LiDAR Software: New Releases

Continuous developments in the hardware capabilities of LiDAR data acquisition have raised the demand for LiDAR data processing software that carries new tools for data manipulation and management. With the additional information becoming available through LiDAR surveys, solution providers are making efforts to develop more flexible processing structures to handle the growing volumes of data efficiently.

With developments in the data processing domain taking fast, we take a look at few news items (appeared in a period of last one year) pertaining to data processing tools.

Tiltan Systems Engineering of Israel, provider of 2D- and 3D -image generation systems and derived applications announced the release of its LiDAR data processing tool, TLiD. This tool is said to deliver faster and more accurate data processing of LiDAR point clouds, can generate geographic information layers and provide optimised 3D models for real-time applications. Its design provides extraction of DTM from bare earth to complex roofs and building shapes, trees and power lines.

QCoherent Software of USA, released LP360, a LiDAR software extension for ArcGIS, this year. The LP360 uses a specially-designed ArcMap™ data layer to access points directly from LAS files. It integrates LiDAR point cloud datasets into ArcGIS™ without requiring an import or conversion process. With LP360 LiDAR data can be combined with data in any format supported by ArcGIS.

Optech introduced DASHMap, the data processing software for its Airborne Laser Terrain Mapper (ALTM) product line. DASHMap boasts of having accelerated data acquisition-to-processing ratio, a simplified user interface with embedded 3D visualisation, tool for geodetic transformation and the elimination of intermediate processing files.

As per the sources, Optech also plans to collaborate with Canada based, InnovMetric Software Inc. to bundle ILRIS-3D products with the PolyWorks, a point cloud processing software suite. Under the terms of this agreement, Optech will bundle a license of the PolyWorks IMAlign module with each ILRIS system of Optech. Optech has also added a new feature to its scanner system, ILRIS-36D. Named as Profile Scanning, the new feature is designed to reduce ILRIS-36D scanning and post processing time by eliminating the need for alignment overlaps. The new software synchronises the rotational speed of the pan and tilt base with vertical scanning action to capture a complete or selected portion of a continuous 360 degree scene.

PCI Geomatics announced the signing of an original equipment manufacturer (OEM) agreement with Ambercore Software Inc. for the creation of Geomatica LiDAREngine, which was launched late last year 2006. Geomatica LiDAREngine is a data management, analysis, and visualisation tool for LiDAR data. It’s architecture and algorithms are for processing very large volumes of LiDAR data. The combination of Geomatica product line with LiDAREngine are said to offer faster ortho-image processing with improved accuracy.

In March this year, Cloud Peak Software, LLC, introduced LiDAR Surface Magic 2. It provides unsupervised classification of non-ground features like vegetation and buildings in LiDAR point clouds, resulting in a ground surface. The algorithm adapts to the terrain condition, freeing the user from the manual task of providing multiple parameterizations. With improved scaling for high density data, Surface Magic 2 effortlessly processes data from the newest LiDAR instruments.

Apart from the commercial software, mention should be made here of the Martin Isenburg’s homepage (https://www.cs.unc.edu/~isenburg/) that provide online tools for fast visualisation of LiDAR data in Google Earth. Martin is from University of North Carolina, and has posted tools that allow quick conversion of LiDAR data into contour and DEM Google Earth KMZ files. The process involves taking the original LiDAR data, simplifying it down to generate contours, then converting it directly to either transparent contour overlays, or high-resolution DEM reflectance overlays. The site, among other, also provides tools for converting, viewing and compressing LiDAR data.

However, nothing much was seen in the open source area in the past one year. GRASS 6.2.2 was released this year, but with no new features added (apart from bug fixes in the 6.2.1 source code), the new release does talk of having improved LiDAR data processing capability.

Apart from processing the point cloud data to produce elevation models, high-resolution LiDAR data opens new possibilities for Automated Feature Extraction (AFE) tasks. The two major solutions of AFE available from Visual Learning Systems (VLS) of USA are Feature Analyst and LiDAR Analyst 4.2. Feature Analyst exists as extensions to ERDAS IMAGINE, SOCET SET, the ArcGIS suite, and GeoMedia. Lately extension capabilities to Remote View have also been provided. LiDAR Analyst 4.2 is the new VLS product that automates 3D capture of buildings, trees, and bare earth terrain from LiDAR data. In 2006 VLS introduced the concept of Feature Modeler and the Feature Model Library (FML) as tools within Feature Analyst to automate the feature extraction workflow process. Feature Modeler provides users with a comprehensive set of tools for examining and refining feature models created with Feature Analyst. FML resides within a relational database and is used for storing AFE models to support enterprise-wide geospatial processing. Analysts can search and retrieve AFE models for subsequent processing in a batch mode to extract features from imagery without any training sets. The Feature Modeler software allows a user to import an AFE model to examine and adjust parameter settings or deploy a learning model in a batch-processing mode.

Robust and reliable tools for data processing have always been in demand in the user community keeping in view the amount of data that LiDAR acquisition generates. Last few years have seen the shift in data processing wherein manipulation and classification of data is now done using post-processing software that are third-party stand-alone products and now widely available in the market. Companies are also targeting to remove shortcomings in user interfaces of the currently available LiDAR processing systems and LiDAR add-packages with regards to intuitivness and efficiency that may make the production process less tedious. The future scenario of the data-processing domain may best be put as in the words of Arlan Pool, Technical Director, Mercury Computer Systems who says “You will want to do more of the processing closer to the sensor. Instead of sending a host of raw data down for further processing, it will be possible to process that data on board the aircraft and to deploy the LiDAR exploitation tools on the spot.”
