Protocols

• CEOS: QA4EO-WGCV-IVO-CLP-002 Protocol for the CEOS WGCV Comparison of techniques/instruments used for surface IR radiance/brightness temperature measurements

  The overarching objective of this comparison is “To establish the “degree of equivalence” between surface based IR Cal/Val measurements made in support of satellite observations of the Earths surface temperature and to establish their traceability to SI units through the participation of national standards laboratories”.

• CEOS: QA4EO-WGCV-IVO-CLP-008 Protocol for the CEOS WGCV pilot Comparison of techniques/instruments used for vicarious calibration of land surface imaging through a ground reference standard test site

  Objective is to identify and evaluate any biases between different participants in assigning a “radiometric value” to a test site.

Guidelines

• ASPRS: Aerial Camera In Situ Metric Calibration Guidelines (Draft)

  These guidelines are intended to serve as guidance for the airborne in situ metric calibration of vertically oriented digital and film-based frame type cameras.

• CEOS: QA4EO-WGCV-IVO-CLP-003 A procedure for establishing a "land-based" reference standard test-site

  This document describes the procedure that should be followed to establish a new “reference test site” for the calibration and validation of radiometric gain of a land surface imager.

• CEOS: QA4EO-WGCV-IVO-CLP-004 A best practice guide to land "test-site" characterization

  This is a “Best practice guide” to the characterisation of the properties of a land-based test-site, which impact on its radiometric use with optical remote sensors.

Standards

• ISO/TS 19159-1:2014 Calibration and validation of remote sensing imagery sensors and data - Part 1: Optical sensors

  ISO/TS 19159-1:2014 defines the calibration and validation of airborne and spaceborne remote sensing imagery sensors.
