EuroSAT dataset is based on Sentinel-2 satellite images covering 13 spectral bands and consisting of 10 classes with 27000 labeled and geo-referenced samples. Now that we have our images we need to label them for classification. In actual fact, it is pretty rare to have perfectly balanced data in classification tasks. An example of an imbalanced classification problem where a class label is required and both classes are equally important is the detection of oil spills or slicks in satellite images. The aim is to predict this classification, given the multi-spectral values. On a side note, USGS Earth Explorer now warehouses Sentinel-2 data. The GLS2005 data set is a collection of 9500 orthorectified leaf-on medium-resolution satellite images collected between 2004 and 2007 and covering the Earth's land masses. Introduction to Hyperspectral Images(HSI) In Remote Sensing, Hyperspectral remote sensors are widely used for monitoring the earth’s surface with the high spectral resolution.Generally, the HSI contains more than three bands compared to conventional RGB Images. The remaining bands are primarily intended to identify and monitor land use and land cover classes.

It is implemented in Python using the Keras and TensorFlow deep learning libraries and runs on a Linux server with an NVIDIA Titan X graphics card. Confusion matrix of a fine-tuned ResNet-50 CNN on the proposed EuroSAT satellite images dataset. What is driving some of this is now large image repositories, such as ImageNet, can be used to train image classification algorithms such as CNNs along with large and growing satellite image repositories. * In the Geospatial applications, Image Classification works well for the standard formats such as tile service, allowing sizing up entire imagery data set into standard slices, or tiles, which are further classified with binary or class options.For example, does this tile include a building or not? List of aerial and satellite imagery datasets with annotations for computer vision and deep learning. Data Set Information: The database consists of the multi-spectral values of pixels in 3x3 neighbourhoods in a satellite image, and the classification associated with the central pixel in each neighbourhood. The dataset is divided into five training batches and one test batch, each containing 10,000 images. Learn how to create satellite sample patches directly from Google's Earth Engine … Each image may contain one or multiple targets in different weather and illumination conditions. This is the highest resolution earth observation satellite imagery. The Resnet50 model achieves a promising result than other models on three different dataset SAT4, SAT6 and UC Merced Land. Works with Python 3 and above. 1000 Images, text Classification 2009 F. Tanner et al. Satellite imagery analysis, including automated pattern recognition in urban settings, is one area of focus in deep learning. Satellite data changes the game because it allows us to gather new information that is not readily available to businesses. In order to improve the chance of getting valuable image patches, they have selected satellite images with a low cloud level. For example, Sentinel-2 products include multispectral mosaic data (GeoPackage or MapCache SQLite files or GeoTIFFs (RGB or RGB/NIR). In recent years, satellite image datasets have become available to anyone with a computer and an internet connection. Earth Engine's public data archive includes more than forty years of historical imagery and scientific datasets, updated and expanded daily. For this project, I utilized images from the SpaceNet dataset taken by Digital Globe’s WorldView-3 satellite. Many imbalanced classification tasks require a skillful model that predicts a crisp class label, where both classes are equally important. The domain d is measured on countries. What this project is about, 2. CIFAR-10: A large image dataset of 60,000 32×32 colour images split into 10 classes.
