The LiDAR tools are located under a new "LiDAR" button in the ENVI display, located between the "Topographic" and "Radar" buttons. Currently, there are eleven tools:
| Get LAS File Info | - Displays header and projection information for an LAS file |
|---|---|
| Convert Ascii Data to LAS | - Converts text point data into LAS format lidar files |
| Rasterize Lidar Data | - Converts raw point data into various raster products |
| Add Projection to LAS File(s) | - Adds embedded projection information to LAS files |
| Reproject LAS File(s) | - Converts existing LAS files into a new map projection |
| Create Boundary EVF | - Creates an ENVI Vector File that shows the boundaries of the data |
| Perform Height Filtering | - Performs vegetation filtering on the data |
| Create Elevation Profile(s) | - Creates one or more elevation profiles along a user-defined transect |
| Buffer LAS Files | - Geographically buffers the data using neighboring files |
| Decimate LAS File(s) | - Decimates the points the data file |
| Subset LAS File(s) | |
| • Subset via Coordinates | - Subsets data files according to user coordinates |
| • Subset via Image/ROI | - Subsets data files using a reference image and/or regions of interest |
| Tile LAS File(s) | - Divides one or more files into multiple tiles |
| 3D Lidar Viewer | - An interactive viewer for displaying lidar point data |
