Warning

Awesome Spectral Indices is being migrated to v1. The v1 catalogue and schema are experimental and may change while the migration is in progress. Existing APIs continue to use v0 until their individual migrations are ready.

Read v1 Explained for the current schema, implemented changes, and migration status.

Important

Call for Indices! Researchers who have published—or aim to publish—their novel spectral indices are encouraged to add them to this repository. To add an index, follow the Contribution Guidelines.

If you know a spectral index that is missing, or find an error in an existing entry, please open an issue. There is no deadline; the repository is continuously updated.

Spectral Indices

Spectral indices are widely used throughout the remote-sensing community. This repository curates classical and novel indices for different Earth-observation applications and makes their definitions available across programming languages and processing environments.

The README now follows the experimental v1 catalogue. Browse the generated CSV table, or download the raw CSV and JSON files.

Properties

Each v1 catalogue entry has a case-sensitive lookup key and the following primary properties. Nested objects contain additional generated and contributor-provided information. For the complete schema and validation rules, visit v1 Explained.

Property	Meaning
`acronym`	Required display acronym; it does not have to be unique.
`name`	Required full index name; it does not have to be unique.
`formula`	Validated v1 mathematical expression.
`classification`	Application domain, generated sensing modalities, and optional families.
`bands`	Generated spectral, thermal, and hyperspectral inputs.
`polarizations`	Generated radar-polarization inputs.
`constants`	Per-index definitions for constants used by the formula.
`external_variables`	Per-index definitions for formula inputs supplied outside spectral data.
`reductions`	Execution context for contextual reduction functions.
`source`	Source link plus generated status, metadata, and citation data.
`contributor`	Contributor GitHub profile URL or email address.
`date_of_addition`	Catalogue contribution date in YYYY-MM-DD format.

Formula expressions

V1 formulas are validated mathematical expressions. Their variables are classified into broad spectral or thermal bands, exact or selectable-range hyperspectral inputs, radar polarizations, constants, and external variables.
