LP360 Rail Extraction Tools for LIDAR

The LP360 Rail Extraction tools for LIDAR data automatically extract a rail alignment (centerline) vector as well as classify “top of rail”. This feature is implemented as a semi-automated Point Cloud Task (PCT) and is available in the Advanced version of both LP360 for ArcGIS® and LP360 for Windows® (the standalone version of LP360). We recommend…

Multi-band Imagery and Bit Depth

Multi-band (multi-spectral) imagery, as the name suggests, contains multiple bands which make up the image as a whole. In remote sensing imagery, a band would be considered discrete ranges of wavelengths sampled by the system. If you recall from science class, a wavelength is “the mean distance between maxima or minima of a periodic pattern.”1…

Case Study: Southwest Florida Water Management District

Challenge Hernando County Florida needed to create a 3-D model of the City of Brooksville and turned to the Southwest Florida Water Management District (SWFWMD) office for help in getting the estimated building heights. Solution Because of LIDAR’s 3-dimensional qualities it is the perfect data source to extract building elevation information. This point cloud characteristic…

Automatic Building Extraction using LP360

Last month’s tool tip discussed using the Planar Point Filter to filter buildings from point cloud data. This month’s tool tip discusses building extraction, essentially the next step after creating a building filter. The Point Group Tracing and Squaring Point Cloud Task will allow you to further refine the point cloud data classified as building…
