Global understanding of Earth's land surfaces greatly boosted by satellite data

ESA perform land surface monitoring with a range of instruments onboard satellites acquiring optical and radar data. Collections of data from these missions are freely available for research purposes.

New worldwide dataset captures the planet in fine detail

Scientists have developed an open source planetwide dataset of high-resolution Earth observation imagery, thanks to commercial data delivered by ESA’s Third Party Missions (TPM) programme.

Spot Extended Area mode added to ICEYE on-demand portfolio

As an evolution of Spot mode, Spot Extended Area products are now available with the same resolution of Spot data (ground resolution of 1 m) but enabling to cover the area of 225 km2 (15 x 15 km) in a single SAR image.

About SPOT 1

SPOT 1 (Satellite pour l'Observation de la Terre) was a commercial Earth-imaging satellite from CNES (Centre National D’Etudes Spatiales), the French Space Agency. It was launched on 22 February 1986 and ceased operations in November 2003. SPOT 1, 2 and 3 were identical.

*Mission Parameters*
Orbit Height	832 km
Orbit Type	Sun-synchronous
Orbit Inclination	98.7°
Orbit Duration	101 min
Repeat Cycle	26 days

SPOT 1 Objectives

SPOT 1, supplying high-resolution, wide-area optical imagery, was designed to improve the knowledge and management of Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena.

SPOT 1 Instruments

High-Resolution Visible (HRV)

Two identical HRV (High Resolution Visible) imaging instruments on SPOT 1 provided data at 10 metre spatial resolution and were able to operate in two modes Panchromatic mode and 20 metre (Multispectral mode) with a swath of 60 km simultaniously or individually.

The HRV had an oblique viewing capability of 27° on each side of the local vertical.The swath was 117 km² if both sensors were used simultaniously with a 3 km² overlap.
