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)

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...

Geospatial Data Quality Survey

The OGC (MD, USA) Technical Committee's Spatial Data Quality Working Group (WG) has been gathering information and requirements from OGC members for the past year and has now begun primary research on spatial data quality measures. Their survey on spatial data quality went live on Monday 15th October, targeting thousands of geospatial data suppliers and users from around the world. The group seeks to develop an interoperable framework or model for OGC Quality Assurance Web Services that will enable improved access and sharing of high quality geospatial information. To achieve this goal it is necessary to learn what organisations mean... (read more)
