This is a repository of Google Earth Engine 🌎 (GEE) JavaScript code for tools for working with various hyperspectral open datasets from NASA (e.g., AVIRIS, EMIT, Hyperion, PACE OCI). One of the dependency packages included in this toolkit provides data on the hyperspectral wavelengths for NASA various spaceborne 🛰️ hyperspectral imagers, namely EO-1 Hyperion, the ISS EMIT, and PACE OCI [whose products are open data]. Another dependency provides access specifically to PACE OCI land data (since the Hyperion and EMIT data are already available via the GEE public data catalog). Aside from the dependencies, example scripts are provided to allow users to interact with the data, and the geographic and temporal scopes of those examples can be modified to meet users' needs. Please note that this repository is a successor, as well as an add-on to the PACE OCI hyperspectral toolkit available at https://github.com/BzGEO/PACE_OCI_Toolkit.
The scripts are divided into the following main functions: (i) data discovery, (ii) data visualization, (iii) spectral signature visualization, (iv) data gap filling, (v) time series analysis, and (vi) image classification.

This work builds off of the PACE OCI hyperspectral toolkit, which was soft-launched at the virtual Technical Interchange Meeting of NASA's proposed Surface Biology and Geology (SBG) mission. This work is being led by researchers from the Lab for Applied Science of the Earth System Science Center of the University of Alabama in Huntsville and has been supported by NASA Earth Action / NASA Marshall Space Flight Center. The initial work was being done in the context of an Early Adopters project for PACE. Kudos are due to Dr. Morgaine McKibben (NASA / SSAI), Skye Caplan (NASA / SSAI), and Dr. K. Fred Huemmrich (NASA / UMBC) of the collective PACE team, Dr. Africa-Flores-Anderson (NASA) of the former SBG team, and to Kelsey Herndon, Eric Anderson, Dr. Kevin Horn, Dr. Ashutosh Limaye, and Dan Irwin of NASA MSFC.
