Quantifying the Uncertainty of Short-Term Vegetation Anomalies Detection Using Eo-Based Coarse-Resolution Vegetation Products
No full textSatellite-based Earth Observation systems archived a variety of vegetation products during the last 50 years, which can reveal regional to global ecosystem dynamics across diverse spatiotemporal scales. The anomaly metrics such as Vegetation Condition Index (VCI) defined by comparing the current vegetation growth condition to historical average status based on long-term EO-based vegetation products were widely used to delineate abnormal vegetation variation exerted by either climatic or anthropogenic factors (e.g., droughts, wildfires). However, currently available long-term vegetation products may differ from each other in terms of sensors (observational platform or spectral bands), bio-physical definitions (e.g., NDVI, EVI, LAI, and VOD), spatiotemporal resolution, as well as the time-spans, which results in inconsistency across these vegetation products. Taking the VCI as an example, this study evaluated the uncertainty of vegetation anomalies detected based on different vegetation products over the middle reach of the Yangtze River by explicitly considering the effect of sensors, biophysical definitions, and time-spans. The preliminary results showed that VCI derived from NDVI products from different sensors (AVHRR vs. MODIS) induced significant inconsistent anomalies over most landscapes. The differences resulting from products with different biophysical definitions (NDVI vs. EVI, LAI, and VOD) are much lower than those from different sensors but still significant over specific areas. As for the time-spans, the 20-year NDVI based VCI presented a considerable reduction in variance over the study area on average compared to VCI calculated based on 5-year NDVI. In summary, caution should be taken when applying EO-based vegetation products for vegetation anomalies mapping, especially for quantitative assessment.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Optical and Laser Remote Sensin

A multistage random sampling technique was used in recruiting respondents to the study. A four-part questionnaire was applied dually, by interviewers and by respondents' self administration, and the data was analyzed using the SPSS software version 17.0.Results: The mean age of respondents was 28.6 ± 6.65 years. The majority (90.3%) of respondents were aware of modern methods of family planning (FP), 76.0% claimed awareness of where to obtain FP services, and 74.9% knew of at least five methods. However, only 30.6% had ever used contraceptives, while only 13.1% were current users. The most frequently used method was the male condom. The commonly perceived barriers accounting for low use of FP methods were fear of perceived side effects (44.0%), ignorance (32.6%), misinformation (25.1%), superstition (22.0%), and culture (20.3%). Some reasons were proffered for respondents' nonuse of modern contraception. Predictors of use of modern contraceptives include the awareness of a place of FP service provision, respondents' approval of the use of contraceptives, higher education status, and being married.Conclusion: Most of the barriers reported appeared preventable and removable and may be responsible for the reported low point prevalence of use of contraceptives. It is recommended that community-based behavioral-change communication programs be instituted, aimed at improving the perceptions of women with respect to bridging knowledge gaps about contraceptive methods and to changing deep-seated negative beliefs related to contraceptive use in Nigeria.Keywords: childbearing age, family planning, fertility desires, perception, knowledge, attitude, benefit

An Observation Capability Metadata Model for EO Sensor Discovery in Sensor Web Enablement Environments
No full textAccurate and fine-grained discovery by diverse Earth observation (EO) sensors ensures a comprehensive response to collaborative observation-required emergency tasks. This discovery remains a challenge in an EO sensor web environment. In this study, we propose an EO sensor observation capability metadata model that reuses and extends the existing sensor observation-related metadata standards to enable the accurate and fine-grained discovery of EO sensors. The proposed model is composed of five sub-modules, namely, ObservationBreadth, ObservationDepth, ObservationFrequency, ObservationQuality and ObservationData. The model is applied to different types of EO sensors and is formalized by the Open Geospatial Consortium Sensor Model Language 1.0. The GeosensorQuery prototype retrieves the qualified EO sensors based on the provided geo-event. An actual application to flood emergency observation in the Yangtze River Basin in China is conducted, and the results indicate that sensor inquiry can accurately achieve fine-grained discovery of qualified EO sensors and obtain enriched observation capability information. In summary, the proposed model enables an efficient encoding system that ensures minimum unification to represent the observation capabilities of EO sensors. The model functions as a foundation for the efficient discovery of EO sensors. In addition, the definition and development of this proposed EO sensor observation capability metadata model is a helpful step in extending the Sensor Model Language (SensorML) 2.0 Profile for the description of the observation capabilities of EO sensors
X-eo: Researching & Designing for Rebellious play
No full textThis reports the graduation project aimed to investigate the occurrence of rebellious play through the X-eo prototype. Rebellious behaviour is often referred to as going against the norm and derives its value from breaking rules. Previous academic research (Gielen & Van Leeuwen, 2013), on the subject, has provided suggestions and techniques to design for this. However, there has been no clear or obvious conclusion as of yet, whether or how rebellious play can be promoted and supported through design.Therefore the brief for this graduation assignment was to “ re-think the bangerik & develop the Bangerik concept and investigate the occurrence of rebellious behaviour during play. As secondary goals; gain insights in designing and researching for rebellious play.”X-eo builds upon the bangerik concept developed during the compulsory DFI master‘s course Interactive Technology Design (ITD) during the 2013/2014 academic year at the faculty of IDE at the Delft University of Technology. Bangerik is an interactive free-flowing game that encourages children to be rebellious in a playful context. It consisted of a wearable worn on the wrist, where the goal of the game to raise their opponent‘s heart rate by scaring them and then steal their lives by tapping their wristband. The project is broken down into four distinct phases: Understand, Ideate, Make and Evaluate. Understand: The “understand“ phase was an immersion into the terminology behind the assignment through literature, an investigation of the original concept, online research of current rebellious concepts and potential technology that could be integrated into the final design to be tested at the end of the project. A definition of rebellious play was created and defined as “Where children can actively challenge what is in place and explore their behavioural boundaries, without having to face or endure any serious or lasting consequences“ This definition accompanied by a model of rebellious play was used to support the start of the ideate phase. The phase concluded with the establishment of research gaps to be investigated during the next stage of the project.Ideate: The “ideate“ phase consisted of 2 iterative design loops to find information that could not be obtained from traditional research methods such as literature reviews and interviews. Ideation focussed on the following research gaps, with prototypes created for each aspect and tested with children at a local school:How to play tag with Bangerik?How to attach something to the body?Where to place the tagging locations on the upper body?How to raise and lower heart rate during play and should this aspect remain in aspect?The video data from the testing sessions were analysed with the following conclusions established: The upper arms and chest are the most suitable tagging locations on the upper body. A garment is best to accommodate the tagging areas on the upper body. The heart rate aspect was a vital element and should be integrated into the final design. Feedback should be integrated into the final design to indicate when the players the heart rate is high and when they have lost a life. Make:The “make“ phase consisted of finalising the concept design and establishing aspects to be examined during the pilot study. Aesthetics, prototype behaviour and functions were finalised.From this point onwards the Bangerik concept evolved into the X-eo concept, a wearable garment tag game that offers the children the opportunities to steal lives from each other by raising other player’s heart rate. The tagging, heart rate and visual behaviour aspects of the concept were selected to be embodied into minimal viable prototypes for the pilot study. Evaluate: The “evaluate“ phase brought a close to the project with the prototypes being tested during the pilot study. The main focus for the pilot was whether the prototype provoked the occurrence of rebellious play behaviour and recommendations for design and research activities with the prototypes in the future. The following sub-questions were operationalised to determine conclusions to the overriding research questions:What strategies do the children implement during gameplay and are they rebellious?Do the children understand the visual feedback when their heart rate is high, when their lives are stolen, when they are out of the game and when their lives are reviving?A hierarchy of rules framework was created, so rebellious tendencies through the children‘s strategies could be identified and classified based on the rules they violated. In conclusion, rebellious behaviour was present during the testing session with all rules within the hierarchy framework being violated, with contextual and societal rules being the most popular. However it cannot be defined whether these behaviours were directly provoked due to the prototype, the context or the motivational state the children were in before completing the test. The hierarchy framework was a useful tool for classifying rebellious play behaviour. The report concludes with an evaluation of the research methodology applied, research & design recommendations and reflections with regards to conducting future research with the X-eo concept and on rebellious play behaviour.Design for Interactio

An AI-Enabled Framework for Real-Time Generation of News Articles Based on Big EO Data for Disaster Reporting
No full textIn the field of journalism, the collection and processing of information from different heterogeneous sources are difficult and time-consuming processes. In the context of the theory of journalism 3.0, where multimedia data can be extracted from different sources on the web, the possibility of creating a tool for the exploitation of Earth observation (EO) data, especially images by professionals belonging to the field of journalism, is explored. With the production of massive volumes of EO image data, the problem of their exploitation and dissemination to the public, specifically, by professionals in the media industry, arises. In particular, the exploitation of satellite image data from existing tools is difficult for professionals who are not familiar with image processing. In this scope, this article presents a new innovative platform that automates some of the journalistic practices. This platform includes several mechanisms allowing users to early detect and receive information about breaking news in real-time, retrieve EO Sentinel-2 images upon request for a certain event, and automatically generate a personalized article according to the writing style of the author. Through this platform, the journalists or editors can also make any modifications to the generated article before publishing. This platform is an added-value tool not only for journalists and the media industry but also for freelancers and article writers who use information extracted from EO data in their articles
