I also had a learning rate policy step which dropped the learning rate at around 0.2 of the initial rate for every 30 epochs. The colors in an image will depend on what kind of light the satellite instrument measured. SSEC develops and utilizes instrumentation, algorithms, satellite ground and satellite archive systems to study the Earth and other planetary atmospheres. The sliding window steps are shown below: Oversampling standing water and waterway together was a good idea since it helped to reduce the amount of class confusion between the two, with reduced artifacts (particularly for standing water predictions). The Farming by Satellite Prize 2020, promoting the use of satellite technologies in agriculture, was awarded on Monday 30th November at the virtual awards ceremony. For live weather imagery, it uses NOAA GOES (Geostationary Operational Environmental Satellite) which is administered by NASA. However, in the real world, clouds and competition for satellite time are significant obstacles. U-NET training & ensembling with a variety of models that permuted bands and scales. I first tried bounding boxes, then polygon approximation, and then polygon with erosion in OpenCV. The public and private LB score for this class seemed competitive relative to other teams who may have used deep learning methods. For oversampled classes only 5% random patch were used. The SDSN is a leading nongovernmental … I used three desktops for this contest. Install the Alexa Browser Extension to get free competitive intelligence about millions of websites while you browse the web. Her winning project: a tool to predict crop harvests. The remaining (20%) was on developing the post and pre-processing flows. Various widths (256x256, 288x288, etc.) Moreover, the NDWI mask (generated as part of waterways) could be overlapped with the raw standing water predictions, and very close broken segments could be merged (convexHull) to form a complete contour that may touch the boundary of the image. One swarm measured 60 x 40 kilometres wide in the country’s northeast area, Intergovernmental Authority on Development (IGAD) said in a press release. Most importantly, have fun during the competitions — it won’t even feel like work when you are having fun (!) I made tweaks to the original architecture with batch-normalization on the downstream paths + dropout on the post-merge paths, and all activation layers switched to Exponential Linear Unit (ELU). Originally published at blog.kaggle.com on April 26, 2017. The challenge was organized by the Defence Science and Technology Laboratory (Dstl), an Executive Agency of the United Kingdom’s Ministry of Defence on Kaggle platform. Many features (such as histogram of oriented gradient, local binary pattern, scale-invariant feature transform, etc.) False-color images incorporate infrared light and may take on unexpected colors. competition keras kaggle-competition segmentation satellite-imagery image-segmentation Updated Jun 9, 2018; Python; doersino / aerialbot Star 157 Code Issues Pull requests A simple yet highly configurable bot that tweets geotagged aerial imagery of a random location in the world. Post-processing on roads, standing water versus waterways, and small versus large vehicles. clock-data recovery, locked loops, high-speed I/O, etc. Index methods for waterways — namely a combination of Non-Differential Water Index (NDWI) and Canopy Chlorophyl Content Index (CCCI). Focuses on the key global Commercial Satellite Imagery manufacturers, to define, describe and analyze the sales volume, value, market share, market competition landscape, SWOT analysis and development plans in next few years. The competition task was to create a 50 drone New Year animation with a maximum length of 5 minutes using Blender animation software. Standing water 9. As a result this solution could have achieved an overall private LB score of 0.50434 (over 0.5 — yay!) All the Best As described earlier, oversampling both standing water and waterways helps to dissolve waterway artifacts in standing water UNET predictions, but there was still a lot of waterway-like remnants, as shown below in raw ensembled standing water predictions: EXAMPLES OF MISCLASSIFIED POLYGONS IN STANDING WATER. Thus most of the foreign competition in the satellite remote sensing market is from imagery providers operating satellites built with substantial governmental funding, and in many cases built by domestic firms. Data will be generated through a constellation of … We also aim to spotlight various federal government employees and interview key government executives whose impact resonates beyond their agency. A satellite carrying a camera that is so powerful it can capture an image of virtually any object on Earth with crystal-clear resolution is now offering its services to the public. description evaluation prizes timeline data-processing-tutorial. Live imagery is updated every 10 minutes from NOAA GOES and JMA Himawari-8 geostationary satellites. "This particular challenge is difficult because many circular features are not going to be perfectly circular nor similar in size," said Jack Brandy, geospatial intelligence capabilities integration officer at NGA. All the collected imagery from above-mentioned satellites is available in Airbus satellite imagery catalog. Then I came across Kaggle’s State Farm Distracted Driver contest, which was a perfect fit. During the day, I design high-speed circuits at a semiconductor startup — e.g. Moreover, data science is an ever evolving field. Large vehicles 10. The first two were used for all the training/inferencing of all classes, while the last one (#3) was only run on crops. One day for preprocessing, one day to train and predict, and another day to predict vehicles and generate submission. As mentioned earlier, for vehicles I trained and predicted only on patches/windows with roads and/or buildings — this helped to cut down the amount of images needed for training, and allowed for significant oversampling of vehicle patches. For example, suppose there are N polygon labels for building footprints that are considered ground truth and suppose there are M proposed polygons by an entry in the SpaceNet competition. More details here! In summary my solution is based on the following: I performed registration of A and M images, and used sliding window at various scales. As part of the Circle Finder challenge NGA is looking for novel automated approaches to help detect, delineate and describe circular shaped features using satellite images. It also uses data from Japan’s and EU’s satellites. He holds a Bachelor’s degree in Electrical and Computer Engineering from Cornell University. You can unsubscribe at any time.

However, for this particular competition, having >= 2 GPU systems will definitely help due to the sheer number of classes and models involved. To understand the structure of Commercial Satellite Imagery market by identifying its various sub segments. Contact us; Advertise with us; Shopping. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imagery and aerial photography can both give you a clear image of the planet Earth, from above. SAR image of China's Jiuquan satellite launch center. I’d like information about a particular satellite mission! The National Geospatial-Intelligence Agency (NGA) has offered a $50,000 prize pool for novel approaches that employ artificial intelligence to detect circular-shaped elements in satellite images. I would have added some ensembling to crops, added heat-map based averaging (and increase the test overlap windows at some expense of runtime), dilated structures training mask (which helped structure scoring for some competitors), and removed most of the expensive rare scale (320x320, for example) ensembling on tracks. Automating feature labeling will not only help Dstl make smart decisions more quickly around the defense and security of the UK, but also bring innovation to computer vision methodologies applied to satellite imagery. In this interview, first place winner Kyle Lee gives a detailed overview of his approach in this image segmentation competition. Over the course of the competition, I definitely achieved this goal since this competition was extra fun — viewing pictures of natural scenery is therapeutic and kept me motivated everyday to improve my methodology. Satellite images have reported an “extremely dangerous increase” in locust swarm activity in Kenya in the past week. It has enabled us to better … My understanding is that most competitors had either weak public or private scores with standing water and vehicles, which I spent extra effort to deal with in terms of pre- and post-processing. I believe stabilizing these two (actually three) classes — standing water, large and small vehicles made a large impact on my final score relative to other top competitors. Sorted by submission deadline. I would also have fixed the contour submission issue on crops had I caught that earlier. In fact, this field wasn’t even on the radar a decade ago — so be sure to keep to date on the architectural improvements year-by-year. To deal with this, I trained additional networks merging both small+large vehicles, and took the union of this network with large vehicle only network ensemble. By MISSY FREDERICK Space News Staff Writer posted: 24 April 2006 12:07 pm ET For small vehicles, it was basically just to take the average ensemble of small vehicle predictions, and remove whichever contours overlapped with large vehicles and/or over the area threshold. List of machine learning competitions for satellite imagery and remote sensing. Well for land use land cover 13-15 zoom level is sufficient. Capella Space Capella Space is now capable of producing high resolution radar images of the Earth’s . March 18, 2015 | by European Space Imaging. All other classes were using the correct shapely versions of the submission script. Welcome to Alexa's Site Overview. He has been involved in data science and deep learning competitions since early 2016 out of his personal interest for automation and machine learning. Furthermore, since the challenge tasks will involve "in the wild" forms of classic computer vision problems, these datasets have the potential to become valuable testbeds for the design of robust vision algorithms, beyond the area of remote sensing. Knowledge accumulated from vision/deep learning related home projects and other statistical learning competitions has also helped me in this effort. As a training set, they provided 25 high-resolution satellite images representing 1 km2areas. October 1, 2020 In terms of cross validation, I used a random patch split of 10–20% across images (depending on class, the rarer the larger). The UNET segmentation network from the “Ultrasonic Nerve Segmentation” competitions and other past segmentation competitions was widely used in my approach, since it is the most easily scalable/sizeable fully convolutional network (FCN) architecture for this purpose. Internet Mapping Portal Competition Benefits Satellite Imagery Businesses As companies with Internet mapping portals such as Yahoo and Google struggle to … Tracks 5. True-color images use visible light—red, green and blue wavelengths—so the colors are similar to what a person would see from space. As far as band usage is concerned, I mostly used panchromatic RGB + M-band and some of the SWIR (A) bands. The primary goal of this challenge is accurate semantic segmentation of different … Having more systems helps in terms of creating experiments and ensemble permutations, but it’s not absolutely necessary if you have a strong flow or network. The overhead satellite images show buildings before and after a natural disaster and have annotated polygons and damage scores for each building. My guess is that my vehicle and standing water scores (combined) were the ones that made a difference in this competition, since the other top competitors had either weak vehicle scores or weak standing water scores. First, enter in your area of interest. Our approach is based on an adaptation of fully convolutional neural network for multispectral data processing. Satellite Image Analysis Reference Guide Datasets. Finally, here is my CV-public-private split per class.

This post-processing resolved class confusion between standing water and waterways, cleaned up artifacts on the roads, and gave some additional points to the large vehicle score. Google satellite downloader is one of them it will facilitate you to download images on several zoom level. Complex Imagery and Map Data Projects Completed at Once; Impossible Ones Take Just a Bit Longer. Credit: Capella Space. Yesterday (January 7 th at 10:59 a.m. and 11:02 a.m. EST), two of Maxar Technologies’ high-resolution satellites collected new imagery of Washington D.C., including the U.S. Capitol and surrounding area. The task was to locate 10 different types of objects: 1. No augmentation with ensembling was performed on validation or test data. This image of Palm Jumeirah in Dubai was captured by Capella’s Sequoia radar satellite. As I mentioned earlier I participated in one of the earliest segmentation challenges on Kaggle — the “Ultrasonic Nerve Segmentation”. newcomers earth observation-guide. Founded 2016. Thanks for subscribing! For this competition, the number of true positives and false positives are aggregated over all of the test imagery and the F1 score is computed from the aggregated counts. Title: Satellite Imagery Feature Detection using Deep Convolutional Neural Network: A Kaggle Competition. The key competition that introduced me to the tools and techniques needed to win was Kaggle’s “Ultrasound Nerve Segmentation” that ended in August 2016 (and I saw many familiar names from that competition in this one too!). Secondly, many vehicles were very hard to distinguish between large and small classes both in terms of visibility (blurred) and mask areas. The National Geospatial-Intelligence Agency is offering $50,000 in prizes for artificial intelligence solutions designed to help detect circles in satellite images.

(hereinafter referred to as the "Client(s)"). Starlinks currently orbit at heights reaching 547 km. Firstly, I noticed — both on the training data and just simply common sense — is that vehicles are almost always located on or near roads, and near buildings. The agency cited fuel storage tanks, agricultural irrigation areas, traffic circles and fountains as examples of circular features. The asterisk (*) for private LB score on crops indicate a bug with OpenCV’s findContours, that if I had used the correct WKT generating script for that class I would have had a crop private LB score of 0.8344 instead of 0.7089. Keras with Theano backend + OpenCV / Rasterio / Shapely for polygon manipulation. Images , animations , and Google Earth files from the Hurricane Satellite (HURSAT) for hurricanes, typhoons, and tropical cyclones from 1983 through 2009. I ended up with a intersection of NDWI and CCCI masks (with boundary contact checking to filter out standing water / building artifacts) rather than using deep learning approaches, thus freeing up training resources for other classes. Additionally, both vehicle masks were cleaned by negating their masks with buildings, trees, and other classes. January 6, 2021 Southwestern Athletic Conference (SWAC) Teams Return to Athletic Competition Enabled by Draganfly Technologies. Top Tier Worldwide Data European Space Agency Registration Required.

Optimization wise I used the Jaccard loss directly with Adam as optimizer (I did not get much improvement from NAdam). A lot of experience training neural networks — particularly segmentation networks, working with multi-spectral images, and improving on traditional computer vision processing skills. I then performed area filtering of this union (nominally at 200pixel²) to extract large vehicles only. Our vast archive includes imagery from all leading providers, such as DigitalGlobe, Airbus, and Satrec Imaging. Previously known as Flash Earth. I joined Kaggle after first trying to improve my 3-layer shallow networks on Lasagne for single-board computer (SBCs, e.g. Acquisitions in Satellite Imagery Machine Learning Companies. Having said that, I am still a beginner in many areas in data science — and still learning, of course. Slingshot Aerospace. This paper describes our approach to the DSTL Satellite Imagery Feature Detection challenge run by Kaggle. Explore worldwide satellite imagery and 3D buildings and terrain for hundreds of cities. Ensembling involved the use of mask arithmetic averaging (most classes), unions (only on standing water and large vehicles), intersections (only on waterways using NDWI and CCCI).
