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)

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)

Aerial Survey Tender Greece

Infoterra France and their Greek partner GEOMET Ltd have won a major contract, worth over €2.86 million, to deliver a significant quantity of fully orthorectified imagery and Digital Surface Models (DSM) covering Greek cities. The 18 month long project, which is the biggest venture of this type ever undertaken in Europe, kicked off with ADS40 linear scanners capturing images from June to end August 2007, followed by an initial delivery in October 2007. Final delivery will take place in September 2008. The VLSO or ‘Very Large Scale Orthophoto project', will cover 3500 square kilometres of all major to mid-size Greek... (read more)

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)

Airport Obstruction Survey

In early January, two cartographers from the National Geodetic Survey's (NGS) Field Operations Branch in Norfolk, VA, conducted an airport obstruction survey at the Miami International Airport for the Federal Aviation Administration (FAA). The survey, the first following a 12-month lapse in field survey operations, is being performed by NGS in an effort to maintain the ability to conduct aeronautical surveys. It also allows NGS to transition from primarily collecting survey data to providing Quality Assurance (QA) services of contracted survey data submitted directly to the FAA Geographic Information System program. QA services will continue to be the... (read more)

Geographic Information Market Survey

The Fraunhofer Institute for Computer Graphics Research IGD, Germany, is coordinator of the EU project HUMBOLDT, in cooperation with the Technical University Darmstadt. They are conducting a survey on the "Situation and Perspectives of the Geographic Information (GI) Market in Europe." This week, they are calling participants to respond to a survey. The EU project HUMBOLDT is especially focused on the harmonisation and integration of geospatial data within Europe. Standardisation efforts as well as European initiatives like INSPIRE and GMES are of major importance in this context. The focus of the survey therefore is set on general trends and perspectives...
