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;...

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)

Ordnance Survey Exhibition

Ordnance Survey, UK, has joined forces with Southampton City Council to celebrate over 160 years of history between the map makers and the city with an exhibition at the Maritime Museum. Ordnance Survey In Southampton: Mapping Great Britain Since 1791 celebrates a long association between the national mapping agency and the city of Southampton and the Ordnance Survey’s recent move to a new head office at Adanac Park, near the M271.     As well as a number of artifacts illustrating past surveying and cartographic techniques there is a mine of information on Ordnance Survey, past and present. Take 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...

Indian Town Expansion Survey

The Barbari (India) civic body has decided to outsource surveying and mapping for new areas added to its limits where 54 town planning schemes are lined up. After the merger of new areas, AMC's limits now extend over 466 sq km, up from 192 sq km. Initial mapping involves field survey of areas based on data that the city survey office already has acquired, marking open lands, green patches and existing structures spread over an estimated 8,190 hectares in the areas for which 54 town planning schemes will be prepared in the next three years. According to Bhupendra Patel, chairman... (read more)

Product Survey GNSS Receivers

In contrast to that of 2005, this product survey on GNSS receivers does not reveal any remarkable technological break-throughs. Manufacturers are increasingly producing systems able to receive Navstar, Glonass and even Galileo signals. This year we have replaced the term GPS (Global Positioning System) by GNSS, because GNSS (Global Navigation Satellite System) better describes the significance and use of these receivers. From providing only position (where am I?) the receivers have evolved into real navigation systems (how do I get to get where I want to go?) The receivers listed here represent the high-end segment of a pyramid-shaped market. Like... (read more)

Product Survey on DPW

The capabilities of the software systems listed differ a lot, and end-user scope and intended types of applications are the decisive elements in their choice. Although many photogrammetric projects are still flown with analogue cameras, as soon as the film is developed it is scanned to transform grey and colour tones into pixels, so enabling a complete digital workflow. In our previous product survey (March 2005) we were able to conclude that the photogrammetric workflow had definitely become digital, enabling automation of such tasks as aerotriangulation, creation of Digital Elevation Models (DEM) and production of orthoimages. As a result, DPWs... (read more)
