UAS Survey of Rapa Nui

Capturing 164 Sq Kms of the World’s Most Remote Inhabited Island
Unmanned aerial systems (UASs) can be easily transported and this beneficial feature is ideal for photogrammetric surveys of remote spaces. Rapa Nui (Easter Island), the most isolated inhabited place on the planet, took UAS photogrammetry to the limit because of cloud cover, windy weather conditions and the vast size of the island. The resulting orthoimagery and digital surface models will support archaeological documentation and research. The archaeological features will be archived in a single, detailed database. The authors discuss this exciting and challenging adventure. The existence of Rapa Nui was first recorded in European annals by Jacob Roggeveen. The Dutch... (read more)

Ordnance Survey Announces GPS Devices

Ordnance Survey (OS) has announced the launch of four new off-road OS GPS navigation devices for walking, hiking and off-road cycling. The innovative GPS units are a first for OS, and have been designed for ease-of-use straight out of the box. They boast the trusted accuracy that you would expect from OS, combined with advanced performance features. Covering the areas you choose, each device comes with up to 12 tiles of OS’s leisure mapping, giving access to up to 8,000 km2 of continually updated maps in either 1:50,000 or 1:25,000 scale. Durable and water resistant, the devices come with features... (read more)

New Book: ‘GNSS Survey & Engineering’

Geomares Education introduces a new book, called ‘GNSS Survey & Engineering’, written by Huibert-Jan Lekkerkerk. 'GNSS Survey & Engineering' is aimed at providing the everyday professional GPS user with enough background information for the understanding and correct operation of satellite navigation equipment in general and particularly GPS. The new book is based on the lectures the author has written for the Skilltrade course in hydrographic surveying as well as a series of articles on satellite navigation systems. Today, GPS is almost synonymous with simple navigation and positioning in nearly all sectors. There are many brands and models to choose from... (read more)

News from The Survey Association

In this article we are featuring news from The Survey Association (TSA) and this will be followed up by regular columns. The TSA conference was held in November and we include a report on this as well as information on the government apprentice scheme and a TSA Guidance note on PAS128 compliant utility survey. The annual Survey Association (TSA) conference was held this year at the Steam Museum of The Great Western Railway in Swindon, an appropriate venue to match the theme of 'On the Right Track'. The tone for the day was set by Chris Preston of Network Rail by... (read more)

Position Partners Announces Total Survey Systems Acquisition

Position Partners, national geospatial solution provider, has announced the acquisition of Total Survey Systems, the distributor for Sokkia measurement instruments in Australia. The acquisition will see all of Total Survey Systems’ staff join the Position Partners NSW team in their Silverwater office. “Surveyors in New South Wales have never been more in demand. They will expect systems and support to be even more productive as geospatial data exponentially increases. We are pleased to be able to extend the support to our mutual customers with a larger, highly experienced team and a wider range of solutions to suit every application,” said... (read more)

Ordnance Survey Add Electricity Pylons to Map

At Ordnance Survey we often talk about the 10,000 changes a day being captured in our database containing all of the features of Great Britain. It can be hard to grasp how that much change is taking place – until you think about all of the new roads and buildings under construction and then burrow down into the level of detail we capture – right down to phone boxes and even electricity pylons. When National Grid announced that the first new electricity pylon design in 90 years was going to be erected in Nottinghamshire, we knew our surveying team would... (read more)

Bluesky Completes UK and Ireland Survey Season

Aerial mapping company Bluesky has completed another survey season in the UK and Ireland. Capturing around 70,000 square kilometres of aerial photography – of which about 70% is high resolution – the total area flown equates to around twice the size of the Netherlands. This year was marked by using an innovative hybrid airborne sensor combining vertical and oblique imagery together with 3D laser scanning. In addition to the true ortho photography, which is used to create 3D height models of the earth’s bare surface (Digital Terrain Models / DTM) and ground features including buildings and trees (Digital Surface Models...

3D Laser Scanning for Topo Survey

A recent project carried out by J Breheny Contractors on behalf of Cambridge University showcases the economics of using a high definition 3D laser scanner for topo surveying. The rate at which geospatial technology is changing is increasing, and with it, our ability to collect more data more rapidly. 20 years ago it would have taken several seconds and possibly minutes to get a single point using GPS; today we can collect one million points per second using a 3D laser scanner. The methodologies and workflows of data collection by total station, GNSS, video, images, laser scanning, terrestrial and mobile... (read more)
