However, many others are free of charge and are essential to extract and processing the data. Many of these digital images come from private satellites and are expensive. In order to obtain such data, it is important to examine in detail the information in satellite imagery. In addition, some of them have an extraordinary resolution that enables to obtain reliable satellite data and complete evaluations with a single image. That information is essential for the business decision-making processes. For instance, it can help to analyse the condition of roads and buildings for monitoring construction sites and urban development planning. Nowadays, there is more and more relevant information that we can receive from satellites. The development of satellite technologies has increased at a remarkable pace over the past few years. Extracting accurate, reliable, and continuous information through high-quality observation programs is a key feature for understanding the environment and improving its management and conservation. Additionally, they provide solutions for vegetation levels assessment and management, detection of harmful algal blooms in the ocean, or mapping of the global flow of oil and monitoring potential oil spills.Įarth observation from space has been one of the greatest challenges for scientists since the beginning of the 20th century. Some of the utilities that satellite imagery can provide through imagery are the monitoring of the consequences of climate change, such as wildfire or floods, droughts and land use tracking.
