Insight into Point Cloud Software

To be useful, the millions or even billions of 3D points generated by a variety of active and passive sensors need to be stored, organised, combined, georeferenced, measured and analysed, and these tasks all require software. That the storage of billions of 3D points is an issue in itself is shown in the article by Martin Kodde in the July 2014 issue of GIM International. (By Mathias Lemmens, senior editor, GIM International) The LAS storage format, initially developed for airborne Lidar, has become a de facto standard. The more generic E57 format based on XML supports meta data, 2D imagery... (read more)

Techniques for Ash Cloud Mapping

An ash cloud from the Islandic volcano Eyjafjallajokull blocks the air traffic in parts of the UK and northern Europe. The UK Met Office has made available methods used for measuring and mapping the ash cloud, and predict it in the near future. Dust and ash can be measured by satellite, Lidar, weather balloons, aircraft and photometers to name a few. Each method of measuring has its own characteristics, pros and cons. They are described and observations of the UK are displayed on a map.A dedicated volcanic ash detection tool facilitates distinguishing an ash cloud from water-containing clouds. The collection of...

Background to Point Cloud Software

To be useful, the millions or even billions of 3D points generated by a variety of active and passive sensors need to be stored, organised, combined, georeferenced, measured and analysed, and these tasks all require software. That the storage of billions of 3D points is an issue in itself is shown in the article by M. Kodde (Page 16).The LAS storage format, initially developed for airborne Lidar, has become a de facto standard. The more generic E57 format based on XML supports meta data, 2D imagery and a broad pallet of point attributes. Nevertheless, proprietary formats are often preferred as... (read more)

Survey and Point-Cloud Software

Virtualgeo
Virtualgeo was established in 1994 as a spin-off from an established survey company active in the field of topographic survey and infrastructure planning since 1985. Virtualgeo has three offices in Italy, headquarters in Sacile and branches in Venice and Terni.<P> The company focuses on advanced technological services in the fields of cultural heritage, particularly architectural and archaeological, and the environment. The evolution of techniques for data acquirement and representation, together with our need for “made to measure” software to improve productivity, have pushed us into investing heavily in research and development. Our organisational structure is arranged around the supply of... (read more)

Machine-learning Point Cloud Classification

Pix4Dmapper is an industrial-standard photogrammetry software package that provides accurate 3D reconstruction from overlapping images. Along with the expanding drone market, people are keen to explore new solutions to replace or to complete traditional technologies. Point cloud classification, an iconic feature for Lidar point cloud, is now also being considered by drone surveying professionals. While Lidar provides up to four returns and gives precise and clean 3D points, the quality of photogrammetry points is based mostly on image content. It is more challenging to classify photogrammetry point cloud than the Lidar point cloud. However, with the advancement of platforms and... (read more)

Downtown Dublin as a Lidar Point Cloud

A Highly Accurate, Diverse and Dense Annotated Laser Scanning Dataset of a City Centre
The advance of Lidar data acquisition technologies is substantially increasing the amount of spatial data obtained and it is becoming cost-prohibitive to process it manually. Artificial intelligence (AI) has now started to offer cost-effective solutions to analyse and utilize those big datasets. AI can be employed for scene understanding, accurately detecting objects and classifying 3D assets. These are the significant fundamentals of several applications including autonomous navigation, intelligent robotics, urban planning, emergency management and even forest monitoring. The most popular types of 3D spatial information for such applications are Lidar and imagery data. This article describes the dense annotated ground-truth... (read more)

Point Cloud Streaming Service at Intergeo 2013

Gexcel (Italy) is launching a new point cloud streaming service based on a web application. It will launch this application during Intergeo, to be held from 8 to 10 October 2013 in Essen, Germany. The service allows the upload of point clouds generated using Gexcel R3 or the Gexcel R3 streaming software to a remote server. Gexcel R3 can import data directly from the most common point-cloud data formats, E57 included. Massive Point Clouds loaded in the service servers can be visualized and navigated in Chrome or Firefox using a standard 64 bit PC. This service, based on an easy... (read more)

SimActive Enables Processing in the Cloud

Photogrammetry software developer SimActive has announced that processing in the cloud is now officially supported by Correlator3D. Users can subscribe to an online computing service, such as Amazon EC2, and run Correlator3D on a virtual machine.  Correlator3D is a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including UAVs. The main advantage of procesing in the cloud is the capability to use multiple licenses as required. It permits an on-demand deployment of the software on several processing machines, without any computer hardware. The new option allows customers to continuously adjust their processing...
