ENVI LiDAR™ is an interactive geospatial software environment that allows you to create powerful, realistic 3D visualisations and easily extract important features and products from LiDAR data. This important information can now conveniently be included in your geospatial analysis projects like, viewshed studies, forest inventories, right-of-way analyses, and urban planning. With ENVI LiDAR, you can quickly prepare your data, accurately extract features, fine-tune your results, and export your products for further analysis.
In the past, understanding the exact height and dimension of manmade and natural objects often required field analysis costing organisations time and resources. The ENVI LiDAR workflow allows you to transform your point cloud data and extract essential information for your geospatial applications without leaving the office. Beginning with data preparation, ENVI LiDAR allows you to quickly and easily identify and extract 3D features, refine your results, and export 3D products that can be fused with traditional 2D imagery for further analysis or inclusion in your GIS.
The Intuitive ENVI LiDAR Analysis Workflow:
Professionals across industries use LiDAR data to enhance their understanding of the geospatial information they use to make critical decisions. Whether applying LiDAR data to civil planning, natural resource management, geological exploration, or defence and security, ENVI LiDAR allows users utilise LiDAR data to create realistic 3D visualisations, extract 3D features, and export products and layers.
The ENVI LiDAR workflow allows you to transform your point cloud data and extract essential information for your geospatial applications. Discover the intuitive steps of ENVI LiDAR analysis workflow.
Transform 3D data with ENVI LiDAR
ENVI LiDAR uses multi-threading technology that allows you to quickly identify 3D features of interest by using the full processing power of your desktop.
Traditional methods of identifying features of interest such as building footprints, trees, power lines, and power poles were complex and time consuming due to the cost and time commitment of sending employees to remote locations to collect elevation and location information. ENVI LiDAR allows you to find features of interest utilising LiDAR data through either an automated feature identification tool or by manually editing and identifying features as you explore the data in a 3D visualisation. Feature identification can be performed on an entire point cloud scene, a user defined subset of a scene, or multiple LAS files simultaneously, providing accurate information in a fraction of the time. ENVI LiDAR utilises the detailed elevation information in LiDAR data to enhance your geospatial analysis.
Commonly identified features and products
The products you create with ENVI LiDAR feature identification capabilities are useful in a variety of industries, from utilities for determining vegetation encroachment on power lines, to defence and security for viewshed analysis, or even natural resource management to create forest inventories. Regardless of your application, ENVI LiDAR has the functionality you need to make informed decisions.

3D feature extraction results often need to be refined to ensure that individual features are accurately identified, or to correct attributes to ensure the visualisation is true-to-life. To refine results in ENVI LiDAR, fly through a realistic scene looking for specific data points or individual features that need editing. Editing features in ENVI LiDAR is easy; simply click specific data points and modify their identification. Refine DEMs by smoothing, fixing misclassifications, or refine results to include individual features such as: the shape of structures, the number of trees, and the location of power poles and power lines.
At any point during your analysis, ENVI LiDAR allows you to fly through 3D scenes in a realistic environment. View your data from every angle or even make adjustments to individual features.
After features are identified in your data scene, exporting those features as products or layers is useful for performing additional geospatial analysis, sharing with colleagues for verification studies, or inclusion in your GIS for mapping applications. ENVI LiDAR can export products and layers in a topographic format, as a standard raster, a .csv file, or in GeoTIFF, LAS, and SHP image formats.

The flexibility of ENVI LiDAR allows you to use exported results in a variety of geospatial tools like ENVI image analysis software or the ArcGIS® platform. ENVI software utilises scientifically proven algorithms to perform hyperspectral and multispectral image classification, feature extraction, change detection, and variety of other image analysis techniques. To perform additional analysis on your exported 3D products, ENVI LiDAR provides an easy to use direct link to ENVI that automatically opens ENVI and your exported file. When ENVI LiDAR products are used in conjunction with ENVI software, you can add more geospatial information to your analysis than ever before.
