What are the 5 types of satellite images?
Watch What are the 5 types of satellite images? When working with satellite imagery, you can categorize them into various types based on the data they capture and the purpose they serve. Here are five common types of satellite images: 1. Visible Light Images: These images capture the visible portion of the electromagnetic spectrum, including […]
What is EO used for?
Watch Earth observation refers to the collection of information about our planet’s physical, chemical, and biological systems using various technologies, such as satellites, aircraft, drones, and ground-based sensors. This data is gathered for a wide range of purposes and applications, including: 1. Environmental Monitoring: Climate change analysis: Tracking temperature, ice melt, sea level rise, and […]
What are the most common satellite image processing techniques?
Watch What are the most common satellite image processing techniques? Satellite image processing involves various techniques to enhance, analyze, and extract information from satellite imagery. Some of the most common techniques include image enhancement classification change detection image fusion vegetation index calculation geometric correction feature extraction and data visualization These techniques help in tasks like […]
What is open data?
Watch What is open data? Open Data refers to data that organizations provide at no charge, and often with very permissive licensing. An example would be Sentinel-2 data from the European Space Agency, which is multispectral data from their Sentinel-2 satellites provided at no charge from their Copernicus service, as well as from many other […]
What is the difference between an aerial photo and a satellite image?
Watch What is the difference between an aerial photo and a satellite image? Aerial photos and satellite imagery are two types of remote sensing data with different characteristics, advantages, and limitations. Aerial photos are captured at relatively low altitudes and offer higher spatial resolution than satellite imagery, which can provide global coverage and regular revisits […]
What is SAR?
Synthetic Aperture Radar (SAR) is a specific satellite that can capture imagery in all weather conditions, day or night. SAR sends a microwave radar signal to the earth’s surface to detect physical properties.
What are indices?
Indices are calculated using the multispectral bands. These calculations result in the outputs being in the form of an index with values between 0-1. At the same time, the indices provide additional information about the ground surface being imaged.
What Are Multispectral Outputs?
Multispectral outputs are made up of bands within the multispectral spectral ranges. The different options include true colour, false colour urban, false colour infrared, and all optical bands.
What Is Image Output?
Image output is about determining the color or bands and indices you want to obtain in order to gain valuable information about your AOI.
What Is Archive?
Using a console like EarthCache, archive satellite imagery is a purchasing option for imagery that has already been collected. Archive imagery can be passively collected by satellites that constantly collect over the earth.
