Applanix Releases POSPac AIR 4.3 Software for Airborne Data Post-processing

Applanix (Canada) has announced the release of POSPac AIR 4.3, the latest update to its airborne data post-processing software. Developed for the aerial survey and remote sensing industry, the customided software incorporates a series of application-specific tools for systems using the company’s POS AV (Position and Orientation System, Airborne Vehicles) Direct Georeferencing technology. Application-specific toolsets include Photogrammetry Tools for system calibration and quality control of Direct Georeferencing for frame cameras, DSS Tools for mission management and image development of DSS imagery, and SAR Processing Tools for use with Synthetic Aperture Radar. New to the Photogrammetry Tools is an Automatic Tie-point... (read more)

Point Clouds (2)

Survey of Processing Software
Collecting and processing point clouds has been trending topic in the geospatial sector over the past few years. This article focuses on point cloud processing software aimed at creating DEMs or DSMs and products derived from these. The first article of this diptych, originally published in the June 2014 issue of GIM International, focused on functionalities. This survey starts with the software of Terrasolid, which is based in Helsinki, Finland. It will then focus on three systems listed on the Geo-matching.com website, subsequently continuing with software which operates independently from the particular sensors, to then arrive at proprietary systems. It... (read more)

Point Clouds (1)

The Functionalities of Processing Software
Whether based on Lidar, photogrammetry, radar, sonar or other remote sensors, systems for geodata acquisition create millions or even billions of 3D points. To be useful, the data needs to be organised, combined, georeferenced, measured and analysed, and that in turn requires software. This article first defines what point clouds are and identifies their sources. It then goes on to examine software functionalities such as visualisation and editing. The July 2014 edition of GIM International will be a themed issue covering collection and processing of point clouds and hence will include a selection of the many software packages currently available....

Data Lineage

An Essential Step in Data Processing
As William Pollard said, "Information is a source of learning. But unless it is organised, processed, and available to the right people in a format for decision making, it is a burden, not a benefit." In any project it is essential to distribute information to all parties involved. Reproducible project process information is essential to all participants at every working level. Information should be organised and presented in a standardised, easy-to-use way, possible using data lineage. View Larger Map Project information is expected to contain answers to essential questions such as: how, what, when, where, why and who? The answers... (read more)

Lidar Quality Assurance

Open-Source Software For Processing Lidar Point Clouds
Basic tools for processing Lidar point clouds, which can be extended depending on needs, provide a flexible platform for service providers and users alike. Here, the authors demonstrate how a publicly available open-source application with basic tools for visualising, editing and analysing Lidar point clouds has been extended into a compliant platform that serves diverse applications including mapping of power-line corridors, land uses and riverbeds. The platform, called DielmoOpenLiDAR and released under the GNU GPL licence, enables management and display of massive Lidar datasets together with vectors, rasters, OGC services such as WMS, WFS, WCS and other geoinformation. For professional... (read more)

Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. This article describes normal variation analysis (Norvana) segmentation – an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as... (read more)
