We’re pretty pumped. Why? Well, we always are — that’s how we make such great software. But in particular, our white paper on the MrSID Generation 4 (MG4™) technology has been republished by the good folks at GeoPlace.com, so that word about the format’s new features — support for multispectral imagery, alpha band transparency, support for LiDAR point cloud data and improved mosaics — can reach an even wider audience of users.

If you haven’t seen it yet we encourage you to read it and learn about the capabilities of LizardTech’s latest version of the format that first made it possible for geospatial professionals to use high resolution imagery in their applications and that continues to evolve with advancements in geospatial imaging.

LizardTech^® announced the release of GeoExpress 8 earlier this week at GEOINT. We’re excited about this latest version of the industry’s go-to manipulation and compression software for raster imagery. Here’s our director of Product Management, Jon Skiffington, giving GISCafe’s Sanjay Gangal the lowdown directly from the show floor.

We’ve had a lot of requests in recent years for support for multispectral and hyperspectral imagery — imagery with more than just the three color bands R, G and B. GeoExpress^® software now supports imagery with up to 255 bands, which for NAIP data users might mean 4-band “RGB plus infrared” (RGBIR). Other users may have imagery with hundreds of narrow bands that they use in specialized analyses.

Support for alpha bands, also new in GeoExpress 8, means users can exercise greater control over transparency in their image data. In creating the alpha band, users can specify that all image data should be regarded as opaque, or they can have GeoExpress query the image metadata to find out what color values to use for transparency areas, or they can specify color values.

We also improved our support for composite mosaics, which in the past were really quick at the viewing end but took a long time to create. Now the speed advantage serves both ends; composite mosaics encode quickly and open quickly in viewers.

These features are all enabled by the fact that we’ve updated LizardTech’s MrSID^® image format. MrSID Generation 4 (MG4™) is the next stage in the evolution of the image format geospatial users have turned into an industry standard. Support for MG4 in your favorite geospatial application by third parties is underway, and meantime, images compressed to MG4 can be viewed by either of LizardTech’s free viewers, the ExpressView™ Browser Plug-in utility or the standalone GeoViewer application (both available for download at http://www.lizardtech.com/downloads/viewers.php).

We hope that if you’re a GeoExpress user, version 8 will be the answer to some imaging needs you may have been just starting to recognize.  And if you haven’t tried GeoExpress…well, there’s never been a better time.

Let us know what you think of it!

We’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.
