This pages describes the desktop additional tool “Optimize”. This tool is automatically launched when you drag & drop a ** point cloud file** into Orbit Software. \\

===== Concepts =====

"Optimize Data" optimizes one or more  [[206:technology:supported_formats:index|supported resource files]] into a single Orbit optimized resource file. \\
"[[206:desktop:tools:convert_data|Convert Data]]" converts any supported resources file into another supported resource file, one on one. \\ 

Optimizing mobile mapping images to .omi files can be done using the desktop procedure [[206:desktop_ext:mapping:manage:imagery|Optimize Imagery]]. This procedure is different from the "Optimize data" and "Convert data" tool, in that sense that there is an additional normalization process part of it.

===== Sidebar =====

=== Data Type ===

One and the same sidebar is used to optimize Image, Vector and Point Cloud resources. \\ 
Choose the applicable data type. 

=== 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 [[206:technology:supported_formats:other:ord|Ord file]], else the [[206:technology:core:crs|Map CRS]] will set as default.

=== Target ===

Set the target file and directory. 

  * The source directory and filename are preset as 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 [[206:desktop:dataset:index|dataset list]]. 

=== Options ===

It is not possible to set the data type. The optimize tool generates the according Orbit optimized resource files [[206:technology:supported_formats:image:omi|*.omi]], [[206:technology:supported_formats:vector:ovt|*.ovt]] and [[206:technology:supported_formats:pointcloud:opc|*.opc]].

** Point Cloud ** 

Options for Point Cloud data, see [[206:technology:supported_formats:pointcloud:opc|]].
  * Ascii source files
  * Strip Attributes
  * Filter points
  * Density

** Image data **

<note warning>Converting\optimizing *.jpg files into *.omi requires a lot of memory. For bigger files (in sense of number of pixels, physical size on the disk and compression factor don't influence memory usage) please increase memory allocation for Orbit software (how to do it please see here [[206:desktop:workspace:configurations|]])</note>

Options for Image data, see [[206:technology:supported_formats:image:omi]].
  * Pixel size
  * Image compression 
  * Threshold

=== Convert ===

Start process. \\
Upon cancel the ongoing processed will be interrupted and if possible the preliminary target file will be created.
