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)

Calibrating Survey Instruments

A Modern Calibration Bench

The geomatics profession is implicated in several ISO standards. The important ISO9001: 2000 prescribes regular instrument testing and calibration. To help meet required stringent alignment tolerances, a modern calibration bench has been developed for the calibration of survey instruments under internationally recognised COFRAC accreditation. Surveyors must as professionals fulfil certain legal, regulatory and/or accuracy requirements for their clients. They will typically strive to do so in an optimally cost-effective way and with the most appropriate equipment for the job at hand. This naturally requires good understanding of and confidence in the instrumentation employed. Clients want the most from what they... (read more)
