# Environments

We recognise that remote sensing can be applied to a broad range of "environments" :

- Terrestrial: Abiotic and biotic features above the high-tide limit to its boundary layer with the atmosphere
- Marine: Abiotic and biotic features below the high-tide limit to the sea-floor
- Atmospheric: Region extending from terrestrial and marine boundary layer to the ionosphere

It is essential that you first be aware of your mapping needs , this is done by completing a table of mapping needs. This will help you select the most appropriate data and technique to use for your application.
