Vr Symbols to/from VrPoints (SymPoi)

Symbols-Points01     Symbols-Points02

VrPoints (left) converted to Vr Symbols (right)

 

Type: Batch Application

 

Converts Symbols to or from VrPoints.

Detailed Description

VrPoints are typically used to define point cloud items such as LiDAR points and DSM (Digital Surface Model) points. For more information about VrPoints, see VrPoints Data Structure. The Symbols to/from VrPoints batch application converts between the two data types.

 

While there are some common attributes between the two data types such as x,y,z, and layer, much of the attribute data is lost in the conversion. Also, Vr Symbols were not intended as mass storage for point cloud data and contain larger attribute data than do VrPoints. Conversions of large amounts of VrPoints to Vr Symbols can cause very large file sizes and slower software run times.

 

NOTE: It is strongly recommended that the VrOne files to be converted are backed up before running this batch application.

Parameters for Vr Symbols to/from VrPoints

Symbols-Points03

Workspaces to consider

Defines the workspaces to consider when running this batch application.

Layers to search

Defines the layers that are to be searched for Vr Symbols or VrPoints and converted. A number line may be used to define the layers. Layers that are turned off will not be considered even if they are specified.

Conversion mode

Defines the conversion direction from Vr Symbols to VrPoints or VrPoints to Vr Symbols.

Convert symbols to points - Vr Symbols will be searched for and converted to VrPoints.
Convert points to symbols - VrPoints will be searched and converted to Vr Symbols.

Replace mode

When converting between data types, this option defines if the original Vr Symbols or VrPoints will be deleted.

Replace existing entities - The original Vr Symbols or VrPoints, will be deleted.
Add as new entities - The original Vr Symbols or VrPoints will not be deleted and new entities will be added to the VrOne database resulting in a Vr Symbol and a VrPoint at the same location.

Set Symbol parameters

Allows the entry/edit of the Vr Symbol parameters when the "Conversion mode" is set to "Convert points to symbols".

 

Symbols-Points04

Vr Symbol parameters

Set VrPoint parameters

Allows the entry/edit of the VrPoint parameters when the "Conversion mode" is set to "Convert symbols to points". VrPoints contain up to 16 parameters (attributes) for each point and the conversion to VrPoins allows the definition of only six of these parameters.

 

Symbols-Points05

VrPoint parameters (attributes)

Load parameters

Allows the current translation parameters to be recorded to a user defined file.

Record parameters

Loads the translation parameters from a previously recorded parameter file.

Reset parameters

Resets the translation parameters to default values.
