TemporalTileProvider

Inherits TileProvider

Members

Name	Documentation	Type	Description	Optional
Mode	The mode that his temporal tile provider operates in. In the Prototyped mode, a given start and end time, temporal resolution, and perscriptive time format is used to generate the information used by GDAL to access the data. In the folder method, a folder and a time format is provided and each file in the folder is scanned using the time format instead	String	In list { Prototyped, Folder }	No
Colormap	If provided, the tile provider will use this color map to convert a greyscale image to color	String	Value of type ‘String’	Yes
FixedTime	If the ‘UseFixedTime’ is enabled, this time will be used instead of the actual time taken from OpenSpace for the displayed tiles	String	Value of type ‘String’	Yes
Folder		Table	Table parameters	Yes
Interpolation	Determines whether this tile provider should interpolate between two adjacent layers	Boolean	Value of type ‘Boolean’	Yes
Prototyped		Table	Table parameters	Yes
UseFixedTime	If this value is enabled, the time-varying timevarying dataset will always use the time that is specified in the ‘FixedTime’ property, rather than using the actual time from OpenSpace	Boolean	Value of type ‘Boolean’	Yes

Table parameters for Folder

• Optional: Yes

Name	Documentation	Type	Description	Optional
Folder	The folder that is parsed for files. Every file in the provided directory is checked against the provided format and added if it adheres to said format	Directory	Value of type ‘Directory’	No
Format	The format of files that is pared in the provided folder. The format string has to be compatible to the C++ function get_time. https://en.cppreference.com/w/cpp/io/manip/get_time	String	Value of type ‘String’	No

Table parameters for Prototyped

• Optional: Yes

Name	Documentation	Type	Description	Optional
Prototype	The text that will be used as the prototype to generate the data to load the image layer. Any occurance of ${OpenSpaceTimeId} in this prototype is replaced with the current date according to the remaining information such as the resolution and the format and the resulting text is used to load the corresponding images	String	Value of type ‘String’	No
TemporalResolution	The temporal resolution between each image	String	Value of type ‘String’	No
Time	The starting and ending times for the range of values	Table	Table parameters	No
TimeFormat	The specification of the date format that is used in the tile provider. The time format must be specified in a manner appropriate for the SPICE function timout_c. https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/cspice/timout_c.html	String	Value of type ‘String’	No

Table parameters for Time

The starting and ending times for the range of values

• Optional: No

Name	Documentation	Type	Description	Optional
End	The (inclusive) ending time of the temporal image range	String	Value of type ‘String’	No
Start	The (inclusive) starting time of the temporal image range	String	Value of type ‘String’	No
