====== Optimize Data ======

This page describes the desktop tool “Optimize”. 

{{orbit_desktop:how_to_find.png?25&nolink  |}} Tools > Optimize \\ 
Drag & drop of a resource file that requires to be optimized for display will open this sidebar automatically.

===== Concepts =====

The Convert and Optimize Tools enable import, export, and data optimization of Reference Resources. 

"Optimize Data" optimizes one or more  [[dev:technology:supported_formats:index|supported resource files]] into a single Orbit-optimized resource file. \\
"[[dev:desktop:tools:convert_data|Convert Data]]" converts any supported resources file into another supported resource file, one on one. 

One sidebar to optimize supported Reference Resources of various types: Image, Vector, Point Cloud, and Mesh.

Optimizing original spherical images of mobile mapping resources to processed OMI images needs to be done using the "Optimize Imagery" procedure, see [[dev:desktop_ext:mapping:manage:imagery|Optimize Imagery]] ((Spherical mapping images are optimized and normalized, and this tool cannot be used)). 

===== Source =====

Set the source file or the source directory. 

  * When activating the option source file, it is possible to drag and drop the resource file inside the entry field.
  * When using a source directory, all supported resource files of the specified data type inside the selected source directory and, optionally, its including subfolders will be optimized. 
  * For point cloud data, a source crs is required. If available, the CRS value is derived from the resource header or the accompanied [[dev:technology:supported_formats:other:ord|Ord file]], else the [[dev:technology:core:crs|Map CRS]] will set as default.

===== Source Options =====

Available when using a source directory:

  * Select the file format of the source files to be optimized. \\ E.g.Filter a main directory of mapping runs to trajectory_simplified.ovt and all corresponding trajectory_simplified.ovt files will be optimized into a single target file. 

For point cloud LAS source files:
  * Optionally ignore the LAS bounds from the LAS header to import points out of bounds. 

===== Target =====

Set the target file and directory. 

  * The source directory and filename are preset as the default target file and directory. 
  * For point cloud data, a target CRS is required. The source CRS is preset as default.
  * Optionally when processing is completed, add optimized resource automatically to the [[dev:desktop:dataset:index|dataset list]]. 

===== Target Options =====

Available target options depend on the resource type 

==== Image data ====

Options for Image data, see [[dev:technology:supported_formats:image:omi]].
  * Pixel size
  * Image compression 
  * Threshold

==== Point Cloud ====

For options for Point Cloud data, see [[dev:technology:supported_formats:pointcloud:opc|]].
  * Ascii source files
  * Strip Attributes: Ignore attributes from the Source File when writing the Target file.
  * Filtering: Retain one point per voxel.
  * Classification: Ignore, import, or split the source point cloud by class.
  * RGB Color
  * Block Size

==== Mesh ====

Download the [[external:ccgeneratelod|Plugin]] to optimize formats into Web-Ready 3D Scalable Mesh (.w3sm).

==== Convert ====

Start process. \\
Upon cancellation, the ongoing process will be interrupted, if possible the preliminary processed target files will be created.
