Learn Synthetic Aperture Radar (SAR) by Example
Synthetic Aperture Radar (SAR) is an emerging technology in remote sensing with the advantage to see in any weather condition and even at night.
Remote Sensing
Hyperspectral Imaging from Space
Hyperspectral imaging takes a spectrum of light and divides the light into hundreds of narrow spectral bands. For example, Hyperion has 242 bands at 30m GSD.
What is Photogrammetry?
Photogrammetry uses photographs from at least two different vantage points. It obtains depth and perspective because of separate points of observation.
GOES vs POES: A Tale of Two Weather Satellites
GOES and POES are both operational environmental satellites. But they actually share more in common such as their 40+ year legacy in space.
Worldview Satellite by Maxar
DigitalGlobe’s cutting-edge high resolution Worldview satellite carves out ridiculously crisp imagery at 31 cm in 8 spectral bands.
What is Geocaching – A Beginner’s Guide
Geocaching is a treasure hunt style game using a GPS receiver. Geocaches are meaningful places that someone hand-picked to become a hiding spot.
MODIS: Moderate Resolution Imaging Spectroradiometer
Despite popular belief MODIS is a satellite, it’s actually an instrument on-board a satellite. It has 36 bands, 250-1000 meter resolution and 2-day revisits.
The 50 Most Influential Satellites in Remote Sensing
A list of the 50 most iconic satellites put up into space to monitor our planet. We show the uses and types of satellites like weather and GPS satellites.
Landsat 8 Bands and Band Combinations
We list Landsat 8 bands as well as popular band combinations which includes coastal, blue, green, red, NIR, SWIR-1, SWIR-2, cirrus and two thermal bands.
Sentinel 2 Bands and Combinations
Sentinel 2 has a total of 13 bands. Each band is 10, 20 or 60 meters in pixel size. This includes red, green, blue, near infrared and short infrared bands.
