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)

MicroSurvey Point Cloud CAD 2010

The Point Cloud CAD 2010 is Microsurvey's latest product that allows the individual to work with Point Cloud and LIDAR data with ease. MicroSurvey has spent the last year working with Leica Geosystems on creating a product called Leica ForensicMAP and in doing so saw a need for the Civil Engineering and Land Surveying sectors and created the Point Cloud CAD 2010.  Microsurvey's system allows with the powerful Point Cloud Engine to work with hundreds of millions of points with ease and the ability to create line work very quickly, surface models and contours directly from the Point Cloud.Point Cloud...

Linking GIS and the Cloud

The recent news that the US federal government is looking to purchase cloud-based services with an estimated value of USD2.5 billion should be enough evidence to change the mind of anyone who still thinks that the cloud will float by. Moving data, software and services to the cloud is happening and the pace of this change will only increase. Arc2Earth, New Jersey, USA, clients are at the vanguard of the ‘geo-cloud' and the Arc2Earth software is used throughout the world. New Jersey-based Arc2Earth has been working at the interface of GIS and the web since 2006, creating products that bridge... (read more)

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)

Columbus 4 Redesigned for Cloud Use

Best-Fit Computing (USA) has released Columbus 4, its web-based least-squares network adjustment software product. Featuring a completely redesigned and simplified user interface, it facilitates access to Columbus anywhere, anytime using an internet browser. Powered by Amazon.com's cloud infrastructure, users have the comfort of always working with the latest version.   Columbus 4 features a robust, geodetic-based adjustment engine. This eliminates mathematical distortions of both small and large projects, allowing Columbus 4 to support projects that span any distance. Geoid modelling is handled in the cloud, so there are no more grid files to manage. Users can optionally store data in... (read more)

Cloud Will Dominate the GIS Environment

Cloud computing is on everyone's lips. And the same goes for Intergeo, which is taking place from 9 to 11 October 2012 in Hanover, Germany. Key topics at Intergeo, such as capturing, processing, archiving and presenting data, can be made available on an entirely new basis using cloud computing, unlocking a range of uses and making them more accessible to new user groups who have found existing solutions too complex and ultimately too expensive. Otmar Didinger, president of the Rheinland-Pfalz Regional Authority for Surveying and Geoinformation, on how the cloud can benefit users as it solves the issue of how... (read more)
