How GPS Receivers Work – Trilateration vs Triangulation
Have you ever wondered how your GPS receiver works? They use a technique called trilateration, which measures distances, not angles as in triangulation.

LiDAR
5 Best Free LiDAR Software Tools and Applications
From viewers to desktop applications, these are the best and free LiDAR software tools for visualization, analysis, and conversion.
Remote Sensing Analysis
What is Photogrammetry?
Photogrammetry uses photographs from at least two different vantage points. It obtains depth and perspective because of separate points of observation.
Remote Sensing Types
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.
Image Classification
Spectral Signature Cheatsheet – Spectral Bands in Remote Sensing
Every object has its own unique composition. This is equivalent to it having its own spectral signature. Choose the spectral bands for ideal classification
