Earth observation is a fundamental tool for monitoring the evolution of land use in specific areas interest. Observing and precisely defining change, this context, requires both time-series data pixel-wise segmentations. To that end, we propose DynamicEarthNet dataset consists daily, multi-spectral satellite observations 75 selected interest distributed over globe with imagery from Planet Labs. These are paired monthly semantic segmentation labels 7 cover (LULC) classes. first provides...

Few experiments have been performed to investigate near-field egocentric distance estimation in an Immersive Virtual Environment (IVE) as compared the Real World (RW). This article investigates IVEs and RW conditions using physical reach verbal report measures, by apparatus similar that used Bingham Pagano [1998]. Analysis of our experiment shows compression both IVE participants' perceptual judgments targets. is consistent with previous research action space Augmented Reality (AR)....

SUMMARY It is well known that the axial dipole part of Earth’s magnetic field reverses polarity, so North Pole becomes South and vice versa. The timing reversals documented for past 160 Myr, but conditions lead to a reversal are still not understood. if there reliable ‘precursors’ (events indicate upcoming) or what they might be. We investigate machine learning (ML) techniques can reliably identify precursors based on time-series field. basic idea train classifier using segments dipole. This...

Accurate identification of crop phenology timing is crucial for agriculture. While remote sensing tracks vegetation changes, linking these to ground-measured growth stages remains challenging. Existing methods offer broad overviews but fail capture detailed phenological which can be partially related the temporal resolution datasets used. The availability higher-frequency observations, obtained by combining sensors and gap-filling, offers possibility more subtle changes in development, some...

Abstract. Benefiting from the high cadence and spatial resolution of new generation Earth observation satellites, remote sensing technology is allowing us to derive more valuable information for agricultural sector. Crop classification one fundamental derivatives data researchers used food security, crop monitoring, economic assessment. The robustness a model variations in environmental management conditions due time location crucial requirements. To achieve this, we developed novel...

This work proposes a deep learning based method to de-speckle SAR images that does not require noise-free reference data. Instead, our exploits the redundancy between of same area at different times train residual convolutional neural network in regression framework predict speckle-free images. Moreover, thanks end-to-end training network, approach explicit parameter tuning. Experiments show relevance on Sentinel 1 acquired over volcanic areas. The is shown compete well with well-known...

Abstract Shifting focus In the classic history of landscape architecture, Norman Newton's Design on Land, noted Harvard professor implied he was drawn to profession by a series photographs depicting creation Bronx River Parkway, which appeared in official reports and popular magazines 1910s 1920s.1 Newton reproduced two these images his book (figurer). The first photograph portrayed conditions prior parkway, showing denuded river banks lined small frame houses, privies, factories. second...
