Esri Launches New Living Atlas Innovations to Revolutionise Digital Twin Technology

An interesting range of new uses for GIS around the world were celebrated at the 38th annual Esri User Conference in San Diego, California, held from 9-13 July. The Esri UC is a key global event for users of the company's technology who are changing their organisations as well as the world around them. One particular set of innovations showcased were updates to ArcGIS Living Atlas of the World, the foremost collection of geographic information from around the globe. These updates included new data and capabilities for users to gain unprecedented insights to help in decision-making as well as a more... (read more)

Twin Galileo Satellites Ready For Launch

The twin Galileo satellites are fully fuelled and mated together atop the upper stage that will haul them most of the way up into their final orbit. The launch is now planned for the evening of 12 October 2012 from the European Space Agency’s French Guyana launch site. Technicians donned protective suits to fill the two satellites’ tanks with hydrazine fuel, used to maintain the satellites’ attitude and orbital position during their planned 12-year lifetime. Rather than carry a significant amount of extra fuel to insert themselves into their planned orbits – like typical telecommunications satellites or Galileo’s US GPS equivalents...

Digital Norway

Co-operating to Up Geo-information Use
Digital Norway is a collaboration that is playing an important role in implementation of the national spatial data infrastructure in Norway. At the root of the infrastructure is a national geoPortal enabling access to geoinformation data and services owned by producers at national, regional and local level. A sophisticated internet application has been developed to facilitate regional access for a broad range of new GIS users. Technological development is today moving rapidly from desktop GIS towards distributed GIS, leading to increased use and new users and allowing realisation of the full potential for geo-information. Recognising these areas of potential growth... (read more)

Digital Aerial Cameras

New Developments
The growing need for geo-data everywhere is driving customers to demand shorter turnaround rates and higher levels of detail. These needs can be met by aerial imagery directly captured in digital format onboard an aircraft. In tandem with the new product survey on Digital Aerial Cameras (see our website), the author here gives an overview of new developments. In my overview published in GIM International April 2008, I categorised the various digital aerial cameras under linear- and area-array solutions: one of many possible groupings for these systems. Another, based on technological criteria, considers dimension (size, weight and number of pixels... (read more)

Digital Map of Denmark

The full digital map of Denmark is available for commercial use. Denmark is the seventh Western European country for which the mapmaker has developed a navigation map. The map contains 140,000 kilometrers of roads and almost 7,000 cities and villages.     AND is accelerating its efforts to fully map Western Europe, following an agreement made earlier this year with a large American online company, for the use of AND's maps of Western Europe.     (read more)

Digital Angular Measurement

Place the instrument on a tripod, level the bulbs and push the button and the display shows the present angles H+V. Angle measurement: <i>I know what it is, I know what it does, but how does it work?</i> Up until a few decades ago surveyors had to rely on optical-mechanical components for accurate measurement of horizontal and vertical angles. Glass circles were divided by thin marks, a nonius unit made possible interpolation for improved accuracy and small mirrors brought the necessary daylight into the heart of the instrument. The operation of such instruments required specialised knowledge and computations such as... (read more)

USGS Maps Go Digital

“US Topo” is the next generation of topographic maps from the U.S. Geological Survey. Digital US Topo maps are designed to look, feel, and perform like the traditional paper topographic maps for which the USGS is so well-known. However, in contrast to paper-based maps, US Topo maps provide technical advantages that support faster, wider public distribution and enable basic, on-screen geographic analysis for all users. “The public’s high regard for USGS topographic maps stretches over a century,” said Secretary of the Interior Ken Salazar.  “Because Survey maps consistently describe our nation’s entire landscape, they are the standard mapping reference for...

Digital Floor Plans

Enabling Better Facility Management
Interest in surveying the inside of buildings is on the rise as computer-run digital floor plans are increasingly adopted for facility management. This is causing architects and surveyors alike to move away from blueprints towards Computer Aided Design (CAD). The authors describe a successful test for rapid creation of floor plans of a newly constructed building using simple measuring devices and a recently developed software tool. The test site was on the campus of Nyiregyhazi Foiskola, a university in eastern Hungary which maintains its buildings and other facilities using Computer Aided Facility Management (CAFM) based on the CMMS (Computer Maintenance...

Digital Mapping Camera Conference

More than 50 leading aerial mapping company representatives and Intergraph Digital Mapping Camera (DMC) users from twelve different countries in Europe, Africa and the Middle East met for the fourth annual Intergraph European Digital Mapping Camera User Forum. At the event, attendees heard from industry leaders and learned more about producing high-resolution digital aerial images.   The user forum, held 26 and 27 January in Münster (Germany) featured keynote speaker Dr. Karsten Jacobsen of the Institute of Photogrammetry and GeoInformation at the University of Hanover. Dr. Jacobsen presented a comparison of "GSD versus true GSD" and why specially designed camera... (read more)
