Landsat File Naming Convention – Scene Identifiers
The Landsat file name structure gives you the what, where, when and how the data was captured. (ex. LXS PPPRRR YYYYDDD GSIVV)
Remote Sensing
Composite Bands: Black and White to Color Imagery
If you want to display rasters in true color, you will have to combine the red, green & blue bands. The ArcGIS Composite Bands tool creates RGB composites.
What Is Selective Availability in GPS?
When selective availability was enabled, this added 50 meters of error horizontally and 100 meters vertically to GPS signals.
What is Atmospheric Correction in Remote Sensing?
Dark object subtraction, radiative transfer models and atmospheric modelling are common techniques used to for atmosphere correction in remote sensing.
Pleiades Satellite Constellation: Spot the Detail
The agile Pleiades satellite constellation is comprised of Pleiades 1A and 1B. They offer dynamic image acquisition at 50cm panchromatic & 2m multispectral.
Satellite Pour l’Observation de la Terre (SPOT)
SPOT-1 (Satellite Pour l’Observation de la Terre) was a French commercial satellite launched in 1986 initiated by the French Space Agency (CNES).
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.
Landsat Program: 50+ Years Archive of Earth
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!
Passive vs Active Sensors in Remote Sensing
Active sensors illuminates its target and measures that reflected backscatter to the sensor. Passive sensors measure natural energy from the sun.
