The basics

What is satellite imagery for environmental monitoring?

Satellite imagery for environmental monitoring is the use of Earth observation data, captured by optical, radar (SAR), hyperspectral and thermal sensors in orbit, to measure and track changes in water, air, forests, land and climate over time. It lets governments, NGOs and companies see large or remote areas at once, compare them with archive imagery going back to 1999, and act on evidence instead of estimates.

How it works

Optical and multispectral

True-colour, near-infrared and red-edge bands reveal vegetation health, water colour and land cover.

SAR radar

Active microwave pulses see through cloud, smoke and darkness for all-weather, day and night monitoring.

Hyperspectral and thermal

Hundreds of narrow bands and heat signatures detect pollutants, greenhouse gases and temperature change.

FAQ

Frequently asked questions about satellite imagery for environmental monitoring

What is satellite imagery used for in environmental monitoring?

Satellite imagery is used to track water quality, deforestation, land use change, air pollution, carbon emissions, biodiversity loss and natural disasters such as floods and landslides. Comparing images over time shows exactly what changed, where and by how much.

Which satellite sensors are best for environmental monitoring?

Multispectral optical imagery suits vegetation and land cover, hyperspectral imagery (400 to 2500 nm) detects water quality and pollutants, thermal bands show heat and stress, and SAR radar such as GF-3 or LT-1 works through cloud and at night.

How fast can XRTech deliver satellite imagery?

Archive imagery is typically delivered in 4 to 7 days, DEMs in under 21 days, and emergency imagery within 24 hours, as XRTech did for the 2023 Derna, Libya floods.

How much does satellite imagery for environmental monitoring cost?

Archive imagery starts at USD 5 per km² for 51 to 80 cm resolution (minimum 25 km²) and new tasking starts at USD 8 per km² (minimum 100 km²). 30 cm imagery costs USD 20 per km² from archive and USD 30 per km² for tasking.

What is the difference between archive and tasking imagery?

Archive imagery has already been captured, with data going back to 1999, so it is faster and cheaper. Tasking schedules a satellite to capture your area on your dates, which is best for current conditions or regular monitoring.

Can satellites monitor the environment through clouds?

Yes. Synthetic Aperture Radar (SAR) satellites send microwave pulses that pass through cloud, smoke and darkness, so floods and oil spills can be mapped day and night in any weather.

What file formats does XRTech deliver?

XRTech delivers GeoTIFF, IMG, SHP and DWG files in WGS84, UTM or custom projections, through secure cloud delivery or physical HDD, ready for GIS, CAD and modelling software.
