Geoinformation Software as a Service

From Licensing to Subscription
Accurate geoinformation about urban areas, public buildings or historical sites is in great demand. It has become astonishingly easy to capture these scenes through cameras or laser scanning or to acquire open data from a diversity of sources. Professionals without a surveying background can do the job, but such professionals require reliable, robust, easy-to-use and affordable processing tools. Today, cloud computing can meet that need, enabling users to work with software packages running on remote servers on either a pay-per-use or a subscription basis. This article presents a cloud computing service dedicated to geoinformation software. Storing data in the cloud... (read more)

A Brilliant Career

GIM International interviews Gottfried Konecny
Professor Gottfried Konecny, one of the most respected names in photogrammetry, shares some reflections on his work and profession. He worked in post-war Neumarkt as a teenage draughtsman, was chief surveyor on the 1965 Canadian Mount Kennedy expedition, mapped the lunar landing site at NASA, and has been involved in nearly all the European space mapping missions. And these are just some of Professor Gottfried Konecny’s extraordinary achievements. Today emeritus professor at the University of Hannover, he shares withGIM Internationalsome of the highlights of a career in photogrammetry that has spanned well over six decades.<P> Why did you choose a...

Official Geoid Undulations Model

Substitute for Nationwide Orthometric Control Network
The classical geodesist’ dream of a dense, accurate, reliable and homogeneous countrywide levelling control network is a luxury even for the richest countries and will probably remain a dream. Prior to the GPS era there was no alternative to precise levelling. Now there is. The authors suggest a new approach to orthometric height control in which the best available geoid model is used as official, statutory model from which to deduce countrywide orthometric heights, while ellipsoidal heights are measured with GNSS. Developing countries may benefit. A geoid model is prerequisite for deriving orthometric heights from GNSS measurements. But is it... (read more)

2014 ASPRS Fellow Award Winners Announced

Bon A. Dewitt, Rongxing Li, Richard A. Pearsall, Karen L. Schuckman and Douglas A. Stow have been named the 2014 ASPRS Fellow Award winners. The ASPRS designation of Fellow is conferred on active ASPRS members who have performed exceptional service in advancing the science and use of the mapping sciences (photogrammetry, remote sensing, surveying, geographic information systems and related disciplines). The designation of Fellow is awarded for pro­fessional excellence and for service to the Society. Candidates are nominated by other active members, recommended to the Fellows Committee, and elected by the ASPRS Board of Directors. Up to 0.3 percent of... (read more)

Robotic Theodolites (RTS)

Measuring Structure Excitation
Robotic theodolites, the new generation of the well-known surveying theodolite, are used to measure deflections in short-span bridges with millimetre accuracy. This permits the coming true of an old dream for engineers: to be in a position not only to predict, but to measure the excitation of engineering structures due to dynamic loads such as wind and traffic, and hence evaluate their structural health.     Electronic theodolites or total-stations (TS) are very common survey instruments used to compute the Cartesian coordinates of selected points marked by a usually prismatic reflector. A TS emits a modulated IR ray to the... (read more)

Intergeo 2007

Knowledge and Action for Planet Earth
2007 marked the thirteenth consecutive annual Intergeo. The venue for this major conference and trade-fair for geodesy, geoinformation and land management, held this year from 24th to 28th September, shifts from year to year, always within the boundaries of Germany. This time the train stopped at Leipzig. The event is organised by HINTE GmbH in association with the German Association of Surveying (DVW), and this year took place in conjunction with the fifty-fifth German Cartographer's Day. The event made clearer than ever that geo-data acquisition is a booming industry. All things considered, including current financial figures, vendors of data acquisition... (read more)

Land Administration in Estonia

Since Estonia gained independence in 1991, huge efforts have been made to re-establish private property. Technologically speaking, land reform and land administration are a success; nearly the whole country has been registered and information on individual parcels can be disseminated to institutions and the general public via the web. However, lack of transparent land policy incapacitates the system from optimally serving land-management aims.<P> What are the main goals of land administration in Estonia During the nineties the main goal was land reform, with the political and economic goal of re-establishing private property. Land reform was the focus of attention for... (read more)

Underscoring Benefits to Humanity

GIM International interviews Orhan Altan
Professor Orhan Altan, recently appointed president of the ISPRS, the international NGO representing more than a hundred nations and regions across the globe, believes the organisation should prioritise environmental monitoring and sustainable development and so contribute to achieving the Millennium Development Goals. International co-operation, says Altan, for advancement of knowledge, research, development and education in this field, would be boosted by greater publicity for ISPRS scientific achievements and successes and their translation into universally understood language. We asked him about his expectations and dreams as head of one of the most important bodies in the geomatics industry, and the legacy... (read more)

ASPRS Honorary Members Selected

Clifford W. Greve and Vincent V. Salomonson have been selected as the next Honorary Members of the American Society for Photogrammetry and Remote Sensing (ASPRS). Their nominations were recently approved by the ASPRS Board of Directors. This is the highest award bestowed by ASPRS and there can be only 25 living Honorary Members of the Society at any given time. Initiated in 1937, this lifetime award is given for professional excellence in recognition of individuals who have rendered distinguished service to ASPRS and/or who have attained distinction in advancing the science and use of the geospatial information sciences. Greve and... (read more)

Managing Massive Point Cloud Data: Performance of DBMS and File-based Solutions

Today, Lidar and photogrammetry enable the collection of massive point clouds. Faced with hundreds of billions or even trillions of points, the traditional solutions for handling point clouds usually underperform. To obtain insight into the features affecting performance, tests have been carried out on various systems and the pros and cons have been identified. (By Oscar Martinez-Rubi, Peter van Oosterom and Theo Tijssen, The Netherlands) Point clouds have traditionally been processed into grids, vector objects or other types of data to support further processing in a GIS environment. Today, point clouds are also directly used for estimating volumes of complex objects,... (read more)
