Lidar data processing tools focused on Spanish PNOA datasets

Herramientas para procesado de datos Lidar del PNOA

Lidar PNOA: https://pnoa.ign.es/el-proyecto-pnoa-lidar

Introduction

CartoLidar es una colección de herramientas destinadas a procesar ficheros lidar (las y laz) para clasificar los puntos y generar ficheros ráster con DEM y DLVs.

DEM (Digital Elevation Model): modelos digitales de elevaciones (MDT, MDS) DLV (Daso Lidar Variables): variables dasoLidar, que representan diversos aspectos de la estructura de una formación arbolada, arbustiva o de matorral.

CartoLidar también proporciona herramientas adicionales para generar otros productos de utilidad en selvicultura y otras areas de gestión del medio natural a partir de los ficheros ráster con las DLVs.

El proyecto está en fase alpha e incluye únicamente la herramienta "clidtwins".

clidtwins está destinada a buscar zonas similares a una(s) de referencia en términos de determinadas variables dasoLidar (DLVs).

CartoLidar is a collection of tools to process lidar files "las" and "laz" and generate other products aimed to forestry and natural environment management.

This project is in alpha version and includes only the "clidtwins" tool.

"clidtwins" searchs for similar areas to a reference one in terms of dasoLidar Variables (DLVs) DLV: Lidar variables that describe or characterize forest structure (or vegetation in general).
