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.
Aerial Photography vs Orthophotography: What’s the Difference?
Aerial photography is a type of photography in which you capture images that are distant, from “in the air” using drones, satellites, and more.
Best Drones in 2022
If you are looking for the best drones to spend your money on, we’ve put together a list of the best drones and UAVs with their top features.
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.
Best Handheld GPS Receivers
Whether you’re hiking, geocaching, fishing, snowmobiling, or hunting, we are here to guide you through some of the best handheld GPS today.
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.
