MrSID Generation 4 gains support
November 20th, 2009 by Jon SkiffingtonWe’re pretty excited. Last week we announced that version 11.01 of Global Mapper supports LizardTech™ MrSID™ Generation 4 (MG4) among its many supported elevation formats. Mapmakers who use Global Mapper will now benefit from being able to load point clouds compressed using LizardTech Lidar Compressor™ into Global Mapper.
Earlier this week we were able to announce that Merrick & Company has similarly integrated MG4 support into its MARS® (Merrick Advanced Remote Sensing) software application. Users of MARS 6.0, available now, can load MG4 files into MARS for visualizing and managing LiDAR terrain datasets.
How are they doing this? They’re using LizardTech’s MrSID Generation 4 Decode SDK, a free download.
Oh, and we should remind any ArcGIS 3D Analyst users that MG4 files are supported via LizardTech’s free MrSID Plug-in for ArcGIS 3D Analyst (http://www.lizardtech.com/download/dl_options.php?page=plugins), so you can work with MG4 files the same way you work with LAS files to create contours and surfaces.
The way we feel about all this is: The more the merrier.

Will the files typically have almost the same loading time in your application and in 3rd party applications or are there any limitations on the free SDK? Thanks for the swift reply and keep up the good work!
STH,
I was sure I had already sent a response to your question — I remember writing it. I apologize for leaving you hanging so long. We don’t inhibit the free decode SDK in any way, so you and any other third-party developer should be able to get the same performance as in our application.
Thanks for asking.
