EuroSDR Survey

Oblique Airborne Photogrammetry: Users' and Vendors' Views

Today, oblique airborne images are a powerful source of geodata, particularly for applications in urban areas. Although the cost of capturing is higher, object identification and creation of dense 3D point clouds is easier and more reliable compared to conventional vertical imagery. To better understand the current practice and possible user needs, the EuroSDR initiated a survey on the use and expectations of obliques. The questionnaire went online in spring 2014 and was targeted at both users and providers of hardware, software and services. Here, the authors summarise the key findings from the survey. In recent years, aerial multi-camera systems... (read more)

Survey Accuracy

Furthering Dialogue on ‘Towards Cadastre 2034’

Renewed debate on the nature and role of the cadastre was sparked in 2010 through the forums of FIG 2010 in Sydney, Australia, and GIM International. Six design elements for ‘future cadastres' were discussed, one of them being ‘survey accuracy'. The wide range of responses regarding this design element implied that the topic required further clarification. Here, we hope to provide such clarification and further the dialogue on ‘Towards Cadastre 2034'. The six design elements proposed to the FIG 2010 forum were: ‘survey accuracy'; the move towards property objects; implementation of 3D and 4D aspects; ability for real-time updates;... (read more)

Ordnance Survey Goes International

From September 2012, the UK geospatial information agency Ordnance Survey will be launching a new international organisation, Ordnance Survey International. It will harness the skills and expertise within Ordnance Survey to primarily support other national mapping agencies and countries. Ordnance Survey International will be headed by Steven Ramage, former executive director at the Open Geospatial Consortium (OGC), a global body developing open geospatial standards. The aim is to provide advice and services across the full spectrum of Ordnance Survey’s expertise, including data collection and maintenance, product development and geospatial data management. The advice will enable international customers to develop and... (read more)

UAS Campus Survey Project

Students Capturing Spatial Information Needs

Texas A&M University-Corpus Christi, home to the largest geomatics undergraduate programme in Texas, USA, is currently undergoing a major university expansion. Both the main Island campus and the Momentum campus, which is a smaller developing campus, are undergoing extensive construction projects. The university’s Conrad Blucher Institute for Surveying and Science (CBI) was tasked with devising a comprehensive way to capture the spatial information needs related to the expansion. This effort is ongoing and is being conducted by students, providing them with a unique survey experience. The initial task was to perform a complete ground survey of all existing infrastructure...

Finnish National Lidar Survey

Blom has been awarded a contract to provide Lidar data for the National Land Survey of Finland (NLSF). The total contract value is approximately NOK34 million over a period of four years. The contract is expected to be signed in January 2010, with start-up of the project at the beginning of second quarter of 2010. NLSF is responsible for production and maintenance of geographic- and real estate information in Finland. The purpose of the project is to create a new and accurate national height model covering an area of app. 120 000 sq.km.The dataset will also provide valuable information for... (read more)

Lidar-based Survey Solutions

Optech Incorporated

Optech Incorporated focuses on the development, manufacture and support of advanced, lidar-based survey solutions. Established in 1974 as a privately held, Canadian-owned research and development firm, Optech was originally an offshoot of research into light detection and ranging ('laser radar') conducted by its founder, Dr Allan Carswell, at York University in Toronto. In the 1980s Optech airborne lidar systems produced the world's first nautical charts based on airborne lidar data. In the early 1990s, ground-based Differential Absorption Lidar (DIAL) systems were installed at several Arctic sites to monitor stratospheric ozone. At the same time, the company developed the compact, versatile... (read more)

Victorian Rail Infrastructure Survey

Geomatic Technologies (GT) (Australia), with the Department of Infrastructure (DOI), has completed the Victorian Rail Infrastructure Survey and Pass Assets project. The project involved producing a register of assets associated with Victoria’s Rail Infrastructure, estimated to be worth $6 billion. The register was identified by the State Government as being a requirement following the rail privatisation process in the late 90’s. Geomatic Technologies was commissioned by the DOI, to conduct a state-wide survey of all rail infrastructure through Metropolitan Melbourne and Rural Victoria. GT utilised many survey techniques including photogrammetric drivers-view and digital geo-referenced track imagery, taken from equipment mounted... (read more)
