Planet Overview
Leaf provides an integration with Planet, fetching PlanetScope images from a back-fill and forward-fill specified by the user.
We generate 4-5* multi spectral bands and a total of 16-17* images between RBG, NDVI, and NDRE GeoTiffs. PlanetScope provides numerus categories of products from different
satellite sensors called itemTypes and for each one, we have different assetType. For now, we only support PSOrthoTile and the assets analytic_5b, analytic_sr, and udm2
for more information on those assets check the documentation.
Also, Leaf handles all the subscription process internally in order to bring foward-filled images as area available from Planet.
The following table shows all the images with its resolutions and types: (TIFs are EPSG:4326, PNGs are EPSG:3857).

* The red edge image will be available by using the assetType: analitic_5b (red edge band) where the default value is
analitic_sr which are images with atmospheric reflectance correction.
See the Satellite API Reference for more information.
