Evaluation of Mask R-CNN Model for Counting Reproductive Structures of Six Plant Species 1895-2018
Phenology––the timing of life-history events––is a key trait for understanding responses of organisms to climate. The digitization and online mobilization of herbarium specimens is rapidly advancing our understanding of plant phenological response to climate and climatic change. The current common practice of manually harvesting data from individual specimens greatly restricts our ability to scale data collection to entire collections. Recent investigations have demonstrated that machine-learning models can facilitate data collection from herbarium specimens. However, present attempts have focused largely on simplistic binary coding of reproductive phenology (e.g., flowering or not). Here, we use crowd-sourced phenological data of numbers of buds, flowers, and fruits of more than 3000 specimens of six common wildflower species of the eastern United States (Anemone canadensis, A. hepatica, A. quinquefolia, Trillium erectum, T. grandiflorum, and T. undulatum} to train a model using Mask R-CNN to segment and count phenological features. A single global model was able to automate the binary coding of reproductive stage with greater than 90% accuracy. Segmenting and counting features were also successful, but accuracy varied with phenological stage and taxon. Counting buds was significantly more accurate than flowers or fruits. Moreover, botanical experts provided more reliable data than either crowd-sourcers or our Mask R-CNN model, highlighting the importance of high-quality human training data. Finally, we also demonstrated the transferability of our model to automated phenophase detection and counting of the three Trillium species, which have large and conspicuously-shaped reproductive organs. These results highlight the promise of our two-phase crowd-sourcing and machine-learning pipeline to segment and count reproductive features of herbarium specimens, providing high-quality data with which to study responses of plants to ongoing climatic change.

Global Mangrove Watch: Mangrove Habitat Mask
<p>This is the habitat mask used to define the locations where mangroves can be found. It was used during the creation of the Global Mangrove Watch (GMW; <a href="https://www.globalmangrovewatch.org/?map=eyJiYXNlbWFwIjoibGlnaHQiLCJ2aWV3cG9ydCI6eyJsYXRpdHVkZSI6MjAsImxvbmdpdHVkZSI6MCwiem9vbSI6MiwiYmVhcmluZyI6MCwicGl0Y2giOjB9fQ%3D%3D">https://www.globalmangrovewatch.org</a>) extent products. Details of how this layer was originally produced are within Bunting et al., 2018 but it has subsequently been edited with further regions added as the GMW layers have been updated and improved.

Kodaikanal Solar Observatory (KoSO) White-Light Sunspot Regions Masks (1904-2017)
<p>Regular observations at the Kodaikanal Solar Observatory (KoSO) began in 1904 using a white-light telescope with a 10-cm aperture lens and an f/15 light beam. Between 1912 and 1917, the objective lens was changed several times. In 1918, a 15-cm achromatic lens was installed. This new configuration produced a 20.4 cm size image of the Sun in the image plane. Photographic plates were used to capture the image. The same telescope has been used since 1918 up until 2017 to take regular white-light observations of the Sun. This data set provides the sunspot mask in HDF5 format for all the White Light Observations acquired at KoSO. Each HDF5 file contains the sunspot mask for all the observations for that year. The sunspot masks are provided in two different coordinate systems: (i) Full Disk as observed and (ii) Carrington heliographic coordinate, which is transformed from full disk using near point interpolation. Each data set also contains metadata in the form of HDF5 attributes. The Carrington co-ordinate data if full Sun map, hence the near-side of the Sun is the region where values in the mask in non-zero, where as sunspot regions are filled with value 2. </p> <p>A <strong>Python package (KoSOpy), which can be located on <a href="https://github.com/Kodaikanal-Solar-Observatory/kosopy" target="_blank" rel="noopener">GitHub</a>,</strong> is being developed which can be used to navigate through these data sets.</p>

Sentinel-2 Cloud Mask Catalogue
<p><strong>Overview</strong></p> <p>This dataset comprises cloud masks for 513 1022-by-1022 pixel subscenes, at 20m resolution, sampled random from the 2018 Level-1C Sentinel-2 archive. The design of this dataset follows from some observations about cloud masking: (i) performance over an entire product is highly correlated, thus subscenes provide more value per-pixel than full scenes, (ii) current cloud masking datasets often focus on specific regions, or hand-select the products used, which introduces a bias into the dataset that is not representative of the real-world data, (iii) cloud mask performance appears to be highly correlated to surface type and cloud structure, so testing should include analysis of failure modes in relation to these variables.</p> <p>The data was annotated semi-automatically, using the <a href="https://github.com/ESA-PhiLab/iris">IRIS toolkit</a>, which allows users to dynamically train a Random Forest (implemented using <a href="https://github.com/microsoft/LightGBM">LightGBM</a>), speeding up annotations by iteratively improving it's predictions, but preserving the annotator's ability to make final manual changes when needed. This hybrid approach allowed us to process many more masks than would have been possible manually, which we felt was vital in creating a large enough dataset to approximate the statistics of the whole Sentinel-2 archive.</p> <p>In addition to the pixel-wise, 3 class (CLEAR, CLOUD, CLOUD_SHADOW) segmentation masks, we also provide users with binary<br> classification "tags" for each subscene that can be used in testing to determine performance in specific circumstances. These include:</p> <ul> <li><strong>SURFACE TYPE</strong>: <em>11 categories</em></li> <li><strong>CLOUD TYPE</strong>: <em>7 categories</em></li> <li><strong>CLOUD HEIGHT</strong>: <em>low, high</em></li> <li><strong>CLOUD THICKNESS</strong>: <em>thin, thick</em></li> <li><strong>CLOUD EXTENT</strong>: <em>isolated, extended</em></li> </ul> <p> </p> <p>Wherever practical, cloud shadows were also annotated, however this was sometimes not possible due to high-relief terrain, or large ambiguities. In total, 424 were marked with shadows (if present), and 89 have shadows that were not annotatable due to very ambiguous shadow boundaries, or terrain that cast significant shadows. If users wish to train an algorithm specifically for cloud shadow masks, we advise them to remove those 89 images for which shadow was not possible, however, bear in mind that this will systematically reduce the difficulty of the shadow class compared to real-world use, as these contain the most difficult shadow examples.</p> <p>In addition to the 20m sampled subscenes and masks, we also provide users with shapefiles that define the boundary of the mask on the original Sentinel-2 scene. If users wish to retrieve the L1C bands at their original resolutions, they can use these to do so.</p> <p>Please see the README for further details on the dataset structure and more.</p> <p> </p> <p><strong>Contributions & Acknowledgements</strong></p> <p>The data were collected, annotated, checked, formatted and published by Alistair Francis and John Mrziglod.</p> <p>Support and advice was provided by Prof. Jan-Peter Muller and Dr. Panagiotis Sidiropoulos, for which we are grateful.</p> <p>We would like to extend our thanks to Dr. Pierre-Philippe Mathieu and the rest of the team at <em>ESA PhiLab</em>, who provided the environment in which this project was conceived, and continued to give technical support throughout.</p> <p>Finally, we thank the <em>ESA Network of Resources</em> for sponsoring this project by providing ICT resources.</p> <p> </p> <p> </p>

Social Media Mask Dataset
<p>The Social Media Mask Dataset is a dataset made up of Twitter Images intended for the training of Convolutional Neural Networks to detect masks in images and video. In this case, the term masks refer to a device worn on the face intended to reduce the spread of respiratory illness. Due to Twitter's TOS, we cannot directly publish Twitter images. Instead, we publish Tweet keys along with information our script uses to download the target image. The file training.json is our suggested training set while testing.json is our suggested test set. Our script download_dataset.py can be used to download the full dataset with a Twitter developer account. </p>
