existing samples or interval data for this property. Data will be deleted for the containing interval, or if there is no containing interval, then all data. If true, all other properties in this property will be ignored.
