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
15 LiDAR Uses and Applications
We reveal 15 LiDAR uses and applications. LiDAR isn’t a new technology, but it’s been growing so much lately that even your smartphone has it
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
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
