DJI’s Metric Camera for Aerial Surveying

DJI has released the X4S camera, a lightweight version of the large aerial cameras carried in manned aircraft. How do aerial or metric cameras differ to a DSLR? An aerial mapping camera is primarily designed to have a low distortion metric lens and reliable construction to maintain its calibration. To achieve this the cameras have very few moving parts, particularly those that would affect the lens focal length. Aerial camera lenses are very high quality and virtually distortion free. This, and a constant lens focal length, means that every pixel is in the right place. 3D mapping from photogrammetry is based on... (read more)

Photogrammetry Tool for UAV Land Surveying Missions

Before the introduction of small unmanned aerial vehicles (UAVs) for aerial photogrammetry, planes, helicopters and metric cameras were used. Aerial mapping projects were often not only costly, but also complex due to the images being taken from high altitudes. UAVs have provided more affordable and faster aerial mapping solutions. When it comes to planning survey missions for small UAVs, UgCS is suitable software for the job. It supports most UAV platforms and provides useful tools such as a photogrammetry tool and an image geotagging tool. The photogrammetry tool in UgCS (designed by SPH Engineering) allows creating and flying photogrammetry missions... (read more)

CGD Ltd Wins Pershore Abbey Surveying Contract

Worcester based chartered land surveying practice CGD Ltd has been appointed to undertake a surveying project at a former Anglo Saxon Abbey in the county. The project involves surveying and measuring every stone at the Abbey, using the latest 3D scanning technology; the final data will then be processed to produce a 3D model which will be shared with the Abbey’s architect. Due to the density of measurements over a given area, the 3D laser scanner can survey building features in incredible detail. Plans can include accurate measurements of intricate building features that were notoriously hard to survey using traditional... (read more)

Surveying Profession in Transition - FIG Congress 2018

James Kavanagh has given a report on the FIG Congress with particular reference to UK interests. Here we look at some of the wider issues from the technical sessions. Surveying is Transforming The congress provided an overview of the surveying sector as a whole, which is steadily transforming to meet future requirements. Although the precise circumstances vary from country to country, many of the presentations expressed the establishment of an open real-estate market as a common requirement in a globalised economy. Whereas the surveying market has been traditionally local and national by nature, and the professionals within the countries have... (read more)

SBG Systems Launches Horizon IMU for High Performance Surveying

SBG Systems has released the FOG-based Horizon inertial measurement unit (IMU), designed for high demanding surveying applications such as high-altitude data collection, or mobile mapping in very dense areas such as urban canyons. Navsight Land/Air Solution consists in a ready-to-use inertial navigation solution dedicated to surveyors for mobile data collection. It is available at different levels of accuracy to meet the various application requirements and can be connected to various external equipment such as an odometer, Lidar, etc. Navsight Land/Air Solution already offered two levels of performance with the Ekinox and Apogee IMUs. These MEMS-based IMUs provide most surveying markets... (read more)

Association to Promote Aerial Surveying in Europe Announced

Some of the leading names in European aerial mapping have come together to create a new association promoting the benefits of aerial surveying to the wider commercial and government sectors. Similar in concept to MAPPS (the national association of firms in the surveying, spatial data and geographic information systems fields) in the USA, the European Association of Aerial Surveying Industries (EAASI) was incorporated on the 6 June, followed by the first Association Board meeting. In attendance were Simon Musäus, Senior Vice President of COWI, who was elected as EAASI President, André Jadot, CEO of Eurosense who was appointed Vice President,... (read more)

Trimble Introduces Android Application for Field Surveying and Data Collection

Trimble has introduced Penmap for Android, a cloud-connected application for field surveying and high-accuracy geographic information system (GIS) data collection that works on mobile handhelds, smartphones and tablets. Trimble Penmap focuses on core survey and mapping tasks such as cadastral and boundary surveys, establishing local control, stake-outs, quality checks and asset management for utilities. It provides both professional surveyors and field workers with an intuitive, easy-to-use map-based interface to manage features and attributes for high-accuracy GIS and complete survey documentation. For example, the application is ideal for use in the energy distribution industry for locating infrastructure and recording critical information... (read more)

Hydrographic Surveying in the Wake of Hurricane Irma

Phil Payne gives a personal account of his experience in the Caribbean at the time of Hurricane Irma. He reminisces on the usefulness of basic techniques when the latest systems are, for whatever reason, not available, especially after being in the eye of one of the most powerful hurricanes ever recorded, and thinks that in the circumstances he is justified to say that no two days are the same. Organising equipment contracts, the hire of a suitable vessel, and bringing people together in a foreign country is never an easy task, but come September last year I was ensconced in... (read more)
