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
A Complete Guide to LiDAR: Light Detection and Ranging
How would you like to wave your magic wand and find out how far everything is away from you? No magic wands necessary. This is how LiDAR works.
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.
Types of Remote Sensing
Multispectral vs Hyperspectral Imagery Explained
Multispectral vs Hyperspectral imagery. Hyperspectral contains hundreds of narrow bands. Multispectral usually consists of only 3 to 10 wider bands.
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
