# pklas2img(1)

Rasterize LAS/LAZ point clouds with filtering/compositing options

## NAME

pklas2img - Rasterize LAS/LAZ point clouds with filtering/compositing options

## SYNOPSIS

**pklas2img**  **-i** *lasfile* **-o** *output* \[*options*\] \[*advanced options*\]

## DESCRIPTION

**pklas2img** converts a las/laz point cloud into a gridded raster dataset. The implementation is based on liblas ⟨http://www.liblas.org/⟩ API. You can define the bounding box, grid cell size and spatial reference set. The composite rule for multiple returns within a single grid cell can be set with the option FC**-comp**F\[0\]. The default attribute is z (height), but can also be intensity (if available), the scan angle rank (FC**-n**F\[0\] angle), the return number (FC**-n**F\[0\] return) or the total number of returns in that grid cell (FC**-n**F\[0\] nreturn). To select specific returns only, set the option FC**-fir**F\[0\] (first, last, single, multiple, or all).

## OPTIONS
