Our software product Laserdata Information System (LIS) is composed of the core package LIS Pro 3D and optional packages (a total of over 240 tools). LIS is an extension to the free and open source GIS SAGA, providing tools for enhanced 3D point cloud data processing. The software is completely modular, fully automatable (scripting, model builder, C++), is running on 64 bit GNU/Linux and Windows operating systems, and supports parallel processing (true multi-threading).
This core package is made up of ten tool libraries providing a comprehensive set of more than 100 tools for point cloud and geospatial data visualization, processing and analysis. Inspect your data in 3D or enrich it with derived information. Applications include profile extraction, smart point cloud thinning, DTM / DSM / nDSM creation, colorization and gridding of point clouds, and difference and volume calculations.
The package contains tools for the automatic classification of high-density laserscanning data (MLS/TLS) into the classes ground, walls, roofs, trees and poles. Applications are map layers (e.g. locations of trees and poles) and road inventories.
The package contains tools for structural geology, including tools to derive the bedding orientation from lineaments, to create pole plots, to derive discontinuity sets and joint planes, to calculate joint spacings, and to perform kinematic failure analyses. Applications are slope stability analyses and the derivation of block sizes.
The package contains tools for the automatic delineation of building footprints (LOD0) and building models (LOD1 and LOD2) from point cloud data. Applications are map layers and 3D city models, which can be enriched with further information.
The package contains tools for forest masking, crown coverage computation, single tree derivation, tree shape metrics, creation of 3D vector models of trees and volume calculations (biomass, stem volume). Applications include silvicultural analyses and management and the creation of map layers for tree cadastres.
The package contains tools to derive terrain breaklines and to calculate surface roughness and local morphometry features like slope, aspect, curvature and shadings from point clouds. Applications are digital terrain analysis and mapping products.
The package contains tools for point cloud and image registration and orientation, including a 3D point cloud registration editor, and tools for the derivation of transformation matrices and iterative closest point adjustment (ICP). Applications are the registration of multiple scan positions and the reconstruction of camera poses (supporting the lense types telephoto, panorama and hemisphere).
The package contains a 3D point cloud editor which allows you to relabel point cloud attributes and to delete points. It also supports the fitting of a plane to selected points in order to derive the 3D orientation. Besides, manifold visualization options for point clouds, raster data sets and 3D shapes are provided. Applications are the manual improvement of filtering and classification results or the digitization of joint planes (structural geology).
The package contains six tool libraries with over 50 tools for point cloud and raster data storage, access, and processing in a PostgreSQL / PostGIS database. Applications are the storage and seamless access to large amounts of data, from single projects to nationwide coverage.
The package contains tools for the in-depth analysis of point cloud data like 3D distance measurement between two point clouds, positional accuracy estimation, the calculation of various point features by neighborhood analysis (including height features, density features, local plane features and Eigenvalue features), statistical analyses and fuzzy c-means clustering.
The package contains tools for the delineation of line and polygon vector representations from point cloud data. Applications are the extrusion of shapes and the derivation of skeletons and polygonal 3D shapes from point cloud segments.
The package contains a comprehensive set of point cloud segmentation and region growing tools, each dedicated to specialized tasks. Applications include the segmentation of point clouds by robust plane or line fitting and the segmentation of ground, building and vegetation points.
The package contains tools for supervised and unsupervised point cloud classification, including the derivation of geometric primitives like lines, planes and volumes, and the classification of point clouds into the classes ground, building, vegetation, power lines and pylons.
The System for Automated Geoscientific Analyses (SAGA) is a well known free and open source GIS, providing a comprehensive
set of processing tools for raster and vector data. We are contributing to the project on different levels being
part of the SAGA GIS development team, maintainer of the project web page and user forums, and funding member of
the SAGA User Group Association.
We provide professional services for SAGA, including consultancy, automation (scripting) and tool development.
Most of the project resources are hosted on sourceforge, including binaries, source code, documentation/tutorials, user forums, wiki and bug tracker. Besides that, additional information like references (documentation, research papers, API reference, tool reference) can be found on the project's homepage.
