The aim is to predict this classification, given the multi-spectral values. We also present a novel metric called Disaster Impact Index (DII) and use it to quantify the impact of two natural disasters - the Hurricane Harvey flood and the Santa Rosa fire. It is important to note that clouds are a huge problem when it comes to satellite images. Users can share a permanent link or download the required free satellite images via the snapshot option selecting the preferred resolution (30 m-10 km), file format (JPEG, KMZ, GeoTiff, PNG), zipping, and clicking the download button. A year ago, Planet Labs launched 150 satellites each the size of a shoe box. When you think of satellite images you might think about Google Maps, which provides you with satellite images that give you a snapshot of the surface of the Earth. As far as we know, FGSD is the largest fine-grained ship recognition dataset in remote sensing fields. The platform is previously known as Earth Viewer and belonged to Keyhole Inc., bought by Google in 2004. GID consists of two parts: a large-scale classification set and a fine land-cover classification set. How to Acquire Large Satellite Image Datasets for Machine Learning Projects. This means that if you zoom in very closely on a quality satellite image, one pixel is going to represent approximately 25 cm of the Earth’s surface. Sentinel Playground, in its turn, contains a satellite imagery mosaic of the globe derived from Sentinel-2, Landsat 8, MODIS, or DEM. This visualization shows the scale of what is going on above our heads, outside the stratosphere. And there are several commercial outfits that offer even better images with more potential uses. .

It comprises 24 pairs of multispectral images taken from the Sentinel-2 satellites between 2015 and 2018. Different image augmentation methods are used to increase diversity in the chosen dataset and create more robust classification. Can choose from 11 species of plants. The imagery on the portal is grouped into several collections (e.g., Proba-V, Spot-vegetation, Sentinel-2, Metor-AVHRR, Envisat-Meris). *By completing the form, I agree to receive commercial information by email from Appsilon. The portal is a large repository for free satellite image data housed and operated by the Department of Geographical Sciences at the University of Maryland, U.S. Multivariate, Text, Domain-Theory . Recently, it has been enriched by Sentinel-1 images to create a multi-modal BigEarthNet benchmark archive (called also as BigEarthNet-MM). The platform has preview and download options with custom download or links to data files in the TIFF format. EuroSAT dataset consists of 27,000 labeled images with 10 different land use and land cover classes. The platform highlights usage examples referring to agriculture, disaster response, satellite imagery, geospatial, etc. It comprises free access satellite imagery mainly within the scope of the Indian continent, with several features applicable for global use (e.g., NDVI global coverage). The app from NASA’s EOSDIS allows interactive browsing of full-resolution satellite imagery available globally, in near real-time (after three hours of retrieval). Search. So if you want to identify people in a lot of images or you need a consistent and precise historical record for research, it is going to be quite expensive for you at the moment. The free data collection originates from multiple sources verified by NOAA. Analysis. The up-to-date images provide information on disaster management (fires, floods) and air quality. This can be crucial in many cases. Unlike most free satellite imagery sources, LandViewer enables instant visualization and analysis of the data you’ve found. So be prepared that your first search for satellite images can be quite time-consuming. Home Objects: A dataset that contains random objects from home, mostly from kitchen, bathroom and living room split into training and test datasets.
