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)

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)

Kansas Lidar Elevation Survey

AeroMetric, USA, has been awarded a contract to provide the State of Kansas with Lidar elevation data covering 9,720 square miles in the eastern part of the State. This is an area including 11 counties, the Missouri river and Kansas City. Funded by state and county agencies, this project is a key component of the Kansas Geographic Information System Partnership initiative which aims at developing a robust geospatial infrastructure to enhance the safety, economy, environment and quality of life in Kansas. This project augments AeroMetric's extensive state mapping experience, which includes major recent projects in Alaska, Minnesota, North... (read more)

Maputo Base Map Survey

Getmapping in partnership with Geosense, ESRI South Africa and Precision Surveys has recently completed a 500sq km aerial survey of Maputo and its environs including the islands Xefina and Inhaca. The survey was commissioned by the Municipal Council of Maputo to create a new base map for the city's new geographic and management information systems. Maputo is a port on the Indian Ocean, the capital and largest city of Mozambique. A thriving manufacturing and export centre, Maputo's infrastructure is under considerable pressure from rapid population growth fuelled by internal migration from traditional rural farming areas. With existing geographic maps and... (read more)

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)
