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.
Remote Sensing
OBIA – Object-Based Image Analysis (GEOBIA)
Object-based Image Analysis (OBIA) segments an image by grouping pixels together into vector objects. Using these objects, you classify as land cover types.

Image Classification Techniques in Remote Sensing [Infographic]
We look at the digital image classification techniques in remote sensing (such as supervised, unsupervised & object-based) to extracts features of interest.
Spectral Signature Cheatsheet 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
