LizardTech, a provider of software solutions for managing and distributing geospatial data, will launch Version 10 of its GeoExpress data manipulation and compression software at the 2018 GEOINT Symposium. GeoExpress 10 includes significantly expanded LiDAR data handling capabilities and improved interface communication.
GeoExpress is LizardTech’s flagship software product originally created to enable geospatial professionals to manipulate digital satellite, aerial, and UAV images and losslessly compress them to industry-standard MrSID or JPEG2000 files for more efficient use. The addition of LiDAR handling in 2015 and 2016 releases gave GeoExpress the ability to natively compress LiDAR data to MrSID and LAZ formats with no loss of data content, saving up to 75% on storage and processing time, as well as support for high-density BPF point clouds.
“Users can do a lot more with their LiDAR data in GeoExpress 10,” said Toby Martin, LizardTech Vice President, Development and Strategy.
In past versions of the software, GeoExpress performed only basic compression and mosaicking of LiDAR point clouds. The new version enables users to reproject LiDAR files into different coordinate systems and crop the data to create smaller files. Individual files or single tiles within a mosaic may be cropped to a desired area of interest for easier and faster processing. Additionally, GeoExpress 10 allows the user to crop by elevation, adding a third dimension to spatial image management.
“You can use the elevation cropping function to create point clouds of just the mountain peaks in an area, for example, if you are planning a high-elevation project,” said Martin.
In GeoExpress 10, users will also find the overall experience of interacting with their data sets is more intuitive thanks to enhanced information and communication from the software. Users may now select the data sets they want to mosaic together, and the software presents a selection of processing options which may be applied to those files.
Another general upgrade in the new version is the ability to pause and then re-start a processing task without losing any progress already achieved. In the past, a task could only be stopped and started again from the beginning once it had been initiated, which for extremely large processing jobs may take significant resources to complete.
Other enhancements to GeoExpress 10 include:
- Compatibility with LZW compressed tiff files commonly output from Pix4D software.
- Addition of Esri projections to the Reprojection Manager.
- Addition of rectangular cropping around a center point.
- Shape cropping using Google Earth KML files.
In addition to GeoExpress 10, LizardTech will showcase its complete line of geospatial products at GEOINT 2018: Express Server® software for high-performance delivery and publication; the recently updated GeoViewer software, which is the fastest way to view MrSID and JPEG 2000 imagery; and the recently released Portfolio 2017 digital asset management solution, which makes it easy to organize, access, and share geospatial imagery alongside associated graphic and digital files.
