Earth Observation Cloud Flag Label

Label a supplied cloud-flag code and source without deriving cloud conditions from imagery.

Description

Label an observation's supplied cloud-flag code and source.

Earth-science records distinguish depth signs, vertical datums, before-present ages, calibration factors and specimen definitions. Apparent porosity can be negative for inconsistent density inputs, and core recovery may exceed the drilled interval. Local labels and supplied transformations do not establish geological interpretation, physical validity or actual observation quality.

Label an observation's supplied cloud-flag code and source.

When to use this tool

Use Earth Observation Cloud Flag Label when you already have observationId, cloudFlagCode, cloudFlagSource and need to label an observation's supplied cloud-flag code and source.

How to use the tool and how it works

  1. Enter observationId, cloudFlagCode, cloudFlagSource. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read label. Use the output convention below.

Require observationId, cloudFlagCode and cloudFlagSource nonempty; quote the code and append its source.1

Limitations and assumptions

  • No cloud mask is evaluated, observation screened or atmospheric validity established.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Use verified survey, sample, sensor and timescale records with consistent units and reference frames. Apply the complete geological, hydrological or physical model when local density ratios, depth spans or calibration terms cannot establish the required interpretation.
