[Termes IGN] surveillance de la végétationRésumé : (Auteur) Three-dimensional high throughput plant phenotyping techniques provide an opportunity to measure plant organ-level traits which can be highly useful to plant breeders. The number and locations of cotton bolls, which are the fruit of cotton plants and an important component of fiber yield, are arguably among the most important phenotypic traits but are complex to quantify manually. Hence, there is a need for effective and efficient cotton boll phenotyping solutions to support breeding research and monitor the crop yield leading to better production management systems. We developed a novel methodology for 3D cotton boll mapping within a plot in situ. Point clouds were reconstructed from multi-view images using the structure from motion algorithm. The method used a region-based classification algorithm that successfully accounted for noise due to sunlight. The developed density-based clustering method could estimate boll counts for this situation, in which bolls were in direct contact with other bolls. By applying the method to point clouds from 30 plots of cotton plants, boll counts, boll volume and position data were derived. The average accuracy of boll counting was up to 90% and the R2 values between fiber yield and boll number, as well as fiber yield and boll volume were 0.87 and 0.66, respectively. The 3D boll spatial distribution could also be analyzed using this method. This method, which was low-cost and provided improved site-specific data on cotton bolls, can also be applied to other plant/fruit mapping analysis after some modification.

[Termes IGN] organisation du travailRésumé : (Auteur) Spatial Data Infrastructure (SDI) is a framework of policies, standards and technology that enables data providers to publish, and users to access and integrate, distributed heterogeneous geospatial information. Despite recognition of the important role played by SDI governance, its scope and overall role in enabling an SDI remain unclear. Each SDI initiative must thus independently tackle the same set of challenges. This results in duplicative and inconsistent approaches that hamper prospects for attaining interoperability, inter-SDI leveraging and reuse of governance resources.

[Termes IGN] utilisation du solRésumé : (Auteur) In 1999, the Ministry of Land and Resources (MLR) of China launched the National Land Use Change Program especially to monitor the scale and distribution of urban expansion and the decrease in cultivated land through remote sensing technology. This Program has been carried out annually and continuously for seven years since then and played an important role in the policy-making of MLR about land management and planning. This paper gives an overview about this Program and discusses several research issues. First, the remote sensing data sources and other ancillary data used in this Program are presented. The approaches for image preprocessing, i.e. radiometric normalization, image geometric rectification and image fusion are then introduced with an emphasis on the algorithm development for image registration. Second, land use change detection technique is the most critical and complex aspect of the Program. The methodologies for change detection using either bi-temporal image pair or one existing land use map and one remotely sensed image are detailed. Third, since the data of land use changes derived from remote sensing will be operationally used for local and central government, field validation and accuracy assessment are crucial to ensure the reliability of change detection results. The strategy of field work and the resulting accuracy evaluations is presented. The land use and change information derived from remotely sensed data has wide applications for land management, including land use database updating, verification of land use planning and monitoring of national high-tech parks. Last, suggestions on how to make full use of the images and change detection result, to improve the consistency of land use classification and to develop change detection algorithms for diverse and complex remote sensing data are given.

[Termes IGN] système d'information géographiqueRésumé : (Editeur) A system has been developed for managing agricultural grants in Ireland. It extends Oracle Spatial databases by adding web-based spatial information management functionality and does not require the use of complex proprietary application specific software to differenciate itself from traditional GIS. The system serves 125 000 farmers for a total of 700 000 fields parcels. The authors show the potentialities of the technology as developed for the Irish Department of Agriculture.
