15 Best Remote Sensing Software
Whether you’re a professional geographer or just a hobbyist, this list of remote sensing software available will help you get the job done.

What is Pansharpening in Remote Sensing
By combining the panchromatic band with multispectral imagery, pansharpening produces images of higher resolution for better visual clarity.
Landsat 9: A Legacy of Earth Observation
In order to continue the Landsat program’s long-standing legacy, NASA and the USGS launched Landsat-9 in September 2021 as the 9th satellite.
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
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.
