This article describes how to create a new pipeline to receive Earth observation data at regular intervals from the EarthCache dashboard.
In this section, you will learn how to:

Selecting your first pipeline output
Satellites capture information on multiple bands at once. To save you time, EarthCache has been designed to help you easily search and find data that is most relevant to you. By selecting the bands, composites, or algorithms you are interested in, EarthCache reduces the need to sort through download unnecessary data, while also saving you processing time.
To select an output, simply head over to the Output tab of your pipeline and click on the output you wish to select.
For more info on a particular output, simple hover and select the more info button shown below:
Singular bands available
While you can access all bands through the SkyWatch EarthCache API, the SkyWatch dashboard currently do not support the ability to select individual bands other than Thermal Infrared, Near infrared, and Panchromatic. To select any other single band, you will need to select the satellite source, then select the specific band you which to search for using code.

Composite images are created by assigning one of the three fundamental colours (red, blue, green) to different bands, or by-product of. All features within a scene will have a different spectral reflectance in the various bands captured.
Different composites images formed using different spectral bands will highlight or mask features of notes within the image. To view a complete list of all available composites and their uses, please consult our Available data page.
Algorithms are formulas that are applied to the data during processing to highlight or mask features of notes within the image based on their reflectance properties. One example of algorithm is Normalized Difference Vegetation Index, or NDVI, which is a standardized way to measure healthy vegetation.
