Is RapidEye still in operation?

RapidEye, formerly operated by Planet, is a retired constellation of five satellites, in operation from 2009 to 2020. RapidEye images are approximately 5 meters per pixel resolution. The RapidEye satellite constellation consisted of a single launch of five RapidEye satellites.

What is the resolution of RapidEye satellite images?

RapidEye images are approximately 5 meters per pixel resolution. The RapidEye satellite constellation consisted of a single launch of five RapidEye satellites.

What happened to the RapidEye constellation?

The constellation was deactivated on March 31st, 2020 but Planet still offers data archive. RapidEye is still part of ESA’s Third Party Missions Programme, in which ESA has an agreement with Planet to distribute archive data products from the mission.

What are the Reis sensors on the RapidEye constellation?

The REIS sensors on the RapidEye constellation mean that for the first time, there is a constellation of five Earth imaging satellites that contain identical sensors, which are in the same orbital plane and are calibrated equally to one another.

What is Rapideye ESA archive?

RapidEye ESA archive : RapidEye products that ESA collected over the years. The dataset regularly grows as ESA collects new products

How many satellites are there in the Rapideye?

Together, the five RapidEye satellites are capable of collecting over 4 million square kilometres of 5 m resolution, 5-band colour imagery every day.

What is a REIS satellite?

RapidEye Earth-imaging System (REIS) The REIS sensors on the RapidEye constellation mean that for the first time , there is a constellation of five Earth imaging satellites that contain identical sensors, which are in the same orbital plane and are calibrated equally to one another. An image from one RapidEye satellite is identical in …

Is Rapideye still part of ESA?

at nadir over mid-latitude regions (±84° latitude) RapidEye is still part of ESA’s Third Party Missions Programme, in which ESA has an agreement with Planet to distribute archive data products from the mission.

What is Rapideye Scene and Orthotile?

RapidEye Scene and OrthoTile imagery products are available for download in the form of imagery assets. Multiple asset types are made available for Scene and OrthoTile products, each with differences in radiometric processing, and/or rectification.

What is analytic asset?

Analytic ( analytic) assets are orthorectified, calibrated, multispectral imagery products that have been corrected for sensor artifacts and terrain distortions, and transformed to Top of Atmosphere (at-sensor) radiance. These products are designed for data science and analytic applications which require imagery with accurate geolocation and cartographic projection.

What is basic analytical?

Basic Analytic ( basic_analytic) assets are non-orthorectified, calibrated, multispectral imagery products that have been corrected for sensor artifacts and transformed to Top of Atmosphere (at-sensor) radiance. These products are designed for data science and analytic applications, and for users who wish to geometrically correct the data themselves (leveraging the associated rational polynomial coefficient asset type).

What is surface reflection?

Surface Reflectance ( analytic_sr) assets are orthorectified and radiometrically corrected to ensure consistency across localized atmospheric conditions, and to minimize uncertainty in spectral response across time and location. These products are designed for temporal analysis and monitoring applications, especially in agriculture and forestry sectors.

What is a rectification tiedown?

The rectification tiedown process wherein tie points are identified across the source images and a collection of reference images (ALOS, NAIP, Landsat) and RPCs are generated.

What is Temporal Calibration?

Temporal Calibration: To achieve cross calibration, corrections were applied such that all RapidEye cameras read the same DN (digital number) regardless of when the image has been taken in the mission lifetime.

How big is Rapideye Scene?

RapidEye Scene products range from 75 x 50 square kilometers to 75 x 300 square kilometers. They are represented in the Planet Platform as the REScene item type.
