Somewhere Deep Inside

It is about thirty-five years since I left university with the Dutch equivalent of a MSc degree in Geodesy. Computers had just been introduced into our field and we were gaining some first experience in their use and an early understanding of what they would mean for our profession. We were exploring the possibilities of Doppler satellite measurements for positioning and navigation. But our education was still for a profession with a long tradition. The lifetime of surveying equipment was a multiple of the professional lifetime of a surveyor. Photogrammetric instruments required an investment of several annual incomes of a... (read more)

Deep Water Horizon at Rocket City Geospatial Conference

The fourth annual Rocket City Geospatial Conference (RCG) offers special sessions this year on key issues impacting the Southeastern United States. The conference will feature a special session on the Deepwater Horizon Oil Spill that affected the Gulf of Mexico earlier this year and continues to be one of the worst man-made disasters in history. According to the announcement, kicking off this session will be Dr. Amy Merten, chief, Spatial Data Team, Office of Response and Restoration, of the National Oceanographic and Atmospheric Administration (NOAA). Dr. Merten will be speaking on the Environmental Response Management Application (ERMA) project. She was... (read more)

GIS for Direction in Charity

1Spatial, UK, is delighted to announce that the company is entering a team in conjunction with Linknode for the 2012 Oxfam TrailTrekker challenge. Using the latest Windows phone technology, with the phones kindly donated on loan by Microsoft, Linknode will be providing its very own apps to aid navigation and record-keeping during the challenge. The ‘Heads Up Compass’ overlays heading and location onto photos for visible geotagging. The team will be also using a customised version of the ‘Where on Earth’ app which will provide information on the distance and direction to the next mile markers and checkpoints en route,...

Atlas: a Window on the World

This is an exciting time for cartography. The volume of available geographic information continues to increase, from diverse sources and providers each with their own characteristics and quirks. One of the best ways to consolidate such data is in an atlas. Atlases are visual windows on our surroundings. Whether they offer views of the entire world or focus on small areas of interest, atlases offer a unique geographic perspective. Atlas Information System Turning the page of a printed atlas allows the reader to discover and explore distant places. Atlas information systems operate as a focal point for use and dissemination...

USGS Releases New Lidar Base Specification

The U.S. Geological Survey National Geospatial Program (NGP) has released a new version of the USGS Lidar Base Specification (LBS) that defines deliverables for nationally consistent Lidar data acquisitions. This update – version 2.1 – of the Lidar Base Specification better aligns the specification with the Lidar data workflow in the USGS NGP, streamlines the data publishing workflow, clarifies language and addresses Federal requirements to use non-proprietary data formats.     3D Elevation Program The USGS Lidar Base Specification provides a common base specification for all Lidar data acquired for the 3D Elevation Program (3DEP) component of The National Map. The goal of the... (read more)

Leica Geosystems Takes Over Airborne Hydrography AB

Leica Geosystems strengthens its market position in airborne surveying through Hexagon’s acquisition of Airborne Hydrography AB (AHAB, Sweden), a provider of airborne laser survey systems for hydrographic and topographic surveys. Founded in 2002 and based in Jönköping, AHAB serves international survey companies and governmental organisations around the world, with hydrographic and topographic software and systems to map land, coastal zones and sea floors. Their product portfolio includes airborne bathymetric Lidar technology, which provides the equivalent of above-water topographic maps, enabling underwater objects to be detected and deep and shallow waters and coastal zones to be mapped and monitored. The AHAB... (read more)

USGS Establishes New 3D Elevation Programme

The U.S. Geological Survey (USGS), along with other federal, state, local and private agencies, is establishing a new 3D Elevation Programme (3DEP) designed to respond to the growing needs for three-dimensional mapping data of the United States. This co-ordinated partnership can help to meet the country’s needs for high-quality, 3D elevation data. Current and accurate 3D elevation data is essential to help communities cope with natural hazards and disasters such as floods and landslides, support infrastructure, ensure agricultural success, strengthen environmental decision-making and bolster national security. The primary goal of the 3DEP partnership is to systematically collect 3D elevation data across...

Will Artificial Intelligence Die Another Silent Death?

Artificial intelligence (AI) was first presented as a potential solution for object recognition some 50 years ago, but died a silent death along its winding road, writes Mathias Lemmens in his latest column. Now, big geodata is driving the need for automated mapping and reviving the interest in AI. But will the optimistic promises of deep learning come true this time? Never before in history have humans generated such gigantic volumes of geodata as we do today. The production of images and point clouds using a wide variety of geodata acquisition technologies is just one side of the coin; on... (read more)

GNSS Receivers for Difficult Environments

Aslanlar Insatt, a construction company specialising in infrastructure development, including highways, tunnels, dams, bridges and railways, has chosen the Ashtech ProMark 500 GNSS receiver to meet its GNSS survey needs. Aslanlar engineers compared four well-known brands in a series of head-to-head tests conducted in especially difficult, heavily shaded and multi-path, surroundings. Aslanlar was testing to find the receiver that would give them most precise 3-D coordinates for construction staking. The tests concluded that the Ashtech ProMark 500 consistently and significantly outperformed the competition in both accuracy and precision. Aslanlar chose to test in particularly difficult environments to ensure good operability... (read more)
