Note that the vector data is, understandably so, available only for training datasets. The CSV provides the coordinates of the vertices of the building footprint (polygons) as latitude and longitude in the same map projection as the images, and the GeoJSON provides this same information in pixel coordinates relative to the image.ĬSV files are present in “ summaryData” directory and GeoJSON files are present in “ geojson/buildings” for buildings’ labels or inside “ geojson/spacenetroads” for roads’ labels. Vector data, such as building footprints, are provided in SpaceNet dataset in both CSV and GeoJSON formats. Near Infrared (NIR) bands 1 & 2 can be used to perform NIR spectroscopy, whose applications include investigating plant health, soil conditions and atmospheric analysis. ![]() The significance of this channel is that Chlorophyll is transparent to wavelengths > 700nm, leading to nicer application for vegetative analysis. The Red-Edge (705–745nm) provides wavelengths of light just beyond the Red wavelengths. Separating Yellow and also including Coastal Blue bands allow for novel feature extraction such as vegetative analysis by providing “yellower” and “bluer” information of objects. The data generated from each satellite varies in terms of features such as resolution, geolocational accuracy etc.Īpplication areas for different spectral bands (NOTE: SpaceNet dataset doesn’t include SWIR and CAVIS bands)Īs you can see in the above image, the RGB bands in 8-band images do not include Yellow band. The satellites include QuickBird, GeoEye-1 and the WorldView Series (WorldView-1, WorldView-2, WorldView-3 and WorldView-4). ![]() Digital Globe owns a “constellation” of satellites that capture high quality remote sensing imagery. The satellite imagery is provided by Digital Globe, an American vendor of space imagery and geospatial content. In order to better understand the dataset, it is helpful to know from where the data is sourced. CosmiQ Works, Radiant Solutions and NVIDIA have partnered to release the SpaceNet data set to the public in order to foster innovation in the field of computer vision with algorithms that can automatically extract geometric features such as roads, buildings etc. This imagery is accompanied by labelled information that can be used to train machine learning models.
