Title: | VGI QUALITY CONTROL | Authors: | Fonte, C. C. Bastin, L. Foody, G. Kellenberger, T. Kerle, N. Mooney, P. Olteanu-Raimond, A.-M. See, L. |
Keywords: | Volunteered Geographic Information (VGI); Data Quality; National Mapping Agency (NMA); Crowd-sourcing; Citizen Science | Issue Date: | 2015 | Publisher: | Conference Proceedings | Project: | COST Action TD1202 ‘Mapping and the Citizen Sensor’. http://www.citizensensor-cost.eu. | Serial title, monograph or event: | ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences | Volume: | II-3/W5 | Abstract: | This paper presents a framework for considering quality control of volunteered geographic information (VGI). Different issues need to be considered during the conception, acquisition and post-acquisition phases of VGI creation. This includes items such as collecting metadata on the volunteer, providing suitable training, giving corrective feedback during the mapping process and use of control data, among others. Two examples of VGI data collection are then considered with respect to this quality control framework, i.e. VGI data collection by National Mapping Agencies and by the most recent Geo-Wiki tool, a game called Cropland Capture. Although good practices are beginning to emerge, there is still the need for the development and sharing of best practice, especially if VGI is to be integrated with authoritative map products or used for calibration and/or validation of land cover in the future. | URI: | https://hdl.handle.net/10316/109174 | ISSN: | 2194-9050 | DOI: | 10.5194/isprsannals-II-3-W5-317-2015 | Rights: | openAccess |
