## Convert .ldr to PCAP

This option allows you to convert a Velodyne .ldr file to a de facto standard network packet capture file format called a .pcap file. Many publicly available Velodyne HDL packet captures use this PCAP file format as a means of recording and playback.

## Convert .PCAP to .ldr

This option allows you to convert a .pcap file to a .ldr file. You can obtain .pcap files from Network Packet Analyzer Programs such as Wireshark which is available for most platforms, including Linux, MacOS and Windows.

In order to use this tool, a verification code is required. To acquire your verification code, send an email to <support@phoenixlidar.com> with the title “Velodyne PCap to ldr Verification Code Request” and a screenshot of the version information of SpatialExplorer (accessible from the toolbar by navigating to Help → About). The verification code is unique to the computer on which SpatialExplorer is installed. Each computer running SpatialExplorer requires a verification code.

## Convert Riegl RXP to SDCX (MTA Resolution)

Sometimes it might be necessary to convert the .rxp file into an .sdcx file to correct the LiDAR range data for MTA (multiple time around) zones written into the .rxp file. SpatialExplorer has a built-in tool that can convert the LiDAR data to a usable file for general point cloud production as a first step in post-acquisition.

![How to Access Convert Riegl RXP to SDCX in SpatialExplorer 5.0 and above](/files/-LqDpWiTRshb7r6abBkv)

Select the .rxp files that will be converted to .sdcx. This can be a single .rxp file or multiple .rxp files.

![Selecting rxp file for sdcx conversion in SpatialExplorer 5.0](/files/-LqOB3njodq_-sd_jt3U)

Once the .rxp files have been selected, the next dialog box will present the various options that can be used for MTA resolution. We recommend leaving the default values as is for processing.

Once the .rxp to .sdcx conversion has finished, the existing project must be closed and re-opened in SpatialExplorer in order to properly load the .sdcx files.

{% hint style="info" %}
It is recommended to save the project prior to closing to avoid any loss of changes/configuration.
