LizardTech has launched version 10 of its GeoExpress data manipulation and compression software, GeoExpress 10. It 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 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 percent on storage and processing time, as well as support for high-density BPF point clouds, the company says.
Previous versions of 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. Additionally, GeoExpress 10 allows the user to crop by elevation, adding a third dimension to spatial image management.
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.
