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.
Imagine being able to rewind forty years back in time. For any given place and time. Then, see how much it’s changed. You can through the Landsat Program!
Active sensors illuminates its target and measures that reflected backscatter to the sensor. Passive sensors measure natural energy from the sun.
This list of earth-shattering remote sensing applications will change the way you feel about how this industry is changing our world and the way we think.
Multispectral vs Hyperspectral imagery. Hyperspectral contains hundreds of narrow bands. Multispectral usually consists of only 3 to 10 wider bands.
Object-based Image Analysis (OBIA) segments an image by grouping pixels together into vector objects. Using these objects, you classify as land cover types.
We look at the image classification techniques in remote sensing (supervised, unsupervised & object-based) to extract features of interest.
Every object has its own unique composition. This is equivalent to it having its own spectral signature. Choose the spectral bands for ideal classification
