The CubeSat: Small Satellites for Big Ideas
A CubeSat is a miniaturized satellite roughly the size of a Rubik’s cube. They’re small enough to hold in your hand and inexpensive to build.
Remote Sensing
Aerial Photography vs Orthophotography
Aerial photography is a type of photography in which you capture images that are distant, from “in the air” using drones, satellites, and more.
What is a Point Cloud?
A point cloud is a collection of points for storing data in LiDAR systems. Pulses of light represent the millions of points in a point cloud.
Spatial Resolution vs Spectral Resolution
Spatial resolution is how detailed objects are in an image based on pixels. But spectral resolution is the amount of spectral detail in a band.
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.
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.
