Satellite data by task
Which data suits a task, why, and what Terrascout returns for it, with the agencies’ own sources for every claim.
Satellite data for flood mapping in Australia
Which satellite data maps floods in Australia: radar first because it sees through cloud, optical imagery when it clears, and LiDAR for flood models.
ReadSatellite data for bushfire burn severity mapping in Australia
How burn severity is mapped from satellites: the Normalized Burn Ratio from near and shortwave infrared, before and after the fire, with Sentinel-2 and Landsat.
ReadSatellite data for ground subsidence and deformation (InSAR)
How ground subsidence is measured from space with radar interferometry (InSAR): which data to use, why Sentinel-1 leads, and the limits to know.
ReadSatellite data for vegetation and crop monitoring in Australia
Which satellite data suits vegetation and crop monitoring in Australia: NDVI from Sentinel-2 and Landsat, and DEA Fractional Cover back to 1986.
ReadSatellite data for land use and land cover change in Australia
Which satellite data suits land cover change in Australia: a long, consistent Landsat record, DEA Land Cover from 1988, and Sentinel-2 detail from 2015.
ReadSatellite data for urban heat mapping in Australian cities
Which satellite data maps urban heat in Australian cities: Landsat land surface temperature, ECOSTRESS at 70 m, and why it is not air temperature.
ReadSatellite data for water quality and algal bloom monitoring in Australia
Which satellite data suits water quality and algal blooms in Australia: Sentinel-2 for small waters, Sentinel-3 for large ones, and the limits to know.
ReadSatellite data for coastal erosion and shoreline change in Australia
Which satellite data maps coastal erosion in Australia: a tide-corrected Landsat record, DEA Coastlines every year since 1988, and Sentinel-2 detail.
ReadSatellite data for mine site and rehabilitation monitoring in Australia
Which satellite data suits mine sites in Australia: optical imagery and DEA Fractional Cover for rehabilitation, and radar interferometry for ground movement.
ReadSatellite data for ship and oil spill detection
Which satellite data detects ships and oil spills: Sentinel-1 radar in any weather, AIS on Sentinel-1C and 1D, and how Europe and Australia use it.
