Automatic Ground Classification of Dense Point Clouds in LP360

The density of point clouds (usually expressed as points per square meter) is increasing on what seems to be a monthly basis.  This is particularly true of point clouds derived from Dense Image Matching (DIM), the clouds produced from software such as PhotoScan, Pix4D, DroneDeploy and so forth. You can quickly check the density of…

Raster Bit Depth

GeoCue, Terrasolid and LP360 can all output Raster files with different Bit Depths. The bit depth (sometimes called pixel depth) of a cell determines the range of values that a particular raster file can store, which is based on the formula 2n (where n is the bit depth). For example, an 8-bit raster can have…
